Inspired by Brice Vandermoortele’s Normal Map Reprojection Shader, Leonardo Covarrubias Looks at a novel way of creating textures using a CGFX shader to create effects like metal textures pretty easily using using lit sphere images and cubemaps where you are able to 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.”
