[edit] Smooth Modifier

[edit] Description

This modifier smooths a mesh by flattening the angles between adjacent faces in it, just like the Smooth button in the Editing Context → Mesh Tools panel. So it smooths without subdividing the mesh -- the number of vertices stays the same.

This modifier is not limited to smoothing, though. Its control factor can be configured outside the [0.0, 1.0] range (including negative values), which can result in interesting deformations, depending on the affected mesh.

[edit] Options

Smooth modifier

X Y Z

Toggle buttons to enable / disable the modifier in the X, Y, Z axes directions.

Factor

The factor to control smoothing amount: The smoothing range is [0.0, 1.0]: 0.0: disable, 0.5: same as the Smooth button, 1.0: max. Alternatively, values outside this range (above 1.0 or below 0.0) distort the mesh.

Repeat

The number of smoothing iterations, equivalent to pressing the Smooth button (link) multiple times.

VGroup

A vertex group name, to restrict the effect to the vertices in it only. This allows for selective, realtime smoothing, by painting vertex weights.

[edit] Examples

Smooth modifier examples. Option "repeat" is set as 5 for all models, but each one has a different "factor" value. From left to right: Top (smoothing): 1) normal Suzanne (same as factor: 0.0); 2) Factor: 0.5; 3) 1.0; 4) 2.0. Bottom (distortion): 1) Factor: -0.3; 2) -0.6; 3) -1.0. The three models at the bottom row were subdivided twice to look nicer.
