To instance an object in Blender, use linked duplication or collection instancing instead of a normal duplicate, so the copies share the same underlying data and stay lighter in the scene.

Fast method

  1. Select the object.
  2. Press Alt + D to create a linked duplicate.
  3. Move the copy where you want it.
  4. Edit the mesh in Edit Mode, and all linked duplicates update together.

Collection instancing

  1. Put the object in its own collection.
  2. Select an empty or another object.
  3. Set the object’s Instancing option to Collection in the Object properties.
  4. Choose the collection to instance.

Vertex or face instancing

Blender also supports instancing children on vertices or faces , which is useful for scattering repeated objects across a mesh.

When to use each

  • Use Alt + D for a few repeated objects that should share mesh data.
  • Use collection instances for groups of objects or larger reusable sets.
  • Use geometry nodes if you want procedural control and large-scale scattering.

Small tip

If you want one instance to become independent, make it unique by breaking the shared data link from the object data settings.
