I want to arrange a large number of item pickups in a physics-enabled pile in the editor. Is there a way to activate physics for the editor so these items will fall naturally to the ground as I place them? Or do I have to arrange them manually, or just copy and paste them all in the same location and then hide them from the player at the start of the game until the physics has dropped them all to the floor?
Simulate → select the pickups after they fall → right click → “Keep Simulation Changes”. Playing and Simulating | Unreal Engine Documentation
Alternatively, you can make a construction script or run-in-editor function that places them randomly as if they fell.
