Skeletal mesh socket problem

Hello.

Why, if i attach some static mesh into socket of some skeletal mesh, it is not for example rotating with the skeletal mesh?

I found, that if i uncheck Simulate physics, then it will rotate with skeletal mesh, BUT… if i spawn this child object runtime, then runtime i set Simulate physics NO, and then i attach in socket, it doesnt rotate with skeletal mesh again :((.

(BP functions - SpawnActor XY → Attach Actor to Actor (in socket name…) → Set simulate physics… (or i tried first set sim physics then attach, but no difference, unless i disable physics in the BP Components tab of the object i want to attach to socket)

What to do, or why?

Thanks,

L.

I see now, that problem is, that simualte physics cannot be changed runtime. Or in another words, it has no effect?
