OH RIGHT. Good point, a kind of "chicken-and-egg" problem. :) Try this, and I'll try it to as soon as I can: create a CullCallback that calls isCullingActive(); if so, set NodeMask to something wonky. Attach the CullCallback to your Geode. (This is just from a cursory look at the API and from experience, I'll try it soon...) > So I am wondering if there is something I don't know since it seems to be > very common thing to do and should be simple to do. > > Cheers, > Janna > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=49946#49946 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
