otaku, Seems the .uvs files for PC won't work on the Mac version of UVMapper. I haven't tried it myself (not till Monday, anyway), but "UVS MapDecoder" by MartinC from www.soft-rabbit.com is said to be able to use the PC versions. In any event, we've posted a Mac compatible version on the product page. It, however, only contains 1 .uvs file... as UVM (Mac) 0.2.9 doesn't support the inclusion of material group assignment. -Rob
