At first, I have no geometry on the scene. Totally void. I then
add an empty group which has no geometry, but has a pre and post
draw function callback. I use this for explosions. Although, I will
probably never use it without other geometry on the scene, I am
curious as to why the functions callbacks are never called without
other geometry on the scene? Once I load a model or something, it
works, but 1 or more explosions and nothing happens. Of course,
the cull and draw masks are set correctly. Any ideas?
If needed I can post some code, but that essentially sums it up.

Thanks.
