[SOLVED] How to trigger a trigger box only with specific actor?

Hello I have a problem. I want a trigger box that moves over time and eventually hits my players but it hits other actors first and is triggered from that. Is there a way to make it so that the trigger box will only trigger when a specific actor (or character or something) overlaps with the trigger box?

Use cast to actor or actor has tag or custom collision channels.

Okay somehow I accidentally did the opposite thing and made the actor that I want to be able to trigger the trigger box no longer trigger the trigger box and the actor that I don’t want to trigger the trigger box continue to trigger the trigger box. I didn’t use EvilCleric’s method when I did this. Does anybody know how this might have happened?

Thank you this worked!
