Hi Tina,
Looking at your code , I think you get the exception from the removeScope
call. When you initially do addScope you do it with object "objBg". Are you
sure you initialiaze that object before your call to createModelClip?

Hi,
How do you detach the branchgroup. If you are using an index do you start
> from 0, or do you use the right one?
> Don't you have a variable for your branchgroup? You can then use

this is what I am doing :
BranchGroup bg;
createModelClip(BranchGroup objBg)
{
bg = new BranchGroup();
bg.setCapability(BranchGroup.ALLOW_DETACH);
ModelClip mc = new ModelClip();
----
mc.addScope(objBg);
}
removeModelClip()
{
if(bg != null)
{
mc.removeScope(0);
bg.detach();
}
}
Thanks
Tina
