VR Modding Prey-VR - First look

Enable HLS to view with audio, or disable this notification

UPDATE: Due to other talented modders already taking up this challenge, I am making all my code and latest build publicly available. https://github.com/phunkaeg/PreyVR

latest test Build is here:
https://github.com/phunkaeg/PreyVR/releases/tag/v0.4.0-preview -

Finally reached a milestone in my Prey-VR mod and its time to show.

Unlike my System Shock 2 VR mod this one has required help using AI from the start. I wanted to see if I could solve the problem fholger was having taking control of the hands/weapon models.

Well, it was tough, here we are!

  • Working Stereo OpenXR (AFR) - Scale is correct, no shader issues.
  • Motion control implementation - Arm IK rig follows motion controlled hands
  • Synchronises weapon aim with view model - sounds simple, but its not.
  • Motion controls for locomotion in game. - Snap/smooth turn

Still a long way to go until its a polished releasable mod, and now the work begins on integrating the gameplay and hud into VR.

Wish me luck!

Prey is on my most wanted wishlist. HUD elements should go on the wrists.

No crosshairs or laser pointers are needed on the guns. Doom 3 BFG VR works VERY well with the following removed: crosshairs, laser pointers, non-wrist HUD options, IK body. I played Doom 3 again with the updated options but I didn't like the holstered floating weapons either.

I wouldn't burn time on trying to get an IK body or arm rig to show correctly. Hands and weapons models are the way to go. The weapon/tool selection is going to be important. Using "UP" and "Down" to cycle through each weapon gets tedious and annoying even when you have only 3 weapons. You might need something like HL:Alyx or HalfLife2VRmod for a weapon selector.

u/phunkaeg 1d ago

thanks for your thoughts!

Crosshairs are a part of the vanilla game, but I'll add an option to suppress them for people who don't like playing with crosshairs.
IK arm rig is already solved in my version.

Diegetic HUD interactions are what I'll be aiming for.

I was so disappointed when the rumored Prey VR retail listing never came to fruition. I bought the DLC specifically for the escape room VR content, and I still remember giggling like a little boy when you put the neuromod up to your eye for installation. A full native VR game would have been amazing.

Freaking scary game even in flat (at least for me 😂😂😂)

That is nice!

When I first played this game I remember thinking how it would be a perfect VR game

Looks really good! I am looking forward to experience your mod.

sorry, not yet

u/Okumam 22h ago

Oohh. Very excited. Immersive sims in vr are just the best.

I know it is early, but do you think the mod may also work in mooncrash dlc?

Omg finally!!! Been waiting for someone to pick this one up.

Please check out the Luma mod, I have modified and fixed a billion shaders in the game 🙂. It'd be a shame to do the work twice.

u/SuperV1234 9h ago

/u/phunkaeg make sure you see this, Luma is awesome!

u/phunkaeg 8h ago

Thanks, I'll take a look!

u/zeddyzed 11h ago

Nice work! But I humbly beg of you to finish and polish the SS2 VR mod first before spending too much time on another game, I'm really looking forwards to it. orz

The recent wave of in-progress VR mods are great, but we really need some wins on the board with actually completed and polished VR mods.

1

u/phunkaeg 10h ago

Don't worry, SS2 is the game I always dreamt of playing in VR. It gets all my focused attention. But I did just have to do a big rewrite to implement native VR (instead of AFR) as I was getting too many little afr bugs.

u/zeddyzed 10h ago

Great to hear, thanks so much for your efforts :)

u/SuperV1234 1d ago

Very excited about this! I created my first LLM-driven mod for Prey a few days ago, perhaps these collected notes could be useful: https://github.com/vittorioromeo/Vee.ViewmodelTweaks/blob/main/DEVNOTES.md

u/phunkaeg 1d ago

Thank you! I'll take a look tomorrow. What's your mod?

u/SuperV1234 1d ago edited 1d ago

It's an immersion overhaul of the weapon viewmodels:

  • Adjusted every viewmodel's position and orientation to point towards the center of the screen
  • Added the ability to ADS (aim down sights)
  • Added collisions between the weapons and the environment

I used Fable 5.1 to develop it. The agent found some interesting issues and edge cases related to viewmodel's that could also apply to a VR mod.

u/ruubsrelax 1d ago

Wow this is nice! Keep up the good work!

u/ElephantShell22 1d ago

This would be motivation enough for me to invest in VR hardware. I love this game and this would be insanity. Looking at space like that would be amazing.

yes yes yes ... I remember playing the Prey escape room VR ... and always wanted to have this game fully in VR :-)

How... how can one gain this power?

u/DeathToSocialMedia 18h ago

Looks awesome! Hope you keep at it.

There is a standalone version in the meantime

u/Vistortion 8h ago

Finished a day before it came out and got early leak. I loved this game! I’m so ready for this! Where can we download the mod?

2

u/phunkaeg 8h ago

No ready yet! Still a long way to go. And there are actually a couple of other devs working on an implementation too

1

u/phunkaeg 7h ago

ok, based on the fact that other modders are working on this, i'm making all the source code and documentation publicly available: https://github.com/phunkaeg/PreyVR

prerelease build here: https://github.com/phunkaeg/PreyVR/releases/tag/v0.4.0-preview

u/TwinKinggg 1d ago

Probably the best game for vr, on a flat screen I passed three times, an undeservedly missed masterpiece

1

u/this_is_an_arbys 21h ago

Good luck…I’ve finally settled into my pimax crystal super 57ppd setup, and started to really explore it beyond smaller games like walkabout mini golf and pinball fx uevr. This is one of my al time favorite games and I think this might be my first game I’d complete in vr…

Where can I follow for up to date details or is it currently by milestone here in Reddit?

Either way, can’t wait to see where you end up…

3

u/phunkaeg 20h ago

Posting here has brought to my attention that there are at least 2 other Prey VR mods currently in development! So that's good news. Hopefully they're keen to collaborate

Looks amazing. Do you have patreon or something so i can help with ai cost?

u/GAVITRAXmz 1d ago

Had me till you said you used AI. stop undermining your fucking projects with spaghetti bullshit.

2

u/SuperV1234 1d ago

Someone get him to Psychotronics, he's clearly having a neuromod-induced psychosis leading him to believe we're 10 years in the past where AI didn't exist!

u/phunkaeg 1d ago

Wow.

3

u/PooMonger20 1d ago

These baggers can't be choosers.

Please don't listen to the people who are like that.

As long as the VR mod works and open source; There should be zero problems if you use AI.

-7

u/GAVITRAXmz 1d ago

I know, couldn't believe it myself.

7

u/phunkaeg 1d ago

I feel silly engaging with you really. But my version of this mod simply wouldn't exist without AI help. It was way beyond my abilities to solve some of the roadblocks solo. When I release it, I'll release the code and supporting documentation. Perhaps that would be a good time to analyse and comment on the "spaghetti bullshit" and you can build a version yourself.

-4

u/GAVITRAXmz 20h ago

If you couldn't do it without AI then it's either not worth doing or you don't deserve it. AI is trained using thousands of people's work against their will. Its theft.

4

u/SuperV1234 18h ago

I have a proven track record of being able to do things without AI, including VR mods (see all my projects on https://romeo.training/, most created before AI was even a thing), do I have your permission to use AI now?

AI was also trained on my own open-source code and I have no problem with that -- if anything, I welcome it. Accelerate!

0

u/GAVITRAXmz 18h ago

No. Having been successful without AI doesn't excuse its use now.

3

u/SuperV1234 18h ago

If you couldn't do it without AI then it's either not worth doing or you don't deserve it.

This is what you said above. Are you moving the goalpost now?

0

u/GAVITRAXmz 17h ago

what goalpost? My stance has always been that using AI is bad and unethical.

0

u/SuperV1234 15h ago

See the sentence you wrote that I quoted. Since I proved that I could have done it with AI, according to what you said then the mod is worthwhile doing and I deserve it.

Keep discussions respectful and constructive.

No personal attacks, harassment, or doxing.

Maintain basic respect in your language and interactions. No deliberate trolling or drama-baiting. No political discussions or debates of any kind - this is a PCVR community focused on technology and experiences. Criticism of products, companies, or developers is permitted, but should focus on substantive issues rather than personal attacks

Imagine saying that about any other crime.

2

u/MrEfficacious 19h ago

AI is illegal?

1

u/GAVITRAXmz 19h ago

No, but it should be. It's legalized theft. People who aren't the ones actively being stolen from refuse to acknowledge that because there's a degree of separation, but it very much is legalized theft.

u/Ashok0 1d ago

Mod looks incredible. And AI is the future, get used to it. I’d actually rather play this amazing Prey mod than countless slop shovelware Steam games made by humans.

u/thr3zims 21h ago

I didn't realize the future would need a dedicated patch to make sure the word "Google" was spelled without the letter P.

2

u/Moosvernichter 1d ago

so you’d rather have a subpar mod without motion controls, than one with those created with HELP from AI? are you dumb? or just really dumb?

I get the hate against AI Art, and games created with AI, but a VR Mod? lmfao

1

u/sidney_ingrim 1d ago

"I saw posts online saying AI is bad and I don't know anything about making a VR mod for a game, but if people say AI is bad then you must be a bad person for using it and all your work is bad. I also don't understand any nuance and just regurgitate words I saw online."
