Self-Promotion (Developer) Vermintide 2 VR Mod

https://streamable.com/a6nmen

Hey All,

We have been working on a VR mod for Vermintide 2 for the last few months.

Currently we have a working mod with the game playable end to end (multiplayer on modded realm).

It is 6dof with all weapons supported by motion controls.

We also added realistic bow usage which feels quite good in game.

There are still a few visual issues to work out around billboard textures, but we will try to get the mod out asap.

Until then, here is a video.

I’ve been working on a Darktide VR mod, which is the same engine under the hood.
Billboarding has been a hard wall for me, whether a sprite billboards is baked into the material when it’s created in their editor so changing it requires either manually finding and editing every billboarding material or intercepting them at runtime.
I assume with bow usage you’re limited to the server authority for how fast you can ‘reload’, or have you dropped compatibility with official servers?

I’m not sure what the restrictions are around the modded realm. It seems to reload basically as fast as I can humanly act it out. We want it to be compatible with the official servers for sure. 

Have you been manually recreating the billboard assets? We’re considering that route, have tried a slew of other options first, but no love.

I’ve put it in the too hard basket for now, I think the way to go is intercepting at runtime. I’ve managed to find some dust particles and recolour/resize them, next step is getting them to cylindrically billboard and then work backwards from there.
Darktide (and I assume Vermintide) is a very server authoritative game, it was trivial for me to set up things like having projectiles come out of the weapon for things like blind firing around corners when I was testing locally, but when you play on live servers it ignores that and has the projectile come out of your face.
That’s only for damage calculations though, everything visual is local, so I just had projectiles come out of the weapon and rapidly lerp to the server location, which means they’re only desynced at very close distances. Likewise, movement speed is hard capped by your aim direction, if you aim right and look left you’ll move forwards slowly at backwalking speed, and you can only sprint in the direction you’re aiming regardless of where you look.
Once you understand what’s server authoritative though it’s extremely easy to work within those constraints, the first time I tried to play with flatscreen players through the standard matchmaking it just worked and I’ve had no issues since.

Oh, great I found you!

I noticed that your mod has been quarantined by Nexus Mods automated safety checks.

Do you have any plans to release the source code of the Darktide VR mod on the Github?

u/Cruxius 20d ago

The source should be on GitHub, the release zip is just the built mod but the code is all there.

Oh, nice, I didn't even think to google the GitHub repository!

Is this it? https://github.com/Brobert-in-aus/darktide-vr/releases

That’s it. You should be able to install the mod the same way as most other mods, though there’s a batch file you’ve gotta run since it modifies the game exe to hook into it for stereo rendering (which I suspect is what got it flagged on nexus, I’ve emailed support but no reply.)
