At some point, you will come to a time when you need to cut parts away from a mesh to be separate.
To separate an object, the vertices (or faces) must be selected and then separated, though there are several different ways to do this.
Separates the selected elements.
- By Material
Separates fragments based on the materials assigned to the different faces.
- By Loose Parts
Creates one object for every independent (disconnected) fragment of the original mesh.
