Robert, a dangling pointer is a probable cause of my problems. Thanks for the hint, I'll look into it. I thought it could be related to me rewriting the node's InitialBound. Thanks, Bruno 2017-06-26 10:15 GMT+01:00 Robert Osfield : > Hi Bruno, > > On 23 June 2017 at 23:45, Bruno Oliveira > wr

HI Bruno, There is no "child added callback" mechanism in osg::Group, but you can override the addChild and insertChild methods to catch attempts to add children, deferring the implementation to the underlying addChild/insertChild method and then doing what extra's you want, Robert. On 23 June 2

[osg-users] Perform actions when a child node is added
