Remove unused vertices from a subdivision surface
 
 
 

You can use Clean Topology to remove any vertices that were created but not used in a subdivision surface. Removing the extra, unused vertices helps to reduce the file size and improve interactive performance.

For example, if have refined some regions of a subdivision surface, but moved only a few of the vertices created by the refinement, Clean Topology can remove the vertices you did not transform.

To automatically reduce unused vertices in a subdivision surface

  1. Select the surface whose unused vertices you wish to remove.
  2. Select Subdiv Surfaces > Clean Topology.

    Any unused vertices are removed from the subdivision mesh.

Notes

Clean Topology only removes a vertice if it meets all three of the following requirements:

There may be some vertices that Clean Topology cannot remove, even if they meet these requirements, because the vertices are required for surface topology.
