Surface Deviation

The deviation factor used when comparing mesh surfaces to determine if the objects are similar.

Mesh Area Deviation

Search In Children

Whether or not an extra filter should be applied to the objects using mesh area comparison.

  • Mesh Area Parent: The parent object under which the mesh area comparison must be done.

Check Circumference

If selected, use the circumference of a plane on the mesh (an area where connected triangles have a similar normal) as a comparison to check if objects share this plane, as an extra similarity check.

Keep Local Rotation

If selected, ensures that the local rotations of the prefab instances are the same as the object that they replace.
