Originally I used the existing shirt, as you suggest. Changed the color, saved it to the clothing library with a new name -- very simple. I had thought that all I'd need to do was map a logo onto it by grouping some polygons on the shirt's chest and assigning them a "texture" comprised of the logo. No such luck! That led me to UVMapper. I exported an OBJ file out of Poser for UVMapper, and from UVMapper exported both an object file and a texture map -- since I didn't want to overwrite the original. So now, as I described above, I have a new shirt with the logo the way I want it -- but it's not a piece of clothing: it's a prop. I can assign various Mike body parts as the new shirt's parent, but for some reason the shirt arms won't move -- just the abdomen and chest. So I figure I am missing something obvious. I can render out a few images to show you what I mean, if you'd like me to.
