Hi

I have a debug function called from the DRAW process (it does some GL). This
function queries the Performer scene. It traverses the scene and extracts
information about tree hierarchy and node data.
Unfortunately - when I set the pfNotifyLevel to be PFNFY_DEBUG, I get a message
for each node being accessed (for read only), which states -

Cannot access this object from this process ... (and so on)

Why is that ? The fact is I _do_ get the information, but I have to listen to
those Performer complaints.
I understand that there is no point of modifying libpf objects in the draw
process, since they are a duplicate of those in the APP process, but why does
Performer complain when I just try to read data (using the pfGet... functions)
?

Thanks

Ran
