How to control 3D animation if multiple sequence are created (steps)?

Acrobat 3D version 7 and 8 only seems to read the first sequence when converting U3D files with animations from the toolkit. You can implement what you want to do by creating a single sequence with all of your steps in a single sequence. You then would trigger a specific range in the animation sequence with a method like this:

function Context()
{
return getAnnots3D(0)[0].context3D;
}


function PlayRange (start, stop)
{
Context().MyAnimation.setPlayRange(start, stop);
Context().MyAnimation.reset();
Context().MyAnimation.play();


}


You can add the routine above to the Document level javascripts defined in the AnimationController.pdf document you reference above.

Some more investigation of this problem indicates that the use of sequences will actually result in multiple animation sequences in the U3D file that Acrobat 3D embeds in PDF.

Please any one help me to create play range for above script
