This asset is a modification of the PBR VEX Pathtracer shader to have PBR behave like Mental Ray's Final Gather. The goal is to decouple indirect and direct lighting and render the indirect light at a much lower quality and resolution. The result is less accurate but softer and faster rendering with PBR.
Indirect lookup takes time into consideration for correct motion blur behavior.
Filtering options for point cloud lookups.
Use this in a project for real to see if it works.
Uhh, some other stuff.
