Hello.

Thank you for purchasing Reality.

I strongly suggest that you read the Reality User's Guide (RUG). Without the necessary information you might end up spending a lot of time looking for information that is right at your fingertips. Twenty minutes with the RUG will literally save you hours, if not days, of trial and error. The part about LuxRender never stopping, for example, is right at the beginning of the guide.

Hope this helps.

Paolo
