Shake objects?

Hi

I’m following a toturial by Jama Jurabaev where he shakes the “ground” and the objects on it reacts to it.

I can animate the objects so the land on the ground, but as soon I grab the ground, the ground looses the effect on the objects.

I’m sure I just need to add a check mark somewhere in the Blender jungle - but where? :slight_smile:

Can anyone guide me?
