Just a quick check, are you using shade.rel.sh on a lat/lon projection?

If so the script produces terrible results because it assumes x, y and z 
are in the same scale.  I have modified the script to scale 
appropriately when a scale command line option is given, I can send you 
a copy, if this is your problem.
