I’m trying to make a skin shader for a human character, but I’m experiencing a problem with the SSS. It seems to be showing small bits of green on the model. Below is an example of what I mean. Around the eyes and around the mouth is some green light being cast, but I don’t know where it’s coming from. Sorry about the low quality of the head model. I whipped it up in a few seconds just to show my problem.
It’s due to the algorithm that Cycles uses to calculate SSS.
You can mitigate though by mixing in multiple SSS shaders as well as a diffuse componet (optionally you might want to decrease the blue scattering distance a bit further to reduce it even more).
