Hi! FBX importer dosen't import uv-maps correctly if uv-map count is 2 or more. The problem is that fbx importer when it is creating those maps it dosen't give a count that
when calling mesh.uv_layers.new method, blender will will create automaticly uv-data for mesh. I was able to make this work if I after uv_layers.new will set all uv location
to (0,0) then leave fbx importer addon to continue its work.

You can find this code from import.fbx.py and line 1012. Adding last 4 lines will make importer to work with multiply uv-sets.

   uv_lay = mesh.uv_layers.new(name=fbx_layer_name)

            if uv_lay is None:
                print("Failed to add {%r %r} UVLayer to %r (probably too many of them?)"
                      "" % (layer_id, fbx_layer_name, mesh.name))
                continue

            blen_data = mesh.uv_layers[-1].data
            for u in blen_data:
                u.uv[0] = 0
                u.uv[1] = 0

Thanks for the suggestion, but will rather update API so that we can generate 'NULL' UVlayers, will be much more efficient. ;)
