Subsurface scattering?

With GhShaderNodes you can already use the Principled BSDF.

The component works as it should. Subsurface takes a number [0.0..1.0] (from fully off to fully enabled). Subsurface Radius takes a vector \overrightarrow{v}, but a color will do to. The constituents of \overrightarrow{v} each control how much the Subsurface Color gets applied essentially, again each with a domain of [0.0..1.0]. Subsurface Color takes just a color (but a vector will do, too). [image] principled_sample.3dm (81.1 KB) principled_sample.gh (16.5 KB) [image]

In the future we’ll no doubt have materials that utilize this automatically.
