Is there a way to force the Physics to run for a period of time before the scene starts, I have a bunch of spawned rigidbodies which I would like to have settled down in the scene before the game starts.Is the a simple way to do that, or do I just need to site and wait with the camera turned off so no rendering is done but everything else runs as fast as possible.
you can temporarily set the timescale for fixedupdate larger so it does more work, but you will have to have some period of black screen, yes. Until unity adds simulating it. You’d have to ask them, since it doesn’t exist presently.
