soft modification
 
 
 

A tool that lets you push and pull geometry as a sculptor would pull and push on a soft material when sculpting. The amount of deformation is greatest at the point being pushed or pulled, and gradually falls off further away from the center.

The Soft Modification Tool is applicable for NURBS surfaces, polygonal surfaces, subdivision surfaces, curves, particles or any object with components. It works on clusters like a deformer.

The Soft Modification Tool is located in the Toolbox (or at Create Deformers > Soft Modification).
