Generating landscape overlap/hit event?

Is it even possible to generate overlap/hit events on landscapes ? for example im creating a bomb system using projectiles where the player throws the projectile bomb which explodes on impact. I tried checking/unchecking all possible options on collisions for the projectile but nothing seem to work . Been bumping my head for hours on trying to get this simple feature to work :frowning: . Does anyone have a solution for this ?

Thanks
