Hello:

We're creating a fairly deep node heirarchy in Performer (at least 70
pfDCS and pfSCSs deep), and get a matrix stack overflow when Performer
traverses for the cull (this is a modified perfly program).

Performer Warning (9):pfPushMStack: Matrix stack full

it then core dumps.

It seems to be pushing the matrix stack at pfDCS node (and pfGroup
nodes), but is not really necessary at each level for our application
(there are only about 5 max branches in our articulation tree going
down any one path in the database). so I was wondering how I can
control Performer's pushing and poping of the matrix stack using the
node callbacks (to suppress the unnecessary pushes). Does anyone have
an example of this?

Thanks
