Hey Latexluv only thing I see is your line:

MakeNamedMaterial "Victoria4/2_SkinHead" "string type" ["matte"]

should maybe be:

MakeNamedMaterial "Victoria4/2_SkinHead" "string type" ["mattetranslucent"]

and I believe that the translucence comes from the Kt value which you don't seem
to have in your listing....
