This script unwelds faces from one or several selected vertex/vertices.
|
|
|
|
Usage:
|
|
|
|
In edit mode Select at least one vertex, then run this script.
|
|
|
|
The options are:
|
|
|
|
- unbind points;<br>
|
|
a new point is added to each face connected to the selected one.
|
|
|
|
- with noise;<br>
|
|
the new points location is varied with noise
|
|
|
|
- middle face;<br>
|
|
the new point is located at the center of face to which it is connected
