The figure is showing bare spots because the blHipNoGen.obj still has its existing mapping. I've overlayed the with gen, (green) and gen only, (red+white) maps as the background for comparison. You will probably find it easier to remap the no gen hip to a clear part of the map rather than have it overlapping as it now stands. Hope this helps rather than confuzzles :) [](http://www.philc.net)
