onComponentBeginOverlap not working with SM_Rock?

I was tried to do similar like in this video - YouTube (Blueprint QuickShot 2 Blueprint Pickup)
Its works well with sm_statue, sm_matpreviewmesh, but onComponentBeginOverlap event never happend with SM_Rock, I checked it with breakpoints. Why?

p.s. sry for my English

Ohh, I see, ty!

SM_Rock doesn’t have any collision by default. Just open the mesh editor and add a collision.
