    What version of the viewer are you using? Viewer-1.23 redefined the 
fourth channel of baked textures to be "alpha mask" instead of "bump 
map". If you load old baked textures that generated a fourth channel 
intending it to be a bump map, and use it as a baked texture for a 1.23+ 
viewer, the viewer will incorrectly interpret the fourth channel as an 
alpha mask, resulting in images like you included in your email.

Were the avatars on the sim a mix of 2.0 and 1.22 (or previous) versions 
by any chance?
