We need to get a sticky up explaining how to make a fast render setup. Renders are much clearer then screen grabs as long as they are done right and not the default dk grey lambert shader against a black background lol.

You don't need any lighting at all. Just a plane with edges pulled up and beveled for a sight wall.

Then set environment light to light grey.

Then set mental ray to production fine trace, turn on final gather and that is about it. I think I may have gone through the set up in one of the recent videos I did on cutting holes in cylinders.
