Could you show node setup for material and volume for that skin?

Glossy Translucent in fact is not translucent. I suggest renaming it to something like 'Glossy 100% Scattering'.

And matte to "100% Uniform Diffuse Reflection"?

:D
Matte is fine, it is matte after all.
Glossy translucent is not. It's name is misleading, it's behaviour is unrealistic. It refuse to obey volume settings; mixing it with glass results in funny, well, result.

Here you go wasd... My LuxCore Skin settings:

The texture always darkens.
Good Luck.

Arnold's setting for Random Walk. Really easy to understand. Weight, Color, Radius, Scale.

Edit: When looking for Arnold random walk tutorials I ran across the crab image. It was all faked. He mixed an ambient occlusion node with a color node + the random walk.

Hi,

So I'm curious. I know that light cache for direct light is already being worked on. But I wonder if "part II" the indirect light cache is to be done next? Or will we wait longer for that one?

You mean from the system file browser into the node editor?
I'd like that too, but Blender does not allow addons to handle drop events. https://developer.blender.org/T39625

Maybe I can hack something together with an external UI system like Qt though:

In the poll there is "new glossy with multiple scattering ggx" Can this be added to glass material as well? So that we don't get darker glass with increasing roughness?

Oh, only 4 years since then. Maybe a little later. It took only 24 years for them to get cube defined not by radius, but by edge length and sphere (haha) not by "size", but like it used to be for cube, by radius. Wait... They didn't do it yet.
