Sorry for the noob question:
I'm stuck on creating thickness to a sphere to feed it to a flip simulation or a vellum fluid sim.
I would like water to be emitted only from the thickness of the sphere not from the inside part. I've tried polyextrude and labs thicken sops but points from volume scatter points all over the inside of the sphere, not only on the extruded geometry.
Could someone please tell me the correct workflow to give thickness to a sphere.

thanx
