MR SSS skin + car paint are rendered black in passes

[fearnight2000]

Hello.
Currently, the MR sss skin and car paint (there are probably more but these are the 2 i noticed) are rendered completely black in all the render passes (spec, diffuse, object or material id, etc).
Is there a way make these render correctly in the render passes

Thanks in advance.

Is there any environment map or Physical sun and sky in the scene to reflect?

In some scenes yes (for both the physical sun/sky and the environment map), in others no.
But i don't see how this is relevant, since even the mat or object id is black in the render passes.

Just trying to narrow down your scene setup as chrome and shiny/mirror materials need sumptin to reflect or they look black at times. Just like if you don't have the right render engine selected materials in editor can appear black, a lot of variables that are needed to be known to help. I only have Max up to 2010, but perhaps if you posted a simple scene that was causing you problems we could take a look.

Here is a simple test scene. You'll notice that both the materials are rendered black in all the render passes (actually only the diffuse pass works)

I couldn't attach the file here as the manage attachments window was empty.

Will look into the sites attachment window issue, don't have time at the moment to look at scene, will try to later.
