Normal map won't appear on my model in MAYA (Solved)

I've just baked my high poly onto my low poly to get a normal map and I want to see it on the model so I can work on optomising and LOD

After applying the material it just won't show on the specific model but will show on others.


Model to the left is the problem asset. Object on the right is a standard box with the same material applied which works fine.


And here's the UV map perfectly lined up with the normals. Even if I move the UV's around nothing updates on the model. 

I know the normals work on the model because here they are applied in substance painter.

For the benefit of any people googling this, after some excessive fiddling I realised that I had 2 UV sets on the model, one of which had no UV's.. I copied over the UV map from the other one and now it all works.
