Need some advice with Vray settings ...

Hi,

I am have been using Vray (still a novice though)for quite some time now. Recently my office upgraded to Vray for sketchup 2.0. I am getting some strange render noise at the ceiling. Didnt have this issue with 1.49. Can someone please suggest what might be causing this ? Please see attached render with the noise at the ceilig, also attached are few screenshots of the Vray setting. Thank you for looking into it. Appreciate any help and suggestions.

Thanks

What are your environment settings? I would think its a light leak issue. Have you tried to model something above you ceiling to close it in and prevent direct light from hitting it?

Environment setting are left as default. I have a 12" slab above the ceiling. Do you think i should modelling a box (of floor height) on top will help solve this problem ? I tried tweaking the IR Map setting but didnt help. Thanks for looking into it. I will try adding a box on top and give it a shot tomorrow.

My last question would be which version of 2.0 do you have? Is is the very latest?

Hi valerostudio,

I got better results with AO turned off but still there are strange spots on the ceiling and lost the depth in the rendering with AO turned off. Can you please suggest what would be a best starting point for AO setting in a rendering which have fine moldings ? or a way around it ?

Thank you.
