Thanks everyone for all your help. Here is what I have tried and what has happened.
First I saved the Mil cat as an obj. file and tried to import it into Scuptris (which is rather cool by the way, except for this model). When I tried to import it, it failed with a Mesh error ” Too many triangles connected to an edge (max2)”. I have no idea what to do with that. So just to try something else, I did the same thing with the Genesis model and it loaded fine. errrr!
Then I tried “Send to Hexagon” from Daz Studio to see if that would work and it loads fine and looks good. I just can’t get it to work correctly in UV & Paint.
I am guessing that I don’t understand how to create the right kind of projection before trying to paint.
Did I mention that I am a rookie at this, but after watching a good tutorial on how to use UV & Paint in Hexagon, it didn’t look that difficult. Hexagon has more than adequate paint features for what I need to do.
