add objects to live or compiled scenegraph
..seems it's impossible add objects/transformGroups to live or compiled scenegraph, exception throws "RestrictedAccessException: Group: only a BranchGroup node may be added".
is it true, i.e. is this action restricted?
I tried workaround like this, it's working (only with live, not with compiled scene):
//objRoot.compile(); //not working with compiled scene
simpleU.addBranchGraph(objRoot); //making live
