What about setting up node or channel traversal masks ? See the manual
pages for pfNodeTravMask() and pfChanTravMask() for further details.
Alternatively, get hold of a set of the new Performer training notes -
they are excellent and give some good examples of using node and channel
masks (of course, your local SGI salesman may want to *sell* you a copy
through your attending a training course, but that's for you to
negotiate over...grin).

Are you sure about this ? Are you *really* sure about this ? Can't
rememeber the pf function at this moment, but you *can* reference nodes
by name. I did this as an experiment very recently: I used to think you
had to build models into separate files and load them with lots of calls
to pfLoadFile() if you wanted to be able to reference them uniquely.
However, an Australian knight in shining armour showed me that this
isn't necessary provided you give the sub-objects sane names (and even
then all is not lost).
Best wishes to everyone in pfLand()
Colin
PS Guesses as to the identity of the said white knight should be sent to
me on the back of used $5 bills. There may be a prize for the first
correct answer not sent by an employee of SGI...
