Well... It seems that the .FBX downloads were very misleading. The Wavefront OBJ (and, presumably, the Maya) file was actually a butterfly model. Though, obviously, the model in that file is not rigged because the format does not support that. But the .FBX downloads (both of which seem identical, BTW) do not contain a butterfly model. Instead, they contain a model of a young boy, which is rigged.
Please, can somebody tell me what the two ".xgip" files are for inside the .FBX format downloads? I see a "cabelo.xgip" and "sobrancelha.xgip" file inside. But even the File-extensions (dot) org site does not have an entry on the ".xgip" file format. Even GOOGLE search refuses to turn up more than 3 results for ".xgip" and none seem relevant! What are these?
