Sphere Thickness Jan. 7, 2022, 3:37 p.m.

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

I probably need to simplify my needs and compensate with directing the shot in a certain way.
Thanx for help and also for cgwiki. That's a goldmine for people like me learning H

Thank you Mestela. That covers one part. Imagine to have a wrinkled surface where some magical spheres fall from gravity and begins to roll over the surface making it smooth. I would need to deform, displacing or "undisplacing" on normal, the big sphere in proximity of the little spheres. The little spheres should remain above the displaced surface, so they should have a kind of feedback from the newly deformed surface

here is a wrong visualization of what i need, done in cinema4d.

you can see that the "undisplacement" is been reduced by a circular shape growing. I would like that the growth of the "undisplace" started from the position of the little sphere when they touch the big one. The effect should cumulate over time so that.

I'm tryng to achieve it in sop but definetly would like that to be dynamic.
I'm pretty sure to have achieved this effect in cinema 4d on previous version but on last one the procedure is really buggy. So i said let's give it a try in houdini. I'm not that good though on H.

Thanx for your help. I really apreciate that.
