Hm. osg::Sequence nodes support OpenFlight Group record animations, and
OpenFlight supports a "backwards" flag. However, upon closer inspection of
the OpenFlight loader, I see that the backwards flag is essentially
ignored...
Sorry, no help here. Maybe others will weigh in.

Hi,
I'm looking for a geode collision detection. I don't see one in OSG. Or

The current sequence node only supports time going forward, or stopped,

could run the sequence nodes back and fort
