[osg-users] Force osgDB::readNodeFile to not return cached model

[Voerman, L.]

Hi Brad,
I think your code should work, but instead of disabling the cache you can
clone only the parts you need:
osg::ref_ptr<osg::Node> newNode = dynamic_cast<osg::Node
*>(oldNode->clone(osg::CopyOp::DEEP_COPY_NODES));
Assuming the rotating is done on a Transform node, this will let you share
all geometry and statesets.
Laurens.
