Hi DesuDeus, is the "no noise" one also done in Maxwell, or is it done in the C4D default renderer like I was asking about above?

Do you want to post the 3DM model file so that others could take a look at it and see if they can give you some tips about it?

Maybe Maxwell in particular is sensitive to something.

Do you have the normals tag in place when you are doing your renderer? Have you possibly done any kind of editing of the geometry that might invalidate the normals tag?
