Ok, so for high speed projectiles, use collision as root. For everything else use scene component as root. Why scene component?
Is there any official documentation on this?
Which component do you enable “Simulate Physics” on? I assume the “interactive collision”?
Root components cannot be moved/rotated in the actor itself. It’s stuck at 0,0,0. Child components can be manipulated. It’s what allows us to rotate the prop so it lays flat.
Physics applies to the mesh. The interactive collision is a child of the mesh so it will move with it.
Once physics goes back to sleep you then have to shift the Actor (self) to the meshes new location. As noted in the video above.
