Death stalks the toy rodent...

Thank you all very much for the replies. They have been very useful.

I gave UVMapper another try, and did manage to get reasonable-looking UV maps in planar and cylindrical mode, but they didn't wrap correctly. The colors weren't where they should be, and I have no clue why.

But I have gotten the material zones set. I was very confused, because Anim8or has a materials editor, but none of the files I exported kept the color info. Turns out that was because I was exporting them as OBJs. I guess you have to export in 3DS if you want to keep the color info. The 3DS imported into Poser fine, colors intact.

I will definitely check out that UVMapper tutorial. I doubt I'll ever be a great texturist; I was one of those kids who hating coloring books, and could never stay in the lines. :-) But I want to understand how it works, just as a matter of principle.
