Parallax Corrected Cubemaps in the Source Engine

Video of an early implementation. (Note: only the floor is running corrected cubemaps in this video) It’s not integrated into LightmappedGeneric or anything yet, just a custom (unlit) shader that does a basetexture read and corrected envmapping, so that’s why there’s no effect from the normal map on the corrected part of the video. Other details: Cubemaps are set to 64x64, twice the default resolution Correction bounding shapes are Oriented Bounding Boxes NEW 3 YEARS LATER 2 YEAR LATE UPDATE: http://13t
