Hi,

I want to illuminate my scene with more than 8 lights. I achieve this
by attaching lights to specified parts of the scene with pre and post
traversal callbacks (pfNodeTravFuncs() for the draw traversal).

pre callback: switch on up to 8 lights with pfLightOn()
post callback: switch off these lights with pfLightOff()

This works well, but the frame rate drops. I think the
bottelneck will be the node-callback of the draw traversal. Is there
another way to attach more than 8 lights to the scene, at which the
lights only have to illuminate parts of the geometry.

Thanks in advance
