Troubleshooting Normal Bump Maps 153
Raising and scaling the up per end of the projection cage.

With the corrected cage, the upper indentation appears
correctly in the normal bump map.
Tip: In situtations like this, another solution can be
to use Break on the vertices in the region of the
low-resolution object where detail is missing f rom
the map. This increases the number of vertices
in the cage, and reduces the chances of geometry
being missed. If you use this method, it is likely
you will need to make further adjustments to the
projection cage, as well.
