Mec4d - These candles look awesome! Again (as per the other msg thread), I suspect you will get the effect regardless of the light positions...so it's kind of "fake translucency". Tunesy....definitely adding a small amount of translucent (or ambient) red to skin tones will improve human skin a heap. You just need to tune the amount of red depending on the amount of light in the scene. You you add lots of translunce, back the diffuse off a point or two. Mec4d - yes, the sss map is the key. The HyperReal kit uses both a V3 head and body sss maps to control where the ambient (translucent) and diffuse incidence effect gets applied. Makes a big difference. As for getting REAL sss....that is the quest. I think there are two possibilities.....1) Some tricks with specular. So far, experiments has been a total failure, but haven't given up yet, or 2) A phython script which analyses the lights in the scene and creates a lightball map (like a sphere) jpg (using the sss algorythms), which could then be plugged in to the ambient node.
