Hi Dominik,
it looks like you have a problem with reference counting:

osg::NodePath& fullNodePath = nv->getNodePath();
osg::ref_ptrx = fullNodePath.back();

fullNodePath.push_back( x.get() );
}
assigns an 'osg::Node*' (from 'getNodePath') to a smart pointer.

It turns out that I was able to compile and link 2.4 and 2.5 , but

Hi Mike,
I have a simple repro of this problem. See the attached .osg file.
It's a super simple shader that colors an object blue or red depending
on a bool uniform. The default state on the parent group sets this
uniform to 0, then one of the children overrides it with 1. You'd
expect to see

I haven't heard of NodeTrackManipulator sef faulting before, so this

if that runs stable.

Hi John,
VPB builds purely static databases that are stored on disk to be later
loaded by the runtime that visualizes it. Since you want to vary the
vertical exaggeration at runtime then the solution will have to be
entirely on the OSG side, VPB actually has little to do with the

Hi,
When creating globes with VPB one can use the option -v (vertical

exaggeration).

Hi Valery,
Geode's are meant to be leaf nodes, so are no intended to have
children other than drawables - which is why traverse() isn't
appropriate in this case.
If you do want to customize behaviour then could implement override
the Geode::accept() method, this is called before the
NodeVisitor::
Thanks a lot for explanation to you and Артём, but my class is derived
from Geode, therefore osgUtil::UpdateVisitor::apply(Geode&) calls
handle_geode_callbacks(osg::Geode& geode), which doesn't call traverse
anyway:
// should we traverse just in case a subclass of Geode adds children??
Won't for no
