Well after the last pass there is nothing left to draw, but I am resetting
things and this is not the problem.

Yes this is what I want, but how can I say from the channel draw call-back
to draw just these polygons, and then to draw them again for the second
pass, and then to draw everything else? pfDraw() just does the lot. I
can't even find out how to access the display list that the cull process has
created and passed on to the draw process.
The only thing I can think of is to have a second channel with a second
scene graph containing only those things that must be drawn twice. Does
this sound reasonable?

The what? Is this code available somewhere?
Thanks for the reply,
