I made VRC Light Volumes, I guess? https://nitter.cf/t.co/fNX0P8aFPA https://nitter.cf/t.co/SDkyXpo7uE

New VRCLV Volumetric Fog I'm working on. It's a hybrid solution, semi-froxel, semi-analytical. Can be roughly 2-3 times more performant than currently available VRChat fog solutions. No visible noise at all. Very sharp point light volumetrics.

The scene here has tons of expensive VRCLV area lights, which is an absolute overkill and was made for benchmarking. Still a very good FPS. Can be optimized even more though!

i was playing around with arctic setting a bit to rest from other stuff and tried to torture test the @RED_SIM's light volumes, 26 realtime lights with tons of overlap, 250k of snow particles and... 800fps??? and i thought it was a lot to ask :>

A great asset and a must-visit world! There wasn't anything like that in VRC before.

I finally released VRCFluid: my boundless, high-quality SPH fluid simulation for VRChat worlds! 🌊 Up to 1M particles, simulated on the GPU which works without compute shaders! My demo world: vrchat.com/home/world/wrld_a… Booth page: misham.booth.pm/items/904786…

Replying to @VRChat
@VRChat @dtupper can we get feedback.vrchat.com/udon/p/e… pretty please?🥹 This would make everything I do so much more performant (fluids, shader virtual machine, complex effects...)

One interesting thing about Light Volumes is that they can be updated at runtime, allowing for baked lighting toggles! Here, I have two switches controlling two Light Volumes, plus an additional one for the light shining through the window. Everything is baked. #VRChat

By the way, you can use almost any Materials for VRCLV cookie projection, not only render textures! I just wonder what else people gonna do with it... And it works with shadow maps too

Its insane what AI can do nowadays, I've let Opus 5.5 in a loop for 2 days optimize a RISC-V emulator written in a fragment shader running in VRChat and it got to a working window manager, Doom running at playable speeds, and a an emulated GPU with OpenGL 1.x

I want to talk about a big Steam Frame problem no one seems to mention: image quality. SteamVR's streaming pipeline has a serious bug that blurs high-contrast edges. I managed to partially fix it. These are real screenshots from the headset after decoding and lens correction.

As you can see, the fix doesn't remove all the blur. That's why we need 4:4:4 color sampling. In this comparison you can see that Pyrowave looks much cleaner in my vibe-coded prototype on Frame. However, it doesn't work in runtime yet. So, Valve, please... you know what to do!

Here's the bug: SteamVR's PC VRLink shader genforencode_ps_chroma_full_stack.fxo doubles chroma derivatives that already account for 4:2:0, blurring color before HEVC. My patch averages matching 2x2 RGB pixels after sRGB conversion, then computes Cb/Cr.
