Array Modifier Tool creates structured GameObject arrays through a focused editor workspace with live previews, repeatable parameters, and Unity Undo support. Choose from 29 built-in layouts, ranging from linear, circular, matrix, and spiral arrangements to procedural galaxy, DNA, lattice, hex-grid, surface, noise, and flow patterns. Every mode exposes only its relevant controls while shared transform, randomization, gradient, symmetry, preview, and execution tools remain consistent.

Generated arrays retain group metadata, so you can select an existing result, revise its parameters, apply an update, remove generated items, or reset the setup without rebuilding the workflow. A detachable preview and Scene gizmos make dense layouts easier to inspect before committing scene changes.
