About

The Smooth tool averages the differences between vertex positions along a axis (set by Direction). Use this mode to make your jagged vertices more uniform.

Usage

Select any mesh object, enter Smoothing mode, then click and drag while hovering over the selected mesh.

See the Brush Settings page for information on modifying brush radius, falloff, etc

Smoothing Mode Settings

Ignore Open Edges

Setting	Description
off	All vertices will be affected
ON	Vertices on the edge of the mesh will be ignored

Brush Normal is Sticky

Setting	Description
off	Vertex movement direction will be picked every frame, from the surface below the mouse
ON	Vertex movement direction will be chosen on click, and stick to that direction

Direction

Setting	Description
Up	Move vertices on the Y axis
Right	Move vertices on the X axis
Forward	Move vertices on the Z axis
Brush Normal	Move vertices in the Brush's "up" direction
Vertex Normal	Move each vertice along their own normals

Tip: Use Vertex Normal on objects like spheres where you want the movement to be relative to the direction of the affected vertices.

Tip: In Smooth mode the Vertex Normal brush direction behaves slightly differently than you might expect - instead of constraining the movement path to the normal each vertex position will be averaged with it's neighbors. This is very handy for reducing large gaps in vertex positions and making your mesh look super-smooth.
