If you can do the dynamic billboards in your own code with
pfGeodes, that is probably safest. However, be aware that if
you run multipipe, you'll probably need to keep multiple copies
to avoid data collisions.

This is what billboards do internally and why billboards keep
multiple copies of the geosets attributes which depend on the
viewing position. Basically, you need to tell the pfBillboard
that it needs to go back and reevaluate the application
provided geosets. The least expensive way of doing this is to
reset the pfBillboardAxis.
