Is there a tutorial on the Surface Tab settings somewhere (Iray)?

I really try to understand how the shader settings in Iray work. As far as I understand, they can follow the specular or metallic workflow.

I'm especially interested in Skin settings. Are there any tutorials or further information about that? What i found so far is this
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/referenceguide/interface/panes/surfaces/shaders/iray_uber_shader/shader_general_concepts/start
I assume that the PAs have a lot more information.

I really try to understand which bitmaps control, which effect, as I want to transfer the bitmaps and settings to Cycles and Vray.

I generally just go here when I want to check on things. Look at the section you are interested in and then go to DAZ Studio and move sliders about to see what affect they have.

Thanks to both of you. I did a deep dive in the theory of different render engines especially looked at the alShader that comes with Vray. As I have a lot of Daz Assets, I really tried to understand how the maps are used in Iray and why specific settings are used.

There is a lot of information about metallic and specular workflow available. The Substance pages also provide some information about maps for these workflows. Most people seemed to be focused on maps for Unreal and Unity though. You get some information about Arnold and Cycles, but Iray is really missing.

I'll have a look at Sickleyields information. If anyone can provide further information, I'd love to hear it.

If anyone is interested,

I got a pointer to this thread, which contains a huge amount of information (over 90 pages). It will take some time to go through that.
