Tropical Freeze Textures: the TXTR format. RTB and Parax pretty much figured it out.

Time for more findings. Double post.

I looked inside a ARC file in the TF WUD called "MaterialArchive". It seems to contain method names for dealing with textures and materials. I don't know if this file actually would help decoding the TXTR files, but it may, I'm just not certain. The file is ~24MB large and references a lot of stuff like normal maps, texture coordinates and something called "UC" at the beginning of each name.

I've uploaded MaterialArchive.arc so people can poke inside it and make of it what they will.
