Ugh... it seems that the materials for the outfit, unlike in the first export with the previous exporter, were skipped over and only the preview settings were applied. Before, it actually wrote out the textures and materials for everything that was secondary to the main figure. Hair looks fine. lol

Really odd behavior... I'm not sure I could be of any help, but I'll poke around the scripts to isolate where things are going odd. No promises though...
