Physics interactions between only specific actors

Hi everyone,

So I have an actor, called sphere1. I also have many other actors in my scene, including an actor that is just a platform/ blueprint that moves back and forth.

I want this specific blueprint (among a few others I will put into an array) to be able to push/ move it.

But, for every other actor not in the array I want it to overlap. (Have the collision preset of overlap all)

In the editor, Edit → Project settings → Engine → Collision → you can define your own collision object or trace channels and then set your actors up to use those specific channels for the result you want in their collision settings.

Hope that helps!
