I just recall you said you were using an ambient light a while back... that might be screwing up your maps, because bump maps for example don't work with ambient lights. Don't use an ambient light if you are.

Probably not, but it was probably causing your first render... sorry I skimmed some of the thread.

You need to check this training out done by Jay. It really answers all your questions about displacement, normal, cavity, diffuse overall technique setup in Maya. Even if you are not interested in the sss, it gives you an overall view and technique. You can skip the Zbrush map extraction since you are using mudbox, but it certainly helps you setup all your materials from Mudbox in Maya.

Maya-ZBrush Workflow
Skin Sculpting & PolyPainting in ZBrush
Displacement & Normal Maps in ZBrush
Cavity & Specular Maps in ZBrush
Texture Maps & Logos in Photoshop

Bump Maps for Cloth

Subsurface Scattering in Mental Ray

Hope that helps mate.

About your seems issues, you can open your displacement in Photoshop and paint that area over with gray, save and import it back. That's the quickest way to fix this issue you are having with the seem.

Dave: edge bleed is set to 2 and yes UVs are all in UV area I made sure to do that before i sent it to mudbox.

CGI: yea i'm going to pick up that tutorial next month when i get paid, been wanting to look at it for a while now. I'll try the greying in photoshop and see if it helps.

Can I suggest export the displacement map as a 16bit. Sometimes maya doesnt like 32 bit, dont ask why.

With the 16bit you can control its scale thru the color gain and offset until you are happy with the result. It may just be a setting thats causing it to burst at the seams literally.

With opening dismaps in Photoshop check that color management is off other wise you can screw the map up and it wont work properly.

saved as a 16bit looks a lot better now, those edges are kind of concerning though
