Hi again,

I have the following tree:

|
     pfLOD
     / \
 pfDCS1 pfDCS2
| |
pfGeode pfGeode

Upon a LOD change, I want to set the matrix of pfDCS2 to that of pfDCS1. How
can I manage to do this in a multiprocessing application, knowing that my
performer tree is created after pfConfig()?

If I set a pre-cull callback function on pfLOD to do the job, it does not work
because a copy of pfLOD is passed. Thus, it is set in the cull process but it
is not actually updated in the app. process (as I checked by reading the matrix
one frame later).
I know I could place one pfDCS above pfLOD but in fact, the above drawing is a
simplified version of my actual hierarchy:-)

Thanks in advance,

Amaury
