I am currently watching this tutorial…

Any solutions?

Is it character bp?
You must set simulate physics checkbox to true in settings in capsule…
But i dont recommend adding impulse… imo much better is to use “launch character” and you dont need to simulate physics… i have bad experience with simulating character physics
