Normal map problems

I can't seem to create a new thread in the suppport forum so that is why I am posting here.

When I load in a normal map onto my model I get some odd affects.

Without Normal:

With Normal:

I created the map in Zbrush:

The model is to scale and the normal is set to bool smoothing.

Can anybody help me out?

You need a normal map in tangent space, maybe "Switch R+G", i don“t use Zbrush.

Thanks for your reply mib, when I turn tangent on Zbrush generates a rather flat map in comparison to my previous one. I tried it anyway and it works :)

The other problem I am experiencing is when I want to import other parts of the head (eyes) the UVs go crazy.

Only head mesh in OBJ with diffuse and bump applied:

Reimport the obj with eyes. The eyes both have separate materials applied to them:

What's going on?

Fixed it!

I was transfering the model from Zbrush to Max to try and fix it and while I exported it with Maya settings I got the UV madness.

If I exported it using XSI settings the scaling was fixed:
