somebody will hafta try a normal map in poser 8 or later to see if there's edge fall-off and which
normal deflection is associated with r, g, and b.  links to two free normal map generators were
posted in carrara forum, but they apparently don't know if a normal map has the same edge
fall-off as a bump map.  meaning a bump map doesn't cause apparent displacement (on render)
of polygons whose normal is at right angle (on edge) to camera view.

some reasons for switching to poser 8 (OS X):

• faster
• more stable
• IDL
• exposure control
