How to setup local multiplayer with First Person startup content

Hi,

I am using the First Person startup Content and i want to setup a local game. I have no problem testing it with two players with one on the keyboard and the other on the gamepad. And, i am using destructible mesh in my gameplay.

First problem : The first player cant see the projectile shot by the second player and vice versa

Second problem : when a player shoots on destructible mesh, the other player cannot see the destruction on his side
