Dermis Mini: A Simplified, Fast-Turnaround Multi-Level Sss Principled Shader For Cycles
Help, my skin looks all grey and dark and weird!!
Cycles samples materials with multiple shaders strangely, sampling only one shader in the material at random each sample. This can be fixed by using Branched Path Tracing, which enables sampling of all shaders in a material on each sample, OR, if this is too slow, you can increase the brightness of the lighting in your scene by 3 to 5 times. This will give approximately the same results, but with harsher specular highlights, shadows, and other altered surface characteristics.
It is recommended to use Branched Path Tracing with this shader.
