Instantiated object to ignore an empty object with box collider

I have played around with the Physics.IgnoreCollision script for a quite a while now and got it to ignore the launcher, but I also want the the instantiated object to ignore the empty box collider that the player sits on (called invisible1 in project view). I tried adding the Physics.IgnoreCollision after the line that ignores collision with the player controller but it does not recognize the invisible1 object. Thanks in advance for any advice or what simple thing I am not seeing!

Sorry all,

Fixed issue. Assigned Missiles to created 'Missiles' Layer and all invisible box colliders to 'Invisible' Layer and then unchecked the corresponding box in the Edit>Project Settings>Physics. Easy-Peazy, Lemon-Squeezy!
