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

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)

New prototype of VRC Light Volumes real-time shadows! It uses EVSM сontact-hardening soft shadows. Performance seems good on PC, but I will do more tests. Finally something that looks better than what you can achieve in Unity by default!

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.

Here's something I promised to show you… GPU grass that is actually fast and usable! It can be dynamically scattered over any mesh in your scene, can be bent by people's avatars or props, and it even works on Quest and mobile just fine. Still WIP, but you can check this world:

Today I improved GPU Grass with a feature I call "batched instancing". It builds a grass batch at runtime and instances it. No world size increase, less GPU memory usage, runtime grass amount control, and better perf. 144 FPS with 11.2M grass triangles visible to the horizon!

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!

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.

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!

My grass system is now closer to the release! It's now possible to draw up to 3 types of grass, or even more, but randomized or sorted by size. You can draw it on top of any mesh with the brush instrument I provide, or with vertex color paint in Blender.

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.

Only two days left until 2026, and I'm releasing a new GPU Fireworks asset to celebrate the New Year! It includes timer that launches fireworks at each time zone. You can also generate any firework mesh you want! And it lights up the world with VRCLV.

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...
