Hello,
i do some renders for my client and for last one something unexpected happened. Could anyone tell me what is wrong?
Shader for carpet is simple diffuse. I have no idea what goes wrong… help 
Just guessing wildly here (because: no .blend file for review), but is it possible that “clamp direct” is at a very low value (perhaps even <1) and “clamp indirect” (= e. g. reflection of light) is not?
ITS possibly, but my sets are 3 and 2,5 for direct and indirect… Checked erlier by disable clumps and no effect. But i will try again tommorow. Did not attache blend beacuse it is quite big, but thanks for answer
