Hi,
What's the common use of a LuxCoreRender material's Absorption functions? It seems that it only changes the surface color, or can you also achieve some SSS effect with it, as opposed to adding a Volume node?
Thanks!

Re: Use for material's absorption color
It simulates absorption in the glossy coating, which means it's angle-dependent: the shallower the angle between camera and surface, the stronger the effect. I think I've seen this effect in pottery glaze, but I'm not totally sure. It can also be used for car paint.
It does not compute any SSS.

Thanks for the clarification! So if I understand it correctly absorption on a material level is more like a coating, not sub-surface absorption for a SSS / translucency effect. A volume node is needed for that.

Yes, in Lux, materials always describe only the surface, the inside of an object is defined by the volume definition.MetinSeven wrote: ↑Mon Jul 27, 2020 10:00 am Thanks for the clarification!
