Normal Map Issue Maya2016

Mauricio_Nieto

Hey guys, so I've been working on a project and did the classic Zbrush Normal Map baking workflow. I've tried the GoZ and manualy exporting and connecting the normal map, and 1) it shows some weird ring like artifacts in areas that should be smooth, I know there are issues on the dented bits, but the same map kind of works on Mari and Max, I've checked other threats here, and I've played around with the filtering type in the shader node, with the Color Space, Color Gain and Offset with no result. 
Please help!
Ohhhh and I can't seem to render in Mental Ray. 

Thanks in advance, hope anyone could shed some light on the matter.

Set the bump2d node's "Use as" option of your material (in the Attribute Editor) from Bump to Tangent Space Normals.

Thanks for the quick reply, the image from maya has the bump2d node as tangent space normals
