[osg-users] Transparent models

[Robert Balfour]

I have two transparent walls (alpha = 0.5) against an opaque surface. 
Initially everything looks good - you can see the second wall thru the
first (closer) wall, and can make out the opaque surface thru both of
them.

But when I move the first wall very close to the second wall (but still
completely in front of it), pieces of the second transparent wall begin
to disappear behind the first wall.  The opaque surface remains visible.

What could be causing this effect?  I have both walls assigned to a
transparent renderbin.  Even putting them in different renderbins didn't
seem to have any effect?

Thanks.

Bob.
