3ds Max :: Normal Map Not Rendering Details Properly

I'm trying to project a normal map from a high poly model onto its low-poly version but I'm having some problems.

I modeled some details on the high-poly model as you can see in FIG.1.

The details all have the same depth and everything as can be seen on FIG.2

But yet when the normal map renders, the detail loses depth the further they go from the center and the squarish detail at the bottom doesn't even show up at all. (FIG.3)

I tried pretty much everything I could think of to fix this, but nothing works.
