LR - Grand Theft Auto V

ToM · May 14, 2019

wie installiert man denn diese Mod??

SolKutTeR · May 14, 2019

Schau Dir mal Beitrag #18 an, vielleicht hilft dieser weiter.
GTA: Vive Alpha 0.1 ist jedoch nicht mehr aktuell gewessen, die letzte Version war Alpha 1.2.
(Ob das ganze jedoch noch mit aktualisierenden ScripthookV und Spielupdates funktioniert?)

Halte uns auf dem laufenden.

ToM · May 14, 2019

Also ich habe es versucht nach dieser Anleitung hier, ich habe keine Steamversion. Ich bekomms leider nicht zum laufen

SolKutTeR · May 14, 2019

Das ist schade, die Geschichte mit der "commanline.txt" haste auch versucht?

ToM · May 14, 2019

Ja habe Text Datei mit dem "commandline.txt" inhalt:
-width 1152 -height 1280 -framelimit 0 -windowed

SolKutTeR · May 14, 2019

Hmm schade, hätte mein Flat-optimiertes GTA sonst wieder VR-Fähig gemacht.
Falls Du hartnäckig genug bist und dennoch über eine Lösung stolpern solltest, halte uns bitte auf dem laufenden.

ToM · May 19, 2019

Servus bin grad bei nem Kumpel der gta auf Steam hat. Das Spiel startet aber nur im Kinomodus. Man muss L drücken laut Anleitung aber da passiert nix. Hat jemand nen Tipp

Habe leider selber noch nicht rein gesehen, aber von dem User LukeRoss00 gibt es eine neue VR Modifikation.

R.E.A.L. mod for Grand Theft Auto V - 100% VR!

GTA V is a masterpiece. In my opinion, it builds one of the most believable, enjoyable and detailed virtual worlds ever created in videogame. So, it pained me a lot that I couldn't experience it properly in VR. There were a couple of VR mods out there, sure, but they're mostly Vive-centric, outdated and basically don't work correctly anymore, or at least I couldn't make them work well enough to get the feeling of immersion that I craved. I was looking for a mod that would allow me to play the FULL game from start to 100% completion on my Rift, and to leisurely spend my time strolling or driving through the incredible locations of Los Santos and Blaine County, with a feel that was as close as possible to that of a native VR game.

Since I couldn't find any suitable solutions, I built one myself. If you wish, you too can now enjoy the results by going to my GitHub release page and following the quick setup instructions given at the start of the README. My mod is standalone and doesn't need vorpX or anything else installed, apart from the original game of course.

This is the second entry in my R.E.A.L. VR mod series: the first one was a VR conversion for an old gem, way smaller and less known than GTA V, but much loved by us die-hard fans: No One Lives Forever 2. You can still find that mod here (sadly, due to a stupid deadlock among huge, soulless corporations that may or may not hold some of the rights to the game, NOLF2 can no longer be legally purchased, although as usual the internet will find a way).

Getting back to the wonderful GTA V, just a couple of warnings: my R.E.A.L. mod is NOT advisable for people who are new to VR and still have to develop their "VR legs", due to smooth locomotion and in general the fast pace of the game. Also, cutscenes have a close-up camera that might make a few people queasy (although they can be skipped if they're too much for you). However, if you are patient and build your VR legs gradually, I believe that being able to be transported inside the amazing world that Rockstar created is one of the most beautiful experiences that can be had in VR at the moment.

I hope that you have as much fun playing this VR conversion as I had developing and, um, "testing" it!!

P.S. This mod is obviously for offline, Story Mode only. Don't try to use it for Online: it won't work, and you'd just risk getting banned.
P.P.S. If there is enough interest (say, if the mod gets more than 10,000 downloads, or if any experienced GTA modder contacts me to expand it) I will make the complete source code available.

Quick setup

I recommend that you start from a clean installation of the game, updated to the current version (1.0.1737.6), with no other mods present. Then if you wish, after you're confident that everything works correctly in VR with the R.E.A.L. mod, you can try mixing it up with other mods that you like, although I cannot guarantee that there will be no incompatibilities (a sure source of problems for example would be trying to use additional mods that modify the camera FOV).

Before installing the mod, boot up the game normally on your monitor and make the following important adjustments to the settings; when you're done, exit the game again:

Settings> Gamepad> Targeting Mode : Free Aim
Settings> Camera> Allow Independent Camera Modes : Off
Settings> Camera> First Person Third Person Cover : On
Settings> Camera> First Person Vehicle Hood : Off

Unrar GTAV_REAL_mod_by_LukeRoss.rar into the main game folder, i.e., the one where GTA5.exe is, usually something like C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V. There should be no need to overwrite any existing files: if the extraction program asks you to do that, it is probably because you have other mods installed, which you should remove at least temporarily (see point 1).

This step is very important: if you fail to do this, chances are that the R.E.A.L. mod will not work at all. Go to your Documents\Rockstar Games\GTA V folder, and make a backup copy of the settings.xml file that contains your current graphics settings. Then, replace and overwrite your settings.xml with either of the two versions that were put inside the Grand Theft Auto V folder when you extracted the mod: select Grand Theft Auto V\Settings\Low\settings.xml if you have a low-end system, or Grand Theft Auto V\Settings\High\settings.xml if you have a high-end system. Later on, if you are so inclined, you will be able to refine the settings to your liking as explained in the Advanced tweaking section, in order to find the best possible balance between graphic quality and frame rate.

Remember to set your Windows default audio device to the Rift headset, otherwise you will have no sound in game (this step can later be automated with the Oculus Tray Tool by creating a profile for GTA V and enabling the Audio Switcher).

Put on your Rift, pick up a gamepad if you wish, launch the game and marvel at the beauty that is Los Santos in VR! Whenever you need to recenter your view or to realign the HUD in front of you, just shake your head briefly as though you were saying no (more details in the Recentering your view section below).

In-game HUD
After several experiments, I settled on a solution that I believe is the best compromise between ease of access to the various information fields available on the HUD (such as game hints, ammo, subtitles, and especially the all-important radar) and the necessity in VR to keep the HUD out of the way so that it doesn't detract from immersion in the game world.

In my implementation, the HUD is semi-transparent, suspended in space about 3 feet in front of your head, and it is:

slightly larger than your field of view in VR, so you'll have to turn your head a little in the direction of the HUD element that you want to observe; this way, your normal line of sight isn't occluded by the HUD elements;

fixed in space, instead of somehow rotating after your head with some delay or inertia, a trick used by some games that I personally find very distracting and basically impossible to get right.

A notable exception happens when you are aiming, in which case the HUD will become smaller and headlocked, so you'll always have all the information that you need visible in front of you even when you have to rotate your head quickly to follow enemies.

In the end, if you play sitting on a couch or at your desk, the HUD will always be in front of you, just at the margins of your field of view. If you play in roomscale and you need to turn around, you can reset the HUD position (bringing it again in front of you) anytime you want just by shaking a no with your head, which will recenter the headset as described in the Recentering your view section below.

Keyboard/mouse, controller, aiming
For my previous VR conversion of No One Lives Forever 2, a game that offered no native gamepad support because it was developed before gamepads became common for gaming PCs, I had to come up with custom bindings for the many controls needed. GTA V is way more advanced in that regard, and it will support basically every kind of controller that you throw at it. I have played every mission and activity from "New game" to 100% completion with all Gold medals, fully in VR, using an Xbox One gamepad. There are no special commands needed for VR, apart from the headshake gesture described below to recenter the headset view. Keyboard and mouse will perhaps feel less immersive (the controller vibration does wonders to make you feel like you're actually driving on bumpy roads), but they will also allow you to bring the game to completion.

Oculus Touch controllers, however, are NOT supported. Perhaps someone will add them in by forking the source code that I'll provide, but it's not something I'm personally interested in doing, for various reasons:

GTA V needs all the buttons you can find on a controller, while Oculus Touch sadly lacks the D-Pad;

GTA V is a long game, and since the main focus for this mod is being able to complete 100% of the game in VR and to leisurely admire the beautiful and incredibly complex world that Rockstar created, you need to be able to play seated and without holding your arms out in front of you for hours on end. Mimicking a real gun with the Touch controllers can be great fun for a short time, I know, but there is no shortage of gallery shooters to play on the Oculus store if that's your bread and butter;

perhaps most importantly, both NOLF2 and GTA V were built and designed with traditional FPS aiming in mind. I'm much more interested in preserving the original charm of the games as they were intended to be played, with beautiful animations and precise aiming, than I am in drawing a disembodied, floating gun in the air and perhaps tacking a laser pointer onto it in order to make some sort of aiming possible.

For the same reasons, I went to some effort to implement dominant-eye alignment when rendering the weapon model, so that you can properly aim down the sights as you would in real life. See Advanced tweaking later on for information on how to select your dominant eye (default is the right one).

If this is your first time trying out a mod with head-driven aiming, don't let yourself be discouraged by detractors: aiming with your gaze becomes completely intuitive in just a few minutes, it can be done equally well if you play standing in roomscale or seated, and it's way faster and more accurate than aiming with the hand controllers. Again, this is not to say that games built purposely around the Touch system are not fun; they are. However, they do become quite hard on the arms in just a few hours, and as proven by Rockstar's very own partial port of L.A. Noire, that doesn't work so well for vast open-world games.

Recentering your view in VR
GTA V has quite a few intense moments; so, especially if you move around a lot in roomscale, you may frequently find yourself needing to recenter the view, in particular to reset the HUD to be in front of your line of sight, or to realign the position tracking with the character model (see also Position tracking below).

You can use the Dash menu by pressing the Oculus button on the controller, but much more conveniently, you can just briefly shake your head from side to side as if you were saying no. This recentering gesture is always available and recognized, no matter if you're in a mission, free roaming, in the menus, loading the game, and so on. The movement will become second nature in a short while, and I find it so convenient and have become so accustomed to it that I sometimes catch myself doing it in other games and wondering why it didn't work

If you cannot seem to trigger the recentering, follow these instructions:

keep your head quite still for a second: this is needed because we don't want to have false triggers when you're jerking your head around continuously, e.g. during combat;

give a rather sharp shake to the left or the right (a single one is enough, even though the mod can also deal with repeated shakes) and immediately return your head to the initial position. By sharp I don't mean so hard as to hurt your neck or to have the headset slide around on your face: just enough to allow the mod to reliably distinguish the movement from a normal look-around motion;

the mod will wait for a fraction of a second to allow your head position to stabilize, and then it will instruct the Oculus runtime to recenter the headset. There will be no visual or acoustic feedback that the recentering has happened, but you'll always be able to tell because the HUD will snap back in front of you (and so will your vehicle if you're in one).

Cutscenes
In my previous R.E.A.L. mod for the almost forgotten gem that is NOLF2, I was able to offer a lot of options for viewing cutscenes, so they could be enjoyed by all kinds of people, from those who have built sturdy VR legs down to those who immediately get sick as soon as the camera moves.

GTA V is much more rigid in its management of the camera during cutscenes, and to the best of my knowledge it is impossible to even properly set the cutscene camera FOV from a mod (though if you're a modder and you know different, please see your section further on and get in touch with me). So, cutscenes will be very immersive, but perhaps a little too hard on some players: the camera will zoom in on characters and move around a lot, just as it does in the original 2D version. You'll be able to look everywhere in roomscale and see all kinds of hidden details, however, which I hope more than makes up for the discomfort!

If you read Advanced tweaking below, you'll find that there is one option for pitch control that you can modify, and you can also force the FOV, which gets rid of the zoom effect but introduces all kinds of artefacts as described in Car wheels in the sky. In case of panic, just remember that all cutscenes can be skipped after a second or so by pressing 'A' on the controller or the left mouse button.

My advice is, if you tend to get sick during cutscenes, just keep very still and don't try to follow or to counteract the motion of the camera with your own head. Also, don't push it: as soon as you start to feel queasy, take a break and don't try again until you feel completely OK. With these simple tricks, you'll build your VR legs in no time!

Position tracking, animations, and the player's body model
With NOLF2 I was able to implement full position tracking because the game provided a way to move the main character model accurately by an arbitrary, precise amount. GTA V does not, or if it does, I couldn't find out how. However, position tracking is extremely important for immersion: being able to look around obstacles, for example, or doing stuff like leaning forward and looking up at the moon through your windshield when you're driving around at night, makes the virtual world feel so much more real (R.E.A.L., ha-ha). It makes you feel there. So, position tracking is active by default, although it can be disabled as described in Advanced tweaking.

There's a caveat though. For the technical reasons that I just mentioned, the offset that you apply to the camera when you move your head in real life does not carry over to your character's head, or body. Actually, if you move around too much while in 1st person, you'll quickly find out that GTA V's body model for the player character does not even include a head! Your character's body ends at the neck with a beheaded stump, and that can be quite disconcerting the first few times that you see it. Be advised!

There are also a few circumstances when the game will just take control of the camera, which represents your head, and will make it do whatever it goddamn pleases without heeding your input. That happens for example when you enter a car (as you know, that animation is extra-long if you are committing grand theft auto), when you get thrown from a vehicle, when you slide down a slope, when you roll on the ground, and in other situations of the sort.

All of that can be quite jarring if you haven't yet fully developed your VR legs. Please follow the advice given in the previous Cutscenes section, and as an even stronger recommendation for in-game animations, don't try to fight the camera. Just go along for the ride, let it do what it wants to do, perhaps even close your eyes for a few moments if you feel queasy, and simply wait it out.

I see car wheels in the sky, WTF?!
In VR, one of the most important requisites for immersion and to avoid motion sickness is making sure that the FOV (field of view) of the game camera exactly matches the headset's. So, a VR mod has to somehow coax the game into always using the same FOV. The modding community has discovered a few ways to tweak the gameplay camera FOV in GTA V, which made this R.E.A.L. mod possible, but no universal solution has been found, at least that I know of.

So, even though most of the time I'm able to properly set the camera FOV in a way that allows for correct rendering of all objects, there are situations when I have to forcibly override the field of view during the rendering process itself, which leads to some pop-in at the edges of the image (the game was expecting to draw a narrower portion of the world, so it didn't load some parts of it in time), and most notably to some objects in the world being drawn at the wrong positions. This includes car wheels, suspended wires, shadows and clouds.

A situation where you'll frequently experience this problem is if you, uh, interact with a hooker in your car. In that case, just concentrate on what happens inside the car, and never mind the wheels floating around outside Another occurrence of this is during cutscenes, but only if you force the zoom override as listed further on in Advanced tweaking.

Advanced tweaking and hotkeys
In the Grand Theft Auto V\Settings folder that gets created when you extract the mod, I have provided two template versions of the settings.xml file, one of which should be copied over to your Documents\Rockstar Games\GTA V directory to provide a starting point for your own customized graphics settings.

If you want to tweak those templates to further tune the game performance to your specific system, with the goal of keeping a steady 90 fps while at the same time enjoying the fullest graphical quality, there are a few important things which you should keep in mind. First of all, the settings given in the following table must always be honored for the mod to work properly:

Settings> Graphics> Aspect Ratio : must be Auto
Settings> Graphics> MSAA : must be Off
Settings> Graphics> Shader Quality : must be either Very High or High
Settings> Graphics> In-Game Depth Of Field Effects: recommended Off
Settings> Advanced Graphics> Frame Scaling Mode : must be either 5/2 (x2.500) or 2/1 (x2.000)

The mod also assumes that you are running the game with a square resolution (which can normally be set only in windowed mode). The high-end template file uses 1080x1080, and the low-end one starts from 600x600. Note that this is not the resolution which will be sent to your headset: the mod leverages the internal workings of GTA's RAGE engine to render the in-game world at a much higher resolution, as specified by the Frame Scaling Mode value.

Running the game in a square window is very important, because due to the way the Oculus Rift manages the two eye buffers, letting the game choose a 4:3 (or even worse its preferred 16:9) aspect ratio would result in lots of wasted pixels, i.e., pixels which would be rendered by the game engine but could never be seen in the headset, causing a big performance loss. You definitely don't want to do that!

Unfortunately this also means that most of the graphics settings cannot be tuned while in game, but must be changed by hand in the Documents\Rockstar Games\GTA V\settings.xml file after quitting, because although GTA V can work with custom resolutions, it doesn't seem to remember them when it re-initializes the renderer after non-trivial graphics settings have been modified. In practice, what will happen is that GTA V will reset the resolution to 800x600 any time you make a significant change, and the mod will stop working or behave oddly. So, unless I or some other modder manage to come up with a trick to always force the game to use a custom resolution, what you should do is tweak your graphics settings directly by editing the settings.xml file after you have quit the game, instead of using the menus. Or, perhaps more easily, you can modify the settings from the game menus, which will revert the resolution to 800x600 after you apply them, and then quit the game and edit the settings.xml file to put back the desired square resolution before you launch GTA again.

The R.E.A.L. mod offers some advanced options that you can tweak in real time while playing, by using keyboard shortcuts (hotkeys). The hotkeys are disabled by default, to avoid possible problematic interactions with other mods that use the same shortcuts, and also to guard against apparent quirky behavior of the R.E.A.L. mod if the keys get hit inadvertently during gameplay. To enable the hotkeys, press F11. If you want to turn them back off after making your tweaks (the changed options will remain set until you quit the game) just press F11 again.

Here is the list, with the initial value of each option:

F11 Toggle hotkeys - off at start
T Cycle dominant eye for aiming down sights (none, left, right) - right at start
Y Toggle heading control - on at start
U Toggle pitch control - on at start
I Toggle decoupled 3rd person camera - on at start
O Toggle view fix enable - on at start
J Cycle pitch mode in cutscenes (absolute, relative, cut relative) - cut relative at start
K Toggle full camera tracking in cutscenes - on at start
' Toggle slow motion - off at start
N Toggle HUD markers and FPS - off at start
- Cycle HUD tracking mode (normal, force fixed, force headlocked, developer) - normal at start
NUMPAD / Recenter HMD - centered at start
NUMPAD - Toggle VR enable - on at start
NUMPAD . Cycle zoom override (never, only cutscenes, always except cutscenes, always) - never at start
NUMPAD 0 Toggle position tracking - on at start
NUMPAD 2 Toggle stereo rendering (alternate eyes) - on at start
NUMPAD 3 Toggle darts/tennis FOV override - on at start

Fixes included in the R.E.A.L. mod
Here's a (probably incomplete) list of all the stuff that I needed to fix in order to achieve a fully immersive VR environment for GTA V, and to allow playing the game to 100% completion without ever needing to remove the headset:

1st person camera while on foot:

patched the walking FOV to match the headset's (with updated signatures for game version 1737.6)

patched the crouching FOV to match the headset's (again, with updated signatures for game version 1737.6)

moved the player character's phone away and to the left, as otherwise it would be way too close to the eye camera and tucked into a corner to be legible

tied the character's heading to the direction the player is looking at, so "forward" on the keyboard/controller stick will always correspond to "forward" in the visible game world (selectable)

pushed away the weapon models that would otherwise be uncomfortably close to the eye camera (variable offsets depending on the aiming conditions)

1st person camera while in vehicles:

patched the FOV to match the headset's

we can finally look wherever we want when driving, yay!

3rd person camera while on foot:

patched the FOV to match the headset's

decoupled the camera angles from the position, so that the player can look around with the headset and separately orbit the camera around the in-game character using the mouse/controller

3rd person camera while in vehicles:

patched the FOV to match the headset's

aiming camera:

dynamically changed the crosshair depth (distance from the eye) to always match the depth of the object that the player is aiming at

recognized when the player is aiming down the sights and moved the weapon so that it aligns with the dominant eye (selectable)

applied a special-case treatment when the player is aiming from a vehicle in 1st person

applied a special-case fix to the crosshair for armed vehicles (e.g., the P-996 LAZER)

all cameras:

stereoized the world rendering by shifting the in-game camera into the eye positions on alternate frames (see the first question in the FAQ)

tied the yaw (left/right angle, also called heading) of the in-game camera to the headset's relative yaw

tied the pitch (up/down angle) of the in-game camera to the headset's absolute pitch

overrode the game's stringent limits on camera pitch, especially in vehicles

applied a supplementary view fix during rendering to perfectly correct the camera angles and position even when the in-game camera resists being changed

tied the roll (lateral tilt) of the rendering camera to the headset's roll, relative to the vehicle roll when the player is in a vehicle

fixed the really close camera coordinates (used e.g. for the player's character body model)

fixed the helmet and masks (a special effect applied in 1st person, e.g. when your character is wearing a helmet while riding a bike)

provided a way to forcibly override the camera zoom if desired

added position tracking so you can look around objects and freely adjust your driving position in vehicles

fixed the problematic "look behind" control

fixed the yaw control for several corner cases where the game wrestles you for ownership of the camera (sitting on the couch watching TV, climbing ladders, drinking at the strip club, interacting with Chop, swimming, ...)

cutscenes:

adjusted the camera so you can look around freely while a cutscene is playing

added position tracking so you can peek around objects

recognized scene cuts so the view direction can be reset (adjustable)

suppressed the black bars

HUD:

fixed a game issue where if the aspect ratio is not 16:9, the left and right sides of several menu pages would get cut off the screen

forced the game to use the video card to which the Oculus headset is attached

limited the D3D11 maximum frame latency to 1

fixed heading control while swimming

fixed the special case for heading control when the player is entering a vehicle

fixed a number of post-processing effects that would incorrectly be applied to the HUD instead of the eye buffers, like for instance fade-ins and fade-outs, underwater distortion/blurring, ...

fixed the vignetting effect (used e.g. with rifle scopes)

fixed the scope border (used e.g. for pier telescopes)

fixed the yellow and blue markers (used e.g. for race checkpoints and mission locations)

fixed the golf trails (used to show the ball's predicted trajectory)

fixed the FOV during darts and tennis games

fixed the FOV for the fairground rides and the cable car, just check them out!

fixed the FOV for the cinemas and the strip club

forced the FOV when you are being entertained by a hooker in your car (some artefacts visible outside the car)

fixed the darts reticule (the twitching cursor used to aim when playing darts)

fixed the body bag zipper in Dead Man Walking

fixed the binoculars effect used in some cutscenes

fixed some missions that use peculiar ways of controlling aiming (shooting from dinghy, defending Cargobob, ...)

fixed the erratic camera control when shooting from a heli as a passenger

fixed the special HUDs and target markers used in some missions (like Eye in the Sky, Caida Libre, ...)

fixed the Snapmatic camera shutter effect

fixed the stunt jumps slow-mo camera

fixed the 3rd person special camera when mopping the floor in The Bureau Raid

added an in-HUD fps counter to monitor performance while playing in VR

detected many special game states (e.g., booting, loading a mission, paused, browsing the in-game internet, using an ATM, closing popups at Life Invader, ...) to bring the HUD in the foreground and adjust the aspect ratio

added a slow motion control that can be used to make magic moments in VR last (almost) forever

Please note that except for the troubles with the 1:1 aspect ratio and the menus being cut off to the sides, all the above problems are not bugs with the game per se, but only issues that stemmed from the VR conversion (similarly to what happens when a game meant for a 2D monitor is coaxed, with the help of 3D Vision, into performing stereoscopic rendering). In truth, I've found GTA V to be unbelievably stable and bug-free, especially when you consider the huge complexity of its open world.

Also note that when the game is being forced to do something that Rockstar's original implementation would forbid (like looking all the way down toward your feet, especially while in a car) there might be some artefacts and/or camera twitches. The same can happen in cutscenes, particularly if you're looking in a different direction than the game expects.

FAQ
Q. Mmmhhh... When I drive at speed and look sideways, or if I turn around quickly using the mouse/controller stick, everything looks sort of double... Did I smoke too much weed?
A. Perhaps, I wouldn't know! But seriously, that is an artefact of the alternate-eye rendering used by this R.E.A.L. mod. Stereoscopic rendering, which is essential in VR, would require the scene to be drawn twice as seen from the two eye cameras, and at the exactly same moment. GTA V, however, doesn't allow you to render the world twice without some time passing between frames (and without every moving object/NPC in the world animating), and besides, no PC configuration that I know of would be able to play GTA V at a stable 2x90 = 180 fps with the high FOV, quality and resolution necessary for VR. So, my solution is to render just one eye per frame, and display the previous frame for the other eye; such a trick is sometimes called alternate-eye rendering. Perhaps an example can make this clearer: let's say that at frame 99 the right eye was drawn, and let's call this frame 99R. At frame 100, the left eye will be drawn, and displayed together with the previous rendering of the right eye: 100L - 99R. Then at the next frame time we'll have 100L - 101R, then 102L - 101R, and so on. This means that full frame rate can be achieved in VR with the game engine "only" needing to pump out 90 fps, but it also means that one of the two eyes will always have 11 ms of additional latency, which leads to some doubling of objects that are moving quickly relative to the camera. No doubling will be seen when you rotate your head, however, even if you do it very fast, because I took provisions to have the Oculus runtime compensate with Asynchronous Time-Warp.

Q. Okay, that was all very nice and technical, but alternate-eye rendering makes me queasy. Can I disable it?
A. You can disable it, but you will lose the 3D effect (as I said, there is currently no way of achieving 90 fps in stereo with GTA V without alternate-eye rendering). See the Advanced tweaking section for instructions.

Q. I can't control/rotate the camera while doing XXX, and also during mission YYY.
A. The game allows you to perform MANY different actions (walking, running, driving, flying, swimming, shooting, shooting while driving, shooting while being driven around by NPCs, playing sports, etc.), and not all of those situations are consistent about the various ways employed to control where you're looking, where you're firing and where you're going. To complicate matters, mission or activity scripts often use their own, peculiar control schemes. I fixed as many corner cases as I could find while going through every mission/variation and activity, so that with the current version of the mod and the game, you should always be able to control the camera in VR, usually just by looking around with your head and/or using the mouse or right stick on the controller; sometimes, the left stick might be needed; in rare occasions, one of those controls might be disabled (a notable example is when you are shooting from a helicopter as a passenger: I had to disable headlook because it was too erratic due to the specific behavior of the mission script). So, try looking around with your head, using the right stick/mouse, and/or the left stick; if nothing works, please open an issue on GitHub and remember to be very specific about the situation where it happens and any additional mods that you might be using.

Q. I hate shitty mods where you have to aim with your head, I'll just wait for a proper one that uses motion controllers.
A. Okay.

Q. Smooth turning makes me sick, please add snap turning.
A. At the moment I have no plans to do that, because turning with the mouse or the right stick on the controller is not managed by the mod but by the game itself. Also, I personally find snap turning horrible and immersion-breaking. However, since I'm going to publish the full source code for the mod sooner or later, perhaps some other developer will jump in to make a snap turning patch. In the meantime, if you are bothered by smooth turning, you can just play in roomscale and always use your head to look around just like you would in real life; as I mentioned above, through all of the game missions and activities there are only a couple of brief scenes where headlook had to be disabled.

Q. Please make a VR mod for game SuchAndSuch 6, I've never programmed in my life but I know it can't be too hard, I believe it shouldn't take more than a couple of hours. I can spare a few bucks if you give me your PayPal.
A. This R.E.A.L. mod, as the one I made for No One Lives Forever 2, was a labor of love. Modding GTA V was actually even harder than NOLF2 (to the point of becoming soul-crushing at times), because it took a lot more reverse engineering and trial-and-error, and because the game is so much vaster. I poured all of my free time for almost three months into this project. So no, sorry, I won't mod your game, although I can do consultancy work if you are a serious developer/studio who wants to port an old or new game to VR, and you have a reasonable budget to allocate to the job.

Q. I am John Bigcheese with Rockstar Games; I just spoke with Eddie Megaboss at Take-Two Interactive and we decided to send a golden plate to your home address for making one of our flagship games so much more beautiful and for all the additional sales that your mod generated... where do you live?
A. Just PM me! But seriously, I made this mod out of passionate love for the game and the magical world it creates. If it pleases you, that makes me happy; if it interferes with your present or future plans for the game, just ask nicely (no need for any C&D, Rottweiler-lawyer stuff) and I will take it down right away.

Q. I'm reckless and I want to feel (well, imagine, perhaps with some help from my USB fan) the wind in my face while I'm driving by setting the camera to "First Person Vehicle Hood", why did you write that I can't?
A. Actually you can, and it is kind of exhilarating if you have the stomach for it. The only reason why I'm suggesting to leave that setting Off is that you won't be able to aim by rotating your head while driving and you'll have to use the mouse or right controller stick instead, which makes several missions much harder.

I am an experienced GTA modder and I wish to contribute, where do I begin?
There are several areas of improvement where the R.E.A.L. mod could really benefit from your input, especially if you know or can find out the answers to these problems:

Is there a way to reliably set the FOV for the cutscene camera (either with natives or more realistically by patching the game code)?

Is there a way to control the FOV of the main gameplay camera during transitions? The most frequent and annoying transition being the animation where the player character enters a vehicle.

It would be helpful if there was any kind of trick to force the game to always use some specific, non-standard, windowed resolution, to work around the issue where if you change any of the Graphics settings that require the renderer to re-initialize, the game will immediately reset the resolution to 800x600 making the mod unusable.

This is probably impossible without source access to the game engine, but worth asking anyhow because it's so important: has anybody found a way to render the same frame twice, without any change to the world (no time passing between the frames, no advance in animations, etc.) except for the gameplay camera being moved to a different position? This could enable ultra-high-end systems to render both eyes at exactly the same game time, getting rid of the doubling associated with the alternate-eye rendering technique.

This one is a lot of complex work for relatively little benefit, so only consider it if you love hard challenges and have plenty of spare time on your hands: it would be nice to split rendering of a. the really-close objects attached to the camera (hands, weapons), b. the player's body and vehicle, and c. the rest of the world, into three separate Oculus SDK layers, so that correct ASW/ATW could be applied to each of them, which is especially important for the "stale" eye, i.e., the one that is not being rendered for the current frame. The result could approach the visual quality and stability of simultaneous eye rendering, but again, it's quite a big effort and there are no guarantees. If you want to tackle this problem, and you are knowledgeable about all of the areas involved (GTA modding, 3Dmigoto, and native rendering with the Oculus SDK), please contact me.

I've tried several times to fix aiming while the player's in 1st person cover, but new issues keep cropping up, so in the end I gave up and resorted to the "First Person Third Person Cover" workaround. I have a nagging suspicion that the developers put this option in the menu because they too weren't completely satisfied with the implementation If, after looking at the code, you have fresh ideas to make it work reliably (in particular when the player is aiming towards and across the cover, instead of away from it) please let me know.

If you are a VR C++ developer with a non-Oculus headset and you want to undertake the semi-arduous work of making a native SteamVR/OpenVR/OpenXR version of the mod, do get in touch and I can give you pointers to get started. It would help a lot if you also have experience with the Oculus SDK.

Does anybody know of a technique (e.g., a native call) to reliably find out when a 1st person animation is being played? For instance, it would be nice to have the option to disable user control of the camera when the character is rolling on the ground during combat. Note that this is different from ragdolling, which I already know how to detect.

Can the non-graphics menu settings (e.g., "Allow Independent Camera Modes") somehow be controlled programmatically or through an .ini file, so that the mod could make the few tweaks it needs at the beginning without user intervention?

Hier ein kleines Testvideo von Tomasz Brodecki.
(Das Zittern kommt von der Überschneidung der Bildinformationen des linken und rechten Auges.)

The "shaking" effect is a result of storing left-eye and right-eye frames in a single video file.

Ja, das werde ich heute Abend gleich mal testen. Das Video macht natürlich keinen guten Eindruck, aber das Zittern ist eben nur im Video und nicht in VR zu sehen. NOLF2 Mod lief ja ganz gut, dann bin ich mal gespannt auf die GTA5 Mod!
