AR Foundation - Phyiscs and World Origin

Hi,
I have a scene which should be placed on top of an image which is tracked by AR Foundation 3.

In the scene I am placing a prefab based on image tracking. In the prefab there are multiple effects using physical movements and freely moving rigid bodies.

Because the instantiated prefab is always re positioned in the scene based on the image tracking the positions, axis and directions of the instantiated prefabs are always moving. This is preventing correct physical behavior because this also creates forces on the objects.

I would like that the scene is always re positioned based on the tracked image but the axis directions of the scene should not be moved because this influences physics. This means that the world origin should always follow the tracked image. By this the position and orientation of the instantiated prefab will not move. Does anybody knows how to do that?

Best regards
Thomas

This might give you a little more insight https://developer.scape.io/documentation/#/world-scale-ar.md

Hmmm…thanks… but I don’t see an answer to my question. So how do I constantly align world origin with a tracked image?
