Hi Ali, I think your approach is somewhat wrong. You should'nt add interpolators at runtime, instead add them at construction time in well defined places, and at runtime you just activate or deactivate them according to your logic.
Now, if I'm looking at the TransparencyInterpolator I think that what you want to do doesn't need the parent of a Shape3D, but instead the TransparecyAttributes of it's Appearance. What I'll do in your place, is to create for each object / group of objects that should be animated, it's own Appearance object, with a stock TransparencyAttribute. I'll create one single TransparencyInterpolator which I'll add to the main BranchGroup in deactivated state. That Interpolator should be created on a specific TransparencyAttributes object. When you want to animate a Shape3D, you just replace the default TransparencyAttribute with the Interpolator's one and start the Interpolator. That way you don't need EVER access to the structure of your scene, you only change the attributes.

[Re: help needed urgetly] Dear all, I don't know whether this problem is too difficult to resolve. I sent several messages to the list but couldn't get a response to help me. What I am trying to do is adding a TranparencyInterpolator to the parent of a Shape3D object during the runtime so that I would have the animation of my current scene. Therefore I am trying to access to the parent of a Shape3D object during the run time. However, I am getting the exception: "Cannot get the parent of a live or compiled node". I can only add the TranparencyInterpolator during the run time because the user should determine the Alpha value during the run time. My questions are: 1) How can I access to the parent of a Shape3D object during the run time? 2) If I add TransparencyInterpolator to the parent of my Shape3D object (which is a TransformationGroup) during the run time, do you expect that I would get an animation of my compiled scene?
