i have this blue print :
static mesh settings:
and this sphere collision settings:
and i don’t know why when i fire that sphere , she get through everything , even if i set collsision presets on BLOCK ALL on static mesh and on sphere collsison. Any idea why is this happening? 
Thanks a lot , i’m stuck!
i think your sphere collision settings are set to overlap all dynamic as shown in pic @pax0ff ,
set that to block all and try again ,tell me is that works or not, there can be many reasons.
why are you adding collisions manually , do they serve an special purpose? because it can collide even without that.
is not working 
, same thing , is getting through all objects on the map , and i don’t know why.Tell me if u need more pictures with other details.HAND
Open the static mesh and make sure there is a collision object?
how are you moving the object and what all is it getting through? what all is there in your BP except collision and meshes? try enabling simulate physics to see if that works
