One Caveat.  NMake sure you have a fairly powerful machine.  Carrara can be a huge memory hog when you start using Poser content and/or start playing with multiple light sources and a lot of transparent, reflective, refractive or complex items.

Quote - Thanks for the replies. You all were a big help.
I did try the demo and I did have V4 at one time. I think I gave it up because it crashed a lot.
I think I just need to stay with Carrara and really try to learn it.

Thanks for your help.
