Destructable Mesh, chunk without collision

This totally works, however,

tl;dr: Are different collision settings possible for before and after destruction ?

I am trying to change the collision behavior after destruction, i.e.

  1. Destructible Actor “blocks” pawn normally
  2. I Trigger it’s destruction and change the collision to “ignore” the pawn

However, this does not work. The chunks still block the pawn. I tried various ways, changing the collision before and after destruction. Is there any better way to change the collision of the chunks to ignore pawn after destruction.

Engine Version : 4.61

Thanks.
