I'm working on a new major VRC Light Volumes update! - Baked realtime shadows (very performant) - Animated cookies and cubemaps - Optimized area lights - No more legacy code - Almost full back compatibility with older light volumes shaders (excluding new shadows)

Point Light Volumes prototype! They can be both Point and Spot Lights, can be calculated mathematically or use a special LUT texture that controls the cone falloff and attenuation! Up to 128 lights per scene. Works up to 3- 4 times faster than regular Light Volumes. Can also be controlled with AudioLink individually!

Something-something Point Light Volumes? Not sure if I will integrate it, but I just don't like people using baked volumes as fake point lights and spot lights. Integration for shader makers would just require to update my .cginc file I provide. For people - to update the shader and reupload their avatars again. Not sure if it's worth it, but we'll see...

Light Volumes 2.0 will support baked 3D shadows for point and spot lights, and that's how it can be used! Thanks to Pema99 for implementing this feature!

Spot Light Volumes! Everything is parametric here and not baked into a 3D texture, as regular light volumes, which makes it even more optimized. Will work on it a little bit more and see if it's worth to add it to the main project branch.

I have been working on a side project that adds moving and interactable Grass. This shader supports Light Volumes made by RED_SIM! No baked Lightmaps (in grass) or Real-time lights! #VRChat #VRC

This week I've been working on the VRChat Light Volumes scripts to bring you an easy and comfortable editor workflow. I also implemented the Volumes rotation feature and optimized the shader a lot to make it work even more solid on potatoe-PCs. Here's a small video of how it currently works.

Today I release new GPU Particle Volumes system and the GPU Snow Particle shaders for it! This snow shader can render hundreds of thousands of particles at the same time even on a weak GPU. It also supports VRC Light Volumes. Get it on my Booth or Patreon!

Another thing that is going to be released with next version of VRC Light Volumes, is an in-game debugger tool! You'll be able to preview every volume, voxel, and point light. Works in any world that supports VRC Light Volumes.

Doing a little experiment with splitting light channels to "paint" light and shadow directly onto a model in a way that still respects area lights.

Noticed this Cyclist did not have reflective lights and flash light also no street lights on our road. Decided to shield and light for him. Also magadi road can be dangerous at night as it has alot of alcohol joints, hence alot of accidents weekly due to drunk drivers.

Got the lights swapped over onto the new drill and even put extra on the tank to light it up more for the night shift. #AgTwitter

Well that’s one way to power up the lights at Sydney Showground Sydney Olympic Park ! Lightning struck a light tower and the lights came on! #SydneyStorm #Sydney #Storm

Now Point Light Volumes supports Cubemap projections! Volumetric fog makes it look just stunning! But here's some bad news... If I release it, all world creators will need to update their worlds to the new Light Volumes version. Otherwise it will break the back compatibility. Updating avatars will be really suggested too, to support the point light volumes, but worlds are something that is more important! But it will be just as easy as to reupload the world.

A very rough proof of concept of Baked Directional AO for VRC Light Volumes. I'm not sure if I want to integrate it into light volumes for real, but it could be a VERY performant solution to make super cheap realtime contact shadows.

🔥 First look at the new “Light Sync” feature introduced in the 2025.26 software update [New 3 & Y, 2026 S/X, CT] “Accent lights now respond to music, and you can also choose to match the lights to the album’s color for a more immersive experience.”

5001 lights in WebGPU (Shade). 1 directional shadowed light with CSM + 5000 sphere lights. Using clustered lighting, similar to Unreal, the screen is split into tiles of 32x32 pixels and then further split along the Z axis. Lights are culled and binned. Most of the time engines implement clustered lighting with a fixed number of partitions in XY, something like 40x20, let's say, this is generally fine, but it doesn't adapt to different aspect ratios and tends not to scale as well into higher screen resolutions. Finally, by splitting the XY in 32 pixel increments (or anything that's 2^N really) - you get better wave coherence, that is - pixel shader runs more efficiently. The engine supports up to 10,000 so-called "local lights" in the frame, which can be either be sphere lights (point lights with volume) or spot lights. When I say "in the frame" - I mean on-screen at the same time. There can be a million lights in the scene for example, but only 10,000 can be visible at a time. Can increase the limit, but I reckon 10,000 is already a pretty (un)reasonable limit.
