I created a class blueprint called PhysicsBox, which contatined a static mesh with enabled physics. Then I created an empty class blueprint which was called ManyBoxes (from QuickShot tutorial No. 6) which created PhysicsBoxes as child components.
The blueprint that I used in ManyBoxes:
Radius and HowMany are editable variables.
But when I tried to use it, I found that all child components are moving away. I tried to use wallSconce blueprint with enabled physics, and all worked perfectly.
I checked the differences between this two blueprints, and found that PhysicsBox doesn’t contain Scene component, but the wall sconce contatins. When I added it to PhysicsBox, all worked right.
I created a thread about this on forum, where this problem is described with more details and photos (answerhub has a limit of photos): Child component moved away - Blueprint - Epic Developer Community Forums
With best regards,
