I am in the process of converting my Uber Point Cloud based shaders into individual shaders for use with one specific effect with 3Delight.
3Delight: Atmosphere – Point Cloud Baking
3Delight: Light – Point Cloud Ambient Occlusion
3Delight: Light – Point Cloud Global Illumination
3Delight: Light – Point Cloud Glossy Reflection
