Why Can't get Overlap event with the ground?

Hi guys.

I’m trying to do a simple game example where the player can place things in the ground, what I want to do, is to change my mesh into green if possition is OK to be placed, and set it in Red if possition is invalid.

For this example, invalid = Below or overlapping my ground.

Here is in the air, so I set the color in green, looks good.


But here i’m overlaping the box with the ground, and I tried all configurations possible and still I can’t get to raise Overlaps events, but just for the ground, it works fine when colliding with actors.


Can somebody guide me how to achieve this properly?
Maybe I need to do another approach?

Thanks in advice

Make sure both meshes are set to Generate Overlap Events.
