If you disable "visible to diffuse", but leave "visible to specular" enabled, you dont see any reflection at all
Roeland, here is an orbx to demonstrate what I was talking about with this issue.
Load the orbx and start the render. Visible to specular is disabled, so we should not be seeing any reflection on the sphere, but we see this noise
If you select the "area light emitter material" group > emission, then disable "visible to diffuse, and enable "visible to specular", we should be seeing a black sphere with a bright specular reflection on it. Instead we see nothing.
If you select the "mat1" group and set the material roughness to 0, the coating reflection will show the expected reflection. This seems to be related to the issue with coating being affected by roughness and GI clamp.
