Remember to save the obj from UVMapper, or the colours will end up in strange places :o) And of course you need to save the template too. Then load the NEW obj into Poser, I usually name my stuff mouseUV (or something similar) to distingusih them from the non mapped version. Of course you can also choose to overwrite. I usually save as a new version though. I don't know your modeling skills, though looking at that mouse they're not bad at all. What I was thinking was that it just needed a little wind-up key and some small wheels underneath :o) then it would go from "very nice" to PERFECT ;o)

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
