I opened the mtl file that came with Ivy and this is all I saw: newmtl klinker map_Kd klinker.png I seems its simply re-directing it to use the png file for texture? Or am I missing something? I guess if you had a lot of different texture maps it would be helpful by directing them all to the proper surfaces so you wouldn't need to do it manually? (just guessing here). Well, thanks for the info.
