VRC Light Volumes
Light Volumes are a baked lighting solution for VRChat worlds.
The voxel shader supports these light volumes. It will improve the ambient lighting that the material receives in supported worlds.
You do not need to have the light volumes package installed. The voxel shader comes with light volumes 2.0 included. If you wish to update the light volumes version to a new version, you can change the LightVolumes.cginc in Packages/gay.shader.voxel_1/Shaders to the newest version.

Beware that enabling this feature has been known to cause stutters upon loading and to increase compile/upload times for avatars.
