about set visibility

I have set the fire effect to trigger upon contact and disappear upon departure, but I don’t know why it wasn’t implemented.

Hey, as I understand, you are checking component overlaps on the sphere itself. If you do not have “Generate Overlap Events” on the sphere mesh, this will not execute.

I see that you have a box collision as well, try doing the overlap event thru the box collider and see if that works.

Thanks! But I have set up overlapping events, there is still no response.
