Vue's preview is definitely excellent, I reckon...

...and the Blender mat room looks good... thanks Wolf.

I don't know what Blender has in terms of material presets, within that nodes system, for metals, glass etc, of course?

That's surely where the maths starts to come into it?

Poser's mat room obviously has some SSS presets embedded into its nodes now, for the physical properties of things like Skimmed Milk.

I guess having presets for the material properties of metals or glass or plastic, etc. in the appropriate nodes... the kinds of things for which all the math nodes are currently required, as I understand it... might be a logical progression, in due course?
