Tool

Toolbar ‣ Boundary

This tool is used to transform and deform the boundaries i.e. the unconnected edges of a mesh. The tool detects the mesh boundary closest to the active vertex and propagates the deformation using the brush into the mesh.

Note

Even if this brush can produce deformations in triangle meshes and meshes with a non-regular quad grid, the more regular and clean the topology is, the better the result.

Deformation Target

How the deformation of the brush will affect the object.

• Geometry

  Brush deformation displaces the vertices of the mesh.

  Cloth Simulation

Deformation

Deformation type that is used by the brush.

Boundary Falloff

How the brush Falloff is applied across the boundary.

Boundary Origin Offset

Offset of the boundary origin in relation to the brush radius.

• Constant

  Applies the same deformation in the entire boundary.

  Brush Radius

  Applies the deformation in a localized area limited by the brush radius.

  Loop

  Applies the brush falloff in a loop pattern.

  Loop and Invert

Usage

The main use cases of this brush are the Bend and Expand deformation modes, which depend on a grid topology to create the best results. In order to do further adjustments and tweaks to the result of these deformations, use the Inflate, Grab, Twist, and Smooth deformation modes, which do not depend that much on the topology.
