So, I'm curious about something. I've been poking through the art files for the different demos made with T3D, and I'm noticing something with the normal maps, particularly those used for Deathball Desert. I'm noticing that, when I look at them in WTV, the normal maps are all shades of purple, none of the green or blue that usually shows up in a normal map.
Does anyone know what software was used to generate those? And also, how are they working as normal maps with only the purple? I always thought the different colors in a normal map represented the angle of a pixel at a given point.
