Thanks for looking.

It looks like your material/texture is missing a normal map and specular map. Create them and reconvert the materials through asset manager.
If you have a normal and spec map then make sure the model is above 0,0,0 in Maya before exporting. If the models origin is offset then it may be getting lighting from another area in your map.
If its above 0,0,0 then try exporting as obj from tomxmodel utils and reimporting through asset manager.
