Similar to the Pose brush but deforms the open boundaries of a mesh. The tool detects the mesh boundary closest to the active vertex and propagates the deformation using the brush Falloff into the mesh.
The main use cases of this brush are the Bend and Expand geometry, which leads to the best results on evenly distributed quad based topology. Use the Inflate, Grab, Twist, and Smooth deformation modes, to further adjustments and tweaks to the result (which do not depend that much on a clean topology).
Boundaries to hidden geometry will also be counted as an open boundary.
The boundary origin is displayed via a white line, which indicates the reach of the deformation. The targeted boundary that will be deformed is highlighted in the brush cursor color.
If the Deformation Target is changed, the brush can also be used for cloth sculpting.
Evenly distributed and quad based topology will lead to much better results. Triangles and N-gons are also supported but may lead to unpredictable outcomes.
Rotates the boundary around the local Y axis. Useful for creating folding shapes, like sleeves.
Moves/extends the mesh boundary in the local X direction. Useful for extending the boundaries along the surface.
工作原理类似于 膨胀 工具，但充气的顶点被限制在网格边界内。
工作原理类似于 抓取 工具，但是，抓取的顶点被限制在网格边界。
Rotates the active boundary around the local Z axis. Useful for creating folds like on a skirt.
Works similar to the Grab tool but, the vertices that are smoothed are constrained to the mesh boundary.
Applies the deformation only within the brush radius.
Applies the brush falloff in a loop pattern along the boundary.
Applies the falloff radius in a loop pattern, inverting the direction back & forth.
