Even on surface shaders I get these black dots.
I only got rid of them by making a scene from scratch and importing the old scene into the new scene, however this is a less than ideal solution since I have to reapply all shaders. I want to know what causes this.
Another problem I'm having with the same scene (even the new/imported one) is all of the sudden the scene takes longer then normal to render, about 3 times what it should take even though it's just type with a HDR lookup sphere and a blurred version of it linked for final gather. Settings are what I normally use with no problems. The only "complicated" thing in the scene is reflection of the type. And even though it`s taking long I'm still getting unacceptable amount of noise. I'm new to mental ray but this type of stuff makes me think I should stick to vray. Hopefully some blessed soul can help me out here.
