Here are some shader tests done in Maya with Vray. I've never had much success with using the sss2 shader, lack of spec control and normals/bumps looking weak and soft. I'm using a blend/layered material made of two materials. One is shinny wet translucent (SSS2) the other a standard Vray material. I painted a mask in zbrush to blend the two materials as I want them. The sub surface material is strongest under the tentacles / webbing while the "solid" material is strongest on the body and head.
