Every piece of clothing that I have converted, which has more than one surface, appears to lose its uv map and ends up with a single surface with some sort of borked uv map.

Edit: Actually it's more like the all surfaces and uvmaps merge into one. So if the object had multiple surfaces that all use the same image maps, then it looks fine. But if each original surface has it's own image map, then only the part of the combined surface which used the current image map looks ok, and the rest are all borked.

Also, it crashes daz a lot on exit.
