`S`

Eliminates irregularities in the area of the mesh within the brush’s influence by smoothing the positions of the vertices.

- Deformation
Deformation type that is used in the brush.

- Laplacian
Smooths the surface and the volume.

- Surface
Smooths the surface of the mesh, while preserving the volume.

- Shape Preservation
How much of the original shape is preserved when smoothing. Increasing the value reduces the effect of having multiple iterations on the strength of smoothing.

- Per-Vertex Displacement
How much the position of each individual vertex influences the final result. Increasing the value reduces the overall strength of smoothing.

- Iterations
Number of smoothing iterations per brush step.

Muista

This method works by applying regular smoothing, computing the difference between the original (blended between start of iteration and fully original based on

*Shape Preservation*) and the smoothed mesh, smoothing these offsets, pushing vertices back using the smoothed offsets, and finally blending in the original mesh based on*Per-Vertex Displacement*.
