Hi, Koduri Simaple animations (such as translate\rotate\scale) are usually exported as osg::AnimationPathCallbacks with osg::AnimationPath containing control points with transforms and timings. You can search graph for these callbacks and manipulate them, as they have interface functions to set pause\unpause, use different looping modes, animation speed etc.
