What version of Performer are you using? I found that in v1.0 and v1.1
that the pfFindNode does not work so I wrote my own. Basically, I had
pointers to the DCSs in the original. After I cloned, I backward
traversed (pfGetParent) the original scene graph until I reached the top level
node that was cloned (storing the path on a stack as I went up). I then
traversed downward using the names of the node stored on the stack one
level at a time.

If there is an easier way, I would like to know about it.

Hopefully, pfFindNode works in 1.2.
