Blender 2.8 Boolean inconsistencies I'm trying a simple boolean add. I select the first object (sphere) then add a boolean modifier (cube).
In first attempt with sphere in position 1, the results are as expected.


When I move the sphere to the left, and apply the modifier, the sphere disappears.


Any help greatly appreciated.
I had an object of the same name that was hidden in a different collection. When I renamed the cube the modifier worked correctly. Blender doesn't like duplicate names for objects. Hope this helps someone.
