First, sorry for the cross post, but I am desperate on this one!
There is a bug report out for this:
Report Reference ID: imiyqixx
RB3D - Nvidia display problems with alpha transparency
There's no such thing as an "Nvidia Voodoo3" so that report makes
little sense. The description of the visual artifacts is also lacking
detail; a 3DMF model that shows the problem would definitely help. I
have an Nvidia Geforce3 in my current Mac and could easily verify if
this is a genuine problem (though I've never seen anything remotely
like this) but if that user had a 3Dfx Voodoo3 card then there's a
whole mess of new variables that come into play. I had a Voodoo3 in
my previous Mac, and it wasn't quite plug-n-play. In fact, the reason
I got into 3D programming in the first place was to get the Mac port
of GLQuake working properly on my buggy Voodoo card...
Actually, what I am REALLY trying to do is display pictures using
AddShapePictureWithMask. I consistently get white backgrounds.
Are these objects lit? By default you'll get a specular highlight
across the entire face for lit surfaces. You can turn this off with
declares - check this recent thread for more details:

msg00278.html> Using Nullshader = True is easier if you don't require
the surfaces to be lit.
Has anyone found a workaround for this? What's the hold up getting
it fixed?
If this only happens inside QD3D/RAVE in Classic then there's no hope
in seeing a fix - i.e. Apple ain't gonna fix it. For what it's worth,
I get a lot of rendering errors with QD3D on my GeForce3 card. Some
of the problems seem to be in the RAVE compatibility layer for Nvidia
hardware, so I find it's best to use Carbon Quesa on OS 9 to force a
direct-to-OpenGL path instead of going through RAVE.
No this is OS X.
That report was for QD3D/Classic, so I assumed that was the same issue
you were seeing. It's almost certainly an unrelated problem on OS X...
The label Object3D is all white (except for the letters, obviously)
and you can only see the indicator state object if I turn off the
label. On WinXP it's even more interesting. From the top left corner
to the top right corner to the bottom right corner (triangle) the
label is displayed. The opposite half has the indicator images!
Is it drawing the wrong texture on half of the label or can you see
what's "underneath" the label? It may simply be clipping the geometry
below it (screenshots would help!)
Frank.
