VRC Light Volumes v.3.0.0 will support Area Light realtime texture emission, almost like LTCGI. Less physically accurate, but very performant!

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)

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.

Still working on VRC Light Volumes v.3.0 Here are some realtime shadows with volumetric fog... (Extremely expensive but cool)

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.

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 new clustered froxel-based lighting prototype for Light Volumes 3.0.0! It uses froxels to precompute visible light IDs, so shader don't have to iterate through every light. This scene has 128 active lights and performs around 60 FPS on Android. ~13 FPS with no clustering.

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!

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!

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.

Quantum field theory predicts that light can scatter off light, an effect beyond classical electrodynamics. Maxwells equations are linear such that two photons never interact with each other However, in reality, if you cross two light beams photons will scatter if they're energetic enough. Even in vacuum, the photons interact with the ever-present quantum fields of charged particles, like electrons, even when no actual charged particles are present But you need very high energies to see this. Thankfully we built a machine specifically to probe nature at very high energies. At the LHC, this rare process of light-by-light scattering has been observed Hidden among millions of photons lighting up the detector, physicists were able to identify 26 distinct light-by-light scattering events This CMS graphic shows how they found them:
