Have you guys ever hused Kerkythea to render your model? Do you know of any sites (other then the Kerkythea site itself) with a database of "ready to go" materials?

Thanks for the such quick response. That seem to have work. I'll keep my fingers crossed. I have a NVIDIA Quadro FX 550. I'm just wondering, what does check that off change or do to the model?

I have this annoying problem. My sketchup completely freezes every 5 mins or after 10 - 15 clicks of the mouse. It freezes for about 15 seconds then comes back. At first i thought it was autosaving but i changed that setting to save every 20 mins and it still freezes. It doesn't do this when first opening the program but after 30 mins or so of drawing it starts to do this. And the things that im working on most of the time aren't that advanced or complex. I was just wondering if anyone else is having the same problem or knows how to fix it?
