Have you considered setting BlendColor at the parent Group node and using one of

Thanks for your response.
No I havent considered this. I dont understand how it will accomplish what I'm
looking for. Can you elaborate? I'm looking for alpha, there's lots of
geometry in front of eaach other. Blending with a constant color wont simulate
transparency, if I'm understanding you correctly.
You should learn OpenGL, I suggest the red book (the programming guide). The
(IMO more useful) blue book is available online:
http://www.opengl.org/sdk/docs/man/
...and some browsers even display the formulas correctly. :-(
GL_CONSTANT_ALPHA,GL_ONE_MINUS_CONSTANT_ALPHA are the blending coefficients
you'd typically use for this, they will reference the alpha from your (one)
BlendColor, but the rgb components will come from your (multiple) primitives.
