AutoModular

AutoModular is an editor-only workflow tool that eliminates repetitive manual placement when building modular environments. How it saves time: Place a few modular prefab instances in your scene. Open Tools > AutoModular > Pairing Tool and hit Scan Scene. AutoModular measures bounds-center distances between your pieces and writes every valid connection into a reusable ScriptableObject database. Select any placed prefab and open Tools > AutoModular > Snap Context Window to see all its stored connections. Hover a connection to see a live ghost preview of the target prefab in the Scene view. Click to place the connected piece instantly at the exact offset recorded during the scan. Click again to remove it - fully undoable. What you get: A custom inspector for the database so you can clean, rename, or manually tweak connections without touching code. Range, text, and placement-state filters in the Snap Context Window to browse large kits quickly. Collapsible prefab group headers with persistent foldout state that remembers your layout between sessions. Undo-safe spawn and destroy for every placed connection. Zero prefab asset modifications - your original modular pieces stay untouched. No runtime overhead - everything lives in the Unity Editor. Ideal for level designers working with tile-based, wall-kit, road-segment, or any prefab-driven modular workflow.
