I seem to have a problem with some of my objects, they are very dark (see pic).
The shoulder plate on the left is using the same texture and shader as the one on the right, yet its much darker. I’m thinking something with normals?
I have fiddled around with the normals in Maya, but the model displays just fine in Maya, so I’m not sure if its a unity thing or what.
Any ideas?

In the fbx import settings, you could always try changing the normals from import to calculate.
Yeah I have them set to calculate with an angle of 90.
None Of the Import settings in unity are doing diddly 
Thanks though
Are the effected parts set to correctly receive lighting?
Try turning on backface culling in Maya, as without it the display isn’t representative of what you’ll see in-engine.

Im not sure exactly what you mean, I have looked at the material in both unity and maya and everything appears to be in order.
@cannon
Thanks for the advice, the normals appear inverted in maya however when viewed in unity they are dark. When I reverse them they appear correct in maya, but are inverted in unity
Fairly frustrating =/
