moving lifting crane - collision with other 3d models does not work

Hi,

I have a problem with setting up working collisions .

I know that you can make collider on object. that works when I am walking with player and can’t go through crane elements.

But when I start moving crane itself ( I have widget with buttons, controlling crane base/pedestal rotation, crane boom rotation, and for hook going up and down.) - then crane’s boom is going through all objects without boom stopping when touching other 3d models on the way of its movement.

I am beginner in UE, my knowledge is quite limited here, but I was thinking that as soon as you will apply collider to a 3d model, when you will start controlling it it will collide with other 3d models that have collider on.

any ideas?
