This is hard to explain so I'm hoping the pictures will help.
I'm trying to make a half sphere with a cutout shape. In this case, a crescent.
I want the cutout to scale inwards smoothly and gently, looking more beveled than punched through, but still be able to make it decently deep.
It looks like garbage. I'm trying to go for a very natural, organic indentation that doesn't have a huge overhang like that.
I hope this makes sense.
