No collision propagation on child components.

Hi!

I have a problem with an actor that has a hierarchy of static mesh components (A is attached to Root, B is attached to A, C is attached to B - I want it to work like an arm). What I’m trying to do is to rotate one of those components, but the rest of them doesn’t have collision with anything - the collision detection doesn’t propagate.

Actor must be working with physics simulation enabled. Does anyone know what the solution for my problem?
