There is a large part of this VW bus with the same colour/texture finish. Some of it does not respond within Mazwell and is the dark region you can see here. Preliminary right now and I do not see it getting any better but there is a serious need for pdf in depth tutorials rather than the knowledge base which just takes one around the houses with pointless link after pointless link. Actually, I do feel entitled to criticise.

I tried uploading the render scene but it failed, cannot edit my post so I'll try again.

What does "not respond" mean and what is the "dark area"?

Without describing the problem or putting the MXS up on Dropbox or similar, it is hard to say anything meaningful at all.
