This option allows posing meshes with different disconnected elements
using the Pose Brush.
This is achieved by doing the following:
- Creating an ID per vertex that stores the loose part of that vertex.
- By using those IDs, one fake topology connection is created per vertex to the nearest vertex in a different ID. The maximum distance to create that connection is determined by the "Max Element Distance" property. These fake connectivity neighbors are used in the Sculpt API functions iterators, so all the algorithms of the Pose Brush can run without modifications as if everything was part of the same mesh.
