I have an actor with a collision sphere as root component, and a skeletal mesh attached to it. Both components have gravity enabled in their details/settings.
The actor starts in the air, i.e. a few units above the ground plane.
Now when I run the game nothing happens, the actor stays “floating” on its spawning position.
However, when I enable physics for one of the two components and run the game, then the actor correctly falls down to the ground.
From the third person example I can see that the player character gravity works even without physics enabled.
Unfortunately I cannot find the difference between the example and my custom actor.
Any ideas where I could look for the cause of this issue?
