Different RGB Levels On Every Render

[pixela]

After I make a full render of the scene, for tweaking certain materials, I make partial renders when the full render is on VFB. I get a different RGB levels for each render- even without changing anything.

I am on Vray 2.10.01

Can you show some images? If you are using the light cache for secondary GI with low subdivs, then this is normal - a region render computes less paths for the light cache, so the solution may not be fully converged.
