I built this model in Wings and ran it through UVMapper so I could make a texture map. It's for a nightime scene I'm working on. I wanted to texture and render it in Carrara. I admit I was intimidated about trying to set up my alpha map in Carrara because of all the "horror stories" I've read about at the DAZ forum, but a little tinkering got it to work right away.

The improved object import options in Carrara6.2 on make it very easy to import and texture models because you can import a model as different object groups. This makes it very easy to take a UVmapped and textured model and substitute Carrara shaders for some parts.
I get to love this app more and more all the time.
