Weird!

So, before I got on with trying to get my dragon into Poser, I had to go back and get all the other body parts and merge them while retaining their VUs. (Eyeballs, jaws, eyelids, claws, etc.) It kept the UV's but the textures are no longer assigned to the tools. I think that's fine, because the UVs are there and I can export the textures from the un-merged versions and maybe re-assign them?

In case the "merged tools to one obj" version had reordered verts, breaking the textures from fitting the UV's, I have also exported the individual tools as obj, with their UV's , textures, and verts in the order the textures "know." That way I can hopefully copy and apply them to the merged versions in UV Mapper...? Not really all that much extra work, but maybe not necessary...

So, OKAY, that's not even the problem I'm having, lol. What went down is, I brought the merged model into UV Mapper just to check if the UV's did in-fact survive, (since I couldn't check seams in ZB this time I merged, for whatever reason) and, yes they did make it, but the odd thing is... this time in UV Mapper, I CAN re-name the groups, it's not grayed out. Another behavior has also changed. When I select a group everything else disappears. Maybe it's in some different viewing mode, idk, since it's not showing me selected verts as highlighted like before. I selected everything and welded all vertices. It reported 0 verts removed, so I guess there was no duplicates, and it's an intact object?
