Spring has (finally) arrived. Nice to be able to air out the apartment and go for walks in the park.

IRAY!!Herewith, some preliminary findings from my mad flailing at the new physically based render engine included as an option with DAZ Studio 4.8 Public Beta. Some of these are confirmed by Google, some purely by experiment this evening (Iray is Nvidia's, so it's existed since well before DAZ got hold of it, it's just not widespread yet).
My system specs on my main (not on this laptop I use for internet access):
Intel Core i7-5930K at 3.50 GhZ, 6 cores.
Installed memory: 64 gb
Graphics cards: 2x GTX 740, 2x GTX 980, all 4 gb cards; not in SLI.
For those who are worried, no, Iray is not mandatory, you can still use 3Delight from the Render Settings dropdown. This is important because:
1. You can use Iray with just the CPU, but not if you want to remain sane.
Iray wants graphics cards, and it wants CUDA cores, and it wants lots of them. I tried rendering with all four graphics cards checked, with just the CPU checked, and with both checked.
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.
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. It is possible to turn off the top two layers and not use their settings, but the ability to use them is a property this shader has that 3Delight did not. This makes using shaders made for Iray very important when rendering to get the best look in Iray!
