Ok... working on a scene here, but I have a few problems with my render I dont understand how to fix..

Supposed to be a silver Chalace on a table with a gem leaning on it at the moment, when I turn on raytracing, I get wierd artifacts on the goblet, its supposed to be smooth, and i can see thru the middle of the goblet to the center section...

I know I need to turn off reflections on the wood table, I can figure that one out...

any other help on rendering problems would be helpful. =)

thanks

Steven
