Vray 2.0 NOT Rendering!!

[GaboM5]

Hi everybody!

I have this recurrent problem. Vray get stuck at a certain point when rendering.
When I'm doing a test render everything its just fine. Very low res, low image, color mapping at Fixed or Subd. Light Cache at 500, Image size 600*400. Very low subd for materials, lights and shadows.

The problem seem to appear whenever it wants. Everything seems normal but suddenly, when im trying to render, vray does not get pass 5% at light cache. And just to get to that 5% progress, it took my PC over 2 hours. The only thing that i've noticed its that my CPU gets crazy, starts working at 100% load, then drops down to 14%, gets back to 80-90% and drops back again, so on and so forth.

This problem had happened already several times in the last few months, but just as it appears goes aways.

I have no idea what could be happening, every help would be really appreciated.

Thanks!!!!!

Do you have any materials with displacement? Try turning it off in the options menu and try again. Maybe that helps?
