There are several far better renderers, and far better Carrara renderers, on this forum than me.

However, as I really am with nothing better to do than be enjoying new challenges, and have a history with Still Imagery in Carrara going back to V2.1 (Now 7), I can be of some help probably.

Quite happy to develop a direct "Help Me" e-mail connection if of value to anyone.

PM me.
