Iray Surfaces And What They MeanI've updated and corrected this article based on DAZ's documentation. You should read that if you want more information. This will continue to be more of a "plain talk" breakdown.More Like This
Let us begin with the different types of shaders from the "Base Mixing" dropdown at the top. Choosing one of these will hide or gray out some options and reveal others.
The Iray shader behaves as though it has three layers: The "base" layer, the "metallic flakes" layer on top of that, and the "top coat layer" on top of that.
