topology-independent Smooth deformer

[wesserbro]

As many of you know, 3-edges (as well as 5,6..) vertex are bad for sds and smoothing.
I'm looking for a smoothing deformer that does not produce those nasty pinches on any quad topology (im gona use it after other deformers on animatable mesh). Maybe even in other package...
Any suggestions? )

1. Original low-poly
2. Subdivision surface
3. Smooth deformer
4. Topology

try to apply locally a relax deformer along with smooth
BTw there is 2 methods for SD , catmulk and another, try both

Not sure if this helps
