I was inspired by Brice Vandermoortele’s Normal Map Reprojection Shader and wanted to extend the idea to new uses. This is a novel way of texturing using lit sphere images and cubemaps. You can reproject color and normal textures to a new UV Set.
As a CGFX shader, only Nvidia cards will load this reliably, but I’ve added a arbfp1 technique that might work on AMD and older cards. Cubemaps are lower quality and don’t have any blurring using this mode.
