Black and multi color dots need help.

[negronegrous]

Hello everyone, I don't know where should I introduce myself so here I am my name is Martín I'm an architect from Argentina. I want to learn from this great community and share my experiences too.

 

I'm just having this issue using 3Ds Max 2013 and Vray 2.30.01. All the materials are vray mat and lights are a mix of vray lights, vray sun and ray traced omnis. Sometimes when I increase light cache subdivs everything gets burn. :confused:

 

This is a low quality 1000*500 pixel fixed sampler and no filter test image.

 

Do you have any idea of what could be doing this?

 

Thanks!
