Thanks, Olaf. I saw jonwill's stuff before asking you and he uses the w3d_file.h that was included in the first Renegade Public Tools (the removed that in the second version). I originally thought he wrote that file and I was trying to get an official documentation about it, but now I know it was really an official file from Westwood Studios and it's the best thing I can find around.
