    Hi,

    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?

    Thanks!

    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?

    Thanks anyway!
