Hi.

Basically I need to allow user to put objects in the ground, he can place them based on mouse position, so you could place it everywhere. I want to script something to avoid user to put objects below the ground, so for this, my idea is to create a collision box below the object, and if that collision is dettected by an object “floor”, i will allow to place it.

But the problem, is that Overlap event is never triggered when it’s overlapping the floor.
How can achieve this?

Collision Overlap setting: “OverlapAll”

Thanks!

In order to overlap, it should have “Generate overlap event” in bouth actors (Land and other actor)

That did the trick.
