Maya normal map channel creating rough surface in render

Dippndots · Jul 2013

As you can see by the pictures below, my normal map is being rendered incorrectly (using the maya software renderer). The red area shouldnt have that noisey texture. The material bump node is set to Tangent Space Normals so im not sure whats going wrong. I baked the normals in Modo.

Any idea whats causing this?

My guess would be you have some crazy node associations happening in the Hypershade. Have you tried applying your normal map from a freshly created material?

Still happening unfortunately

normal maps are not supported in software renderer, Maya renders them as bump maps instead in software render.

you have to render using mental ray.

Thanks MM, not sure how I didnt notice that...
