Is there a specific order the mix materials are processed in? I mean is the first material input treated as the top layer and the second one as the bottom layer? So that only light making it through the top layer gets to the bottom layer etc?

Thanks!

Hi Cybernoid,
No, it is not a one then the other type thing.
It's driven by probability. A mix amount of 0.5 means a 50/50 chance that a ray will "choose" that material when bouncing around the scene. The combined results of all rays are what you end up seeing. So it's more like compositing the two.

Thanks
Chris.

Ah ok so it's like interleaving them in place. In which case I vote for proper layered materials as a feature request please! (As shelling things isn't quite practical for the most part!)

So even though some of the skin materials are quite good they won't be able to become really exceptional without proper layered material support.
