Trigger/Collision fires late

Development Getting Started & Setup

I try again to get help, with a basic question (I think)
I have a conveyor belt that moves the object forward thanks to a Collision overlap event.
On top of it I want to count how many objects are present in a certain volume.
To do so, I’ve tried to place a second Collision box or a Trigger-Box and monitor ActorBeginOverlap/ActorEndOverlap

Collision_1
Collision_12594×781 82.4 KB

But the events get fired only when the objects leaves the Collision area overlap of the conveyor belt.
So is not not possible to register two Collision/trigger events at the same time or what?
How would you do it?

I don’t understand. Can you rephrase the problem? I read your other thing and if you are generating images, why do you need a conveyor belt?

If you want to count object in a volume, you can use GetOverlappingActors which might be easier.
