A mesh-based cleanup is sometimes needed when the cleanup is of more complex character. The Mesh-Based Cleanup () node is added automatically by the cleanup process and always starts with an Import node that imports a surface mesh of the geometry. If there are more than one Mesh-Based Cleanup node, they will be gathered under a Mesh-Based Geometries node. The process then adds mesh operations to further clean up the geometry.

See The Mesh Node for information about these settings.
