Black is "red=green=blue=0". Also, with curved tails of parts more complicated than plain cylinders like an animal's tail (corrugated breathing tubes, flat backpack straps), they sometimes neck off when posed, and come back to correct when moved a bit. I suspect that here and there in Poser there are arithmetic errors (INF = infinity = divide by zero), NaN = not-a-number = indefinite = 0/0 ), arcsin(x) if x*x>1, sqrt(-ve) etc, which caused crashes until some programmer whip-driven by some silly deadline quickly kludged them away by trapping the exception and setting the offending value to zero, regardless of what it should have been. RELEASE THE SOURCE FORMS OF POSER AND BRYCE, so we all can help to look for causes of bugs as is with JPG and the Gnu software. They say that some devils take the forms of goats; likewise here: the INF-amous NaN-nygoat may be the cause of these bugs :-) .
