There are a couple simple acid tests that Cararra's new SSS could be put to - for instance, render a SSS object, with another object inside it (like the bone within a finger) and see if it occludes the translucency. And I'd love to know if the scattered light will illuminate other objects. Oh, and hi - this is my first post in these forums, though I've followed them for some time. If I'm feeling crazy, I may even upload some artwork to my gallery someday. :)
