Collision and Dynamically Generated Child Meshes

Hi. I am trying to recreate a destructible mesh effect for android, and I have a parent mesh which loads smaller child meshes on contact. The problem I face is that when this happens all the child meshes lose collision. In blueprints I have experimented with setting various collision settings and enabling collision after the child mesh is created but nothing seems to work. I wonder if anyone has any insight into how I might be able to make sure the child meshes have collision?

After some more research on similar issues, it’s beginning to seem like this is a feature rather than a bug.
