Sorry for the late response,haven't been online earlier.
Glad you found the solution Hannes.I didn't use the displ map
at all,cause I used the decimated version and knew it needs no
additional map,which is meant for the level 2 and 3 meshes only.
Just in case,here is what I did:the model loads without internal
shader(s) just a red parts
shader.So I connected a default shader
to its input,loaded the color map and set the diffuse colour to 1.
Loaded the spec map (reflectivity tab).
Then loaded the depth map in the translucency image slot and
set the translucency color to a red tending to orange.
Set the translucency value to 6 (no joke).
That's all.
Don't have an idea at the moment why you need those high values.
As for testing with a less real model,would a non textured make human
figure be sufficient? Otherwise I/we would need another free model
for that purpose.Any recommendations?
