So after messing around a bit it seems the root of my issue is caused by inherited classes or something.
The problem seems to be that the 1st child is a Static Mesh Component that is not editeble. “you cant change its child posision”
So using example the function Add Impulse will have no effect on the Mesh. it will affect the Primitive Components.
If i could swap the MyStaticMesh Component with example APMineOnOf or any other Component i could use Add Impule.
Any ideas to how i can make MyStaticMesh editeble so i can change its child position in the hierarchy ??
