        Here's the situation.

        I have a Performer 1.2 program that displays several textured
billboards with varying transparency. The same executable displays
different behavior on different platforms:

Crimson w/RE -
        Modulates transparent textures correctly.

8-Cpu Onyx w/RE II & Crimson w/VGXT -
        The Top billboards OCCLUDE the deeper billboards
        even though the applicable GeoState transparency is
        ORed with PFTR_NO_OCCLUDE.

All systems running IRIX 5.2.

I'm still pretty new to Performer so I may be missing something.
I was pleased to get the desired result on one machine.
But what's different on the other platforms?

Do I need to apply a depth buffer setting of some kind?

I've tried all combinations of Transparency states.

Do you have any ideas?
