Unhappy Normal map display issue (viewport vs render)

hey guys ..

I can't seem to get my normal map to display properly at render time, was wondering if anyone might have some insight on the problem.

My set up: (Using Mental Ray Renderer)

I used a red and green picture as a mask, and fed in two separate normal maps that gets combined with a layered texture, setting blend mode for both to be "over"

In viewport 2.0 it looks okay;

But when I render it , it just looks really flat, I suspect it could be a lighting issue too but I can't get it to work:

If I changed the blend mode to anything other than "over" I tend to get a large amount of cracks but it looks a bit more 3D:

Any help would be appreciated!

For some reason it really bothers me that you fail to mention what renderer you're using.

Have you tried combining those two normal maps into one, and getting rid of the mask/layered texture node altogether? I'm not certain that's the problem but I think it's worth a shot.
