Thank you aggiechase37,
this was not so easy, Aoktar has implemented realy quick and it´s a bit buggy i think.
One of my problems was the tiny scale of the explosion and the second is, you dont can move the xp-domain out of the world-center. That is not so easy if you have a animation.
But it works.
Thanks to Aokter for quick implementing.
See my setup in the screenshot.
