destrucible meshes

i create a destructible components but it always get destroyed everytime it get touch by anything even when my char walk in front of it .

i want to create meshes that get destroyed only when it get hit by projectile. or when it get hit 5 times or have to be powerfull and fast projectile how do i do that??


Add Blocking Volume around your Destructible Mesh and switch Collision Preset parameter to Projectile. Now BV blocking player and becomes transparent for Projectile.
