Default Shortcut: None

Menu Path: Modify > Smooth


The Smooth command will in essence average the positions of the selected vertices, evening out irregularities and extremes and generally smoothing the surface. The command works in any selection mode, but always works on the vertices of the selection.



Determines how many times the algorithm will be run when you use the Smooth command, and thus the amount of smoothing which will occur.

Volume Preservation

A factor intended to counter the natural side effect of shrinking the model which Smooth can have. The closer this value is to 1, the more the algorithm will attempt to expand the vertices while performing the Smooth operation.

Also Known As

This function is also known in other applications as Average Vertices, Tighten, or Relax.


  • There is also a Smooth brush when using displacement painting (see Paint Displacement), which you may prefer to use depending on the situation.
