Collision box makes elevator controls not work

So, i have this elevator on my project, that works just fine. Now i’ve started to set some level streaming with collision boxes. And my idea is: When i collide with the collision of the second floor, the level streaming of the first floor will be unloaded. But, the only way to make the second floor be loaded naturally, It’s by placing the collision box passing through the elevator, but when the elevator collides with the collision box, i can’t interact with it anymore, I’ve tried in every way, changing the collision preset of the box, the elevator itself, but i need the box to have collision for it to be triggered, just like the elevator needs collision so the player doesn’t pass through the floor. Any thoughts?

Your collision object to load the second floor should only respond to Pawn/Character, not any other type of object (eg. the elevator is not a a Pawn/Character).

I think selecting the Collision Preset ‘Pawn’ will fix your problem. I hope I have understood your problem correctly and that this helps.
