3Ds Max - Squeez
Squeeze
The squeeze modifier let you apply a squeezing effect to the objects, in which the vertices closest to the objects pivot point move inward. The squeeze is applied around the squeeze gizmo’s local Z-axis. You can also use squeeze to create a bulge on the vertical axis, to accentuate the squeeze effect.
