So the collision boxes are added to the mesh if the mesh has sockets, all the furniture pieces use the same furniture parent BP and just change their function based off an Enum.
So as you can see the boxes are not added as components unless they are needed.
They are set up as a relative scale of 1, 1 ,1 and the box extent is set to 10, 10 10.
This is the display item actor which is what holds the static mesh, this is also set up to be a relative scale of 1 across the board.
is this what you needed or did i misunderstand?
