Uma,
I've spent this afternoon chasing the problem with Appearances that I
described earlier and trying to come up with a test case for you. I started
with trying to modify the demo AppearanceTest example, and I couldn't
reproduce the bug... but I could still reproduce the problem in my code.
So I factored out most of my code and came up with a shortish example
(attached). In my code I create a Box primitive, and then replace the
coordinates/colors/texture coordinates and normals of the left face. This
seems to be causing the problem under 1.2B1 (worked fine in 1.1.x).
If you comment out the code to modify the left face then the
ColoringAttributes are used for all the faces of the Box. However, if you
modify the left face, the non-modified faces of the Box are black and the
ColoringAttributes is ignored. I imagine this is also the cause of the
problem with Transparency that I described (though I have not verified
this).
Very strange. Please keep me posted.
Sincerely,
Daniel
