What version of Maya/ MR?

Are you using complete, unlimited, educational version?

When you say you "send it to the batch editor", do you mean you run the batch render command or are you sending it to a render farm?

The background behind the character... is it 3d, an image plane, comped?

Are you using render layers?

Are you using render IBL?

What image format are you rendering to?

You results are very screwy so I'm just trying to get an idea of what you're doing.
