This is the setting:
- I am working with multiple stencil planes in a Performer 1.2
application;
- I have some transparent objects (objects with material alpha < 1.0)
in the same scenes as the stencil ones;
- I also have some objects with textures containing alpha
components,
- I have antialiasing turned on (using multisampling on our
single-pipe Onyx RE2 with 2 RMs).
Whenever I use stencil planes and multisampling (using
mssize(8, 32, 8), for example), the objects with material alpha
no longer appear. However, textures with alpha components still
seem to render correctly. If I turn off stencilling, then the
transparent objects return, but, of course, my stencil stuff is
all messed up.
Should I be able to display transparent objects and make use of
one or more stencil planes at the same time? Do I need a greater
pixel depth than "medium"?
Could someone offer some suggestions? Thanks.
Glen.
