hi.

i've run into a perplexing problem when porting some code from an IR2
running GL Performer 2.2, OGL Volumizer 1.2 to an Octane2 V12 running
OGL Performer 2.5.
i can't get my Performer wrapped, OGL Volumizer texturing w/alpha to
display properly. i can only get correct transparency if i lie to Volumizer
about the correct internal data format and use glBlendEquationEXT(GL_MAX_EXT).
of course, this won't do.
interestingly, though, my old 2.2 binaries also give me bad transparency
on the V12, which makes me suspect some hardware nuance?

was there anything common that people porting up to 2.5 encountered that
rings any bells with my description?
or a common IR2/V12 graphics issue relating to texturing/alpha blending?

thanks.

ps. yes. i've posted to the Volumizer list. we've not been able to
     solve it there, yet.
