There are currently four ways in Blender to procedurally duplicate objects. These options are located in the Object menu.
- This creates an instance of all children of this object on each vertex (for mesh objects only).
- This creates an instance of all children of this object on each face (for mesh objects only).
- This creates an instance of the group with the transformation of the object. Group duplicators can be animated using actions, or can get a Proxy.
- For animated objects, this creates an instance on every frame. As you will see on this topic’s subpage, this is also a very powerful technique for arranging objects and for modeling them.
