Hi,

I have another question for the group.

Overview:

I have two pfChans in the same window. Each pfChan (not a channel group) has a different view into the same pfScene. Many of the pfNodes in the pfScene have draw callbacks that render a text label identifying the pfNode.

Now to my question.

I need the text identifying each pfNode to be different depending on which pfChan the scene is viewed from. I know how to pass use pass through data but don't know how to tell a pfNode which pfChan it is viewed from. How can I do this?

For example:

      pfNode #1 in pfChan #1 should have a label "ABC"

and

    pfNode #1 in pfChan #2 should have a label "XYZ"

Thanks in advance for your help
