I'm working on a volume shader.
To avoid of overdoing it's effect, I would like to "tag" the ray so I could determine if the ray already traveled through another volume using the same shader (maybe even a different instance).
Any ideas anybody?

I don't think that's possible. (For obvious reasons the ray structures are as light-weight as possible. There's no room to attach your own data.)

mmmh, maybe the other way round? Is there some ray ID or something similar?
