I want to use two intersecting booleans on a sphere (to make holes on north, south, west, east sides) by using either cylinders or elongated spheres. I do this by positioning my cylinder going through the object and applying the first boolean (works fine), then rotating the cylinder 90 degrees to create another boolean cut, but this either leads to the sphere disappearing, or glitches inside the object (e.g. being able to see the inner outer layer of the sphere from certain angles). Is there a fix for this? Thanks.
