The entire mesh, or individual vertices and edges may be moved whereever you want them. You can select any combination of vertecies, edges and whole polygons. I can't compare it to UVmapper pro, just UVmapper. As compared the regular UVmapper, IMHO, it's much, much easier to use. (But then again, my parents dropped me a lot on my head when I was a baby...) As with UVmapper, you can move and adjust meshes over the texture maps so layouts for Poser figures is easily accomplished. Now it's just the whole Poser import thing... With the press releases on Eovia's site, I'm cautiously optimistic about the future. I do a lot with aircraft meshes so this feature is outstanding for aligning texture maps with those kind of parts too. At any rate, it's much better than what Carrara had internaly for mapping before nothing.
