Complex UV Layout in Maya
Over the last couple of years UV layout in Maya has changed for the better. In this course we're going to be taking a look at some of those changes as we UV map an entire character

Yes I| did, was with a displacement but I didnt need that. The normal map is doing something but not a lot. Could be a setting in zbrush that I am missing...........dave
Edit: I think I fixed it, went into zbrush turned of the displacement then exported it, working fine????????????????

If it's about a normal map, Maya's normal map node doesn't work very well in my opinion. There's a great one from Jan Sandström (Pixero) for mental ray (and software for some versions) that you can find here: https://www.pixero.com/downloads_mr.html under "JS_Normalmapper and JS_EdgeDisplacer 1.2.2"
Give that a try.
Imagination is more important than knowledge.

Original I had a displacement and a normal map but the normal map was not comming through. The model comes back from zbrush a lot larger in scale than the I exported to zbrush? Some of the original settings were for the displacement map.
Smoothing on and 32 bit
For the normal map.
Tangant and smoothing on I think might have had adaptive on?
Blur set to 8
To get the normel to work I turned of displacement in zbrush norms set to tangant adaptive and smoothing on.......this worked but would like to understand why dis and nors would not work together thanks nextdesign have downloaded the node will have a look at it after I can fadom this out...........dave

First export the model from the export options box at the bottom right of the menu. turn off grp and turn on MRG. leave scale at 1. Export. Try the maps now. Scale is and always will be an issue in Maya.
Adaptive is fine for now too....
also can you show me yor alpha gain settings etc for the dis map.
then we can move on. We'll do a process of elimination. Im at work but with ZB here so will do what I can to help until this evening

Done the settings you suggested exported with dis map and norm map still the normal map is not comming through in mantal ray.
for the displacement Alpha gain is 1.219 and Alpha offset is -0.609
