Robyn, as I understand it, the mathematics for subsurface scattering was in a published academic paper, and Blender and Poser both implemented it, probably with some variation. The logical components and even the presets are very similar indeed. Blender had SSS before Poser did, but it took Poser 9 to even make me aware that there was such a thing. And I now have a new machine that lets me do test renders quite quickly. The render above took 1 minute 43 seconds.

The interface for creating material shaders is different, but the principles are the same. I am figuring out the nodes in Blender, but slowly.
