Is there a way to make translucent trigger box?

Is there a way to make translucent trigger box?
For example, there is a translucent trigger area in Serious Engine. I think it’s more intuitive than wireframe.

Also it takes to make mesh invisible in a game:)

You can use a mesh with translucent material, set it’s collision preset to OverlapAll and then use its overlap events.

You can enable Actor Hidden in Game in the mesh’s details panel.
