Hi Alexandre,
The problem is that from somewhere in the osg there is a node visitor running
over the osgPPU pipeline which hasn't specified type. I would expect here to
run the update visitor first, but there is some other visitor running, and I do
not know which one ;(, because the visitor has no specified type information
(getVisitorType() returns just NODE_VISITOR).
I have updated the trunk version of osgPPU. It seems the problems with the
cycles are gone now. Test it out. If you would like to stay on version 0.3 of
osgPPU, then you have to rewrite the ::traverse method of Processor.cpp from
the trunk in your copy of osgPPU.
Cheers,
art
