[JAVA3D] Adding nodes

[Alex]

Hi All,   I have a problem trying to add nodes which already has parents to another branchgroup. My error is :   javax.media.j3d.MultipleParentException: Group.addChild: child already has a parent   I need to group certain nodes that I get from the parent so that I can perform some calculations on them. Any help is appreciated.   Thanks in advance.   - Alex -
