LTCGI
LTCGI is an optimized plug-and-play realtime area lighting solution using the linearly transformed cosine algorithm for standalone Unity and VRChat. When enabled in Poiyomi Shaders, it can dynamically illuminate your mesh and sample realtime reflections from a World that is actively producing LTCGI.
For more detailed information on this system, visit the LTCGI Documentation .
In this demonstration, the video player is reflecting off of the avatar's eye, and the light is dynamically illuminating the face and the environment from LTCGI.Anim Toggle
