Makes copies of all particles to visualize multiple images of a periodic system.
Enables the generation of copies of the system in the three spatial directions. You can control how many times the system is duplicated in each direction.
If this option is active, the simulation cell is also extended to match the size of the multiplied system.
When duplicating each particle, the modifier also copies all assigned properties including the particle's identifier. Thus, applying this modifier will lead to duplicate identifiers. Keep in mind that this may cause problems with other modifiers (e.g. the Manual selection modifier) that rely on the uniqueness of particle identifiers, and which following in the modification pipeline.
