Normal Maps made in Mudbox

jaden

I seem to be having some trouble with the bump maps I get from Mudbox. Whenever I put them into 3ds max (version 6) it always shows just a few striations in the mesh, but no actual features from the high-poly model. Any help is appreciated.

EDIT: I have the normal maps working now, but there are a lot of dark spots or dark gradients.

Yes, i'm new to this,
Jaden.
