Thanks everybody. Very clear. I have been playing with the Carrara demo and finally got something useful out of it. It doesn't seem to like importing DXF files I've noticed but am hoping that is just limited to the demo. AI comes out perfect. Yesterday also downloaded Shader 8 demo. My lord that does seem complicated. See that there is a forum here for that program too, but nobody seems to use it. Anybody have any experience with that?
