Hi Josh Not an expert on this but being as I have been doing a fair bit with picking lately I thought I mioght have a crack at helping you. It is not possioble to get the parent of an object at runtime but I find two things are needed to solve you problem. firstly if the scenegraph path objcet will only return objects that have the correct capability set (pick reporting I think!). Secondly carefully design the ".userData(Object obj)" then user setUserData(obj); and new oBj = getUserData()
Then I use a string that I frmat and tokenise on reading it to get all the required data I need. e.g Parents name, Translational vectors (needs casting back into double or floats after reading from the stringTokeniser()) and even if their are children attached. Hope this helps.

Now I'd like to be able to distinguish which avatar was picked.. not just the Shape3D. I had the "bright" idea to extend BranchGroup with a class that includes a reference to the avatar object thinking that I could chase this parent up from the leaf that is picked. Of course when I tried this I get the restricted access exception. > >Is there an easy way to do this? > >I looked at the result returned by getSceneGraphPath but it always claims to have 0 nodes!
