Can anyone help me?
I tryed this code and the VM throws a MultipleParentExeption


ObjectFile file = new ObjectFile();

Hashtable objects;
try {
objects = file.load(url).getNamedObjects();              
catch (FileNotFoundException e) {
catch (ParsingErrorException e) {
catch (IncorrectFormatException e) {

Enumeration e = objects.keys();

while(e.hasMoreElements()) {

 String name = (String)e.nextElement();
 Shape3D part = (Shape3D)objects.get(name);

 if (name.equals("gun")) {
      System.out.println("set gun");
      this.gun = new TransformGroup();
 }else if (name.equals("body")) {
      System.out.println("set body");
      this.robotbody = new TransformGroup();
 }else if...


set gun Group.addChild: child already has a parent
     at engine.object.Robot.init(
     at engine.object.Robot.<init>(
     at engine.object.ObjectManager.addRobot(
     at engine.Metaversum.createSceneGraph(
     at engine.Metaversum.init(
     at engine.Metaversum.<init>(
     at engine.Driver.main(
Exception in thread "main"

Is it not possible to split a obj file in different Transformgroups?
If yes, please let me know.

When loading a model, all nodes already are organized in a scenegraph and therefor have a parent.
So you have to detach it first before you can add it to you transformgroup.

Thank you for the answer.

But how should I detach the childs?
getNamedObjects() returns Shape3D

That's how it's meant to be.
The question remains why you load a model with submodels where you are only interested in the submodels. You are creating some overhead....
