Build modular environments faster. Auto-scan prefab connections, preview placements live in Scene view, and toggle pieces with full undo — no manual offset math needed.AutoModular is an editor-only workflow tool that eliminates repetitive manual placement when building modular environments.How it saves time:1. Place a few modular prefab instances in your scene.2. 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.3. Select any placed prefab and open Tools > AutoModular > Snap Context Window to see all its stored connections.4. Hover a connection to see a live ghost preview of the target prefab in the Scene view.5. Click to place the connected piece instantly at the exact offset recorded during the scan.6. 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.For Supporthttps://discord.gg/brU452ZNKey Features:- Scan-based pairing: Automatically detects compatible prefab connections by measuring renderer bounds-center distances within a configurable radius.- SnapDatabase ScriptableObject: Stores connections as reusable, editable data assets. Create multiple databases per scene without overwriting.- Live ghost preview: Renders a translucent green mesh of the target prefab at its snap location before placement.- Toggle placement: One-click place or remove connected prefab instances with full Undo support.- Persistent filters: Range slider, text search, and placement-state toolbar in the Snap Context Window remember their values across editor sessions.- Collapsible groups: Connections organized by target prefab with foldout headers that persist between restarts.- Custom database inspector: Review, edit, and clean stale connections from the Project window without writing code.- Bounds-center snapping: Uses combined renderer bounds for more accurate alignment than raw pivot-to-pivot calculations.- Hidden scene tracker: Maintains placed/unplaced toggle state per connection without cluttering the Hierarchy.- Unique asset naming: Each scan creates a new uniquely named database to prevent accidental overwrites.- Editor-only: Zero runtime scripts, zero overhead in builds.No third-party dependencies. Works with any modular prefab kit.Tested on Unity 6000.4.1f1.used antigravity to write code
