displacement maps + skin shader ?

[Lamster]

Hmm, first off I don't mean any offence at all. Just trying to cover all possibilities first, starting from the most obvious. If you don't know that you're supposed to connect your displacement map to your Shader's Shading Group eg. blinn1sg node then please try it out.

d'oh, sorry. thx

although now I'm getting blocky results on my geometry with the displacement map applied :

is the only way to fix this increasing the poly count of my head ?

is there some smoothing option I can use ?

[Lamster]

Ermm.. I think you might want to fix the mesh topology of the head itself first before you go into any smoothing. The blockiness that I see in your render in my opinion, largely due to the way your head topology is laid out.

You can't just throw a displacement map onto your shader and expect everything to be fine and dandy either. Now I've not had much success working with Maya Displacement, and I've got a few more grey hairs with Mental Ray Displacement. You'll need to take a look around Maya Help and maybe some internet tutorials on Maya displacement in order to get things to look right.

Take a look at this thread in order to see some good examples of head meshes.

It's very long, so take your time to skim through it. From the Last post would be a good idea.
