Here are 3 versions of the same close-up portrait with different skin-textures, unfortunately I neglected to take note of the light settings, so they're not quite consistent, but should still show the differences between the skin textures.

First one is the default "matte" as exported by LuxPose:

MakeNamedMaterial "Victoria4/1_SkinFace" "string type" ["matte"]

"texture Kd" ["Color_Mul_59"]

"texture bumpmap" ["Mul_21"]
