Black backfaces

[SamPage]

Continuing the discussion from Rendered viewport is black:

@SamPage

I’m not sure this is the same issue or something else, but what color is the Ambient color in the display modes you are seeing this in, and what happens if you change the ambient color? Over here, it seems backfaces are always displaying in the ambient color.

As it doesn’t seem like this is what Jørgen is seeing, I thought I would start a new thread. Over here, if Use advanced GPU lighting is off, backfaces seem to pick up the Ambient color, which is often black, leading to black back faces. Setting use advanced GPU lighting will have the backfaces shading correctly, but on heavier models they will drop back out when orbiting the view. Example attached.
