Adding Object on Collision

I am very new to UE and Blueprints so I’m looking for a little direction on how to do this.

I want to add an object when one object collides with another. More specifically, I have a shovel and I want to add a texture that looks like a hole (no actual terrain modification, just the texture) in that area. I’m thinking the easiest way would be to add an object with the texture on it when the shovel collides with the floor/ground. I am just really lost on how to go about doing that. Thanks!
