But they work. That's the important part. Now, if I am using standard materials, I can use these lights with the speed of the P4 renderer, but if I am using special materials, I can still use them in Firefly. There is an option to turn on raytracing for each object, so ifI don't need the lights raytraced, then I don't need to do anything to them, but I'll still get my other scene components raytraced if I want? Or do I have to have the raytracer turned off in Firefly completely? I'm not quite sure how raytracing works. I just really like the effect it has on certain things, like skin, and fine detailed objects.
