Pinch
What is it about?
This page documents the Pinch brush for sculpting in Cinema 4D. It draws vertices toward the stroke center, sharpening soft transitions — the standard brush for accentuating edges, ridges and crisp creases.
The Pinch brush pulls the mesh vertices beneath the brush together in a direction perpendicular to direction of the stroke and towards the center. This is a good way of accenting edges or creating edges or ridges.
