I’ve read several posts relating to blotchy renders and tried all the suggestions to solve the problem but in this case nothing is working. I’ve changed the Hsph subdivs/interp samples/min & max rates/Global subs multiplier/light’s subds/material’s subs/interpolation types & sample look ups and nothing is making any difference.
Is there anything I am missing or should be looking at changing in my scene to get a smooth render?
It’s a simple Vray material with a diffuse colour & low reflection-not rocket science. I have similar materials in the scene which have rendered perfectly but on the cornice it doesn’t want to play ball.
It seems to me like complanar faces, especially because the problem occurs only a this specific object - maybe the object is twice in the scene matching complanar or any modifier did cloning by accident?
Just a guess, but I’ve had issues with noise on sweeps with little or no segments. If that is the case for you add more vertical segments, and try that.
