How to Disable collision when a destructible mesh is destroyed?

Hi I am New to Unreal and I am having problems with Collisions , so I learned how to make destructible mesh but I realized that the destructible mesh has no collision, I don’t know if I am doing something wrong. So I decided to just make a copy of that tower and give opacity so I can walk on it. I want to know how can I disable that tower that has the opacity and collision on it when the destructible mesh tower is destroyed. Thank you

The easy way to make the Blueprints and use a “Is Valid” node, so if the Tower Blueprint is not valid, the destroy the opacity.
