Build massive 2D worlds 10x faster. Render 100+ scenes with zero editor lag using Proxy Mode. Fast prefab & room placement, plus seamless multi-scene management.Compatible with 2022.3+ versionsIf you're using later versions and ask to update the APIs on import then do so. The toolkit is designed to work on both older and newer APIs2D Multi Scene Level Designer PRO: is a toolkit built to remove the bottlenecks of creating massive 2D worlds. If you are building a Metroidvania, a RPG, a large open world, or platformer, you are bound to face a problem: loading many scenes at once drops the Unity Editor to very low FPS, and moving prefabs across scene boundaries becomes slow and tedious.This toolkit solves that with zero-cost Proxy Rendering, a World Palette for rapid placement, and bulk Scene Movement tools, letting you work on huge worlds smoothly while still seeing the full layout.🚀 Zero-Cost Proxy ModeEliminates Editor lag by replacing heavy tilemap scenes with lightweight color-coded rectangles drawn using GL calls.Work with 50+ scenes loaded simultaneously while keeping smooth Editor performance.Maintain a bird’s-eye view of surrounding rooms while editing the active scene normally.Proxy data automatically updates every time a scene is saved.🎨 World Palette ToolA customizable Scene View HUD for drag-and-dropping prefabs and full room templates.Smart Scene Targeting: Automatically places objects in the correct Unity scene based on cursor position.Create multiple Collections and Profiles (Forest Props, Dungeon Enemies, Traps, etc.).Rotate objects quickly using the Ctrl key before placement.📦 Move Multiple Scenes ToolMove multiple scenes at once, bypassing Unity’s default limitations.Reposition dozens or even hundreds of scenes as easily as moving a single object.Advanced selection modes: Rectangle, Freehand Lasso, and Axis Constraints (for example, select everything to the right).Fully compatible with Unity’s Undo/Redo system.🛠️ Workflow & Quality of Life FeaturesQuick Scene Activation: Ctrl + Click a proxy or object to instantly set its scene as active.Quick Cleanup: Shift + Double Click a scene proxy to unload it instantly.Auto-Unload on Play: Non-active scenes unload automatically when entering Play mode for faster testing.Global Grid Overlay: Customizable alignment grid for precise level design.💡 Use CasesMetroidvanias / Large Open Worlds: Design your full map layout using Proxy Mode with biome color grouping.Rapid Prototyping: Instantly place pre-configured room templates from the World Palette.Expanding the Map: Shift entire sections of the world to create space for new areas or boss rooms. ✨- This toolkit is a far superior version of the now deprecated 2D Multi Scene Level Designer It offers 50-80% more performance compared to the previous depracated versions. - Older users can upgrade to the new version.REQUIREMENTSMinimum Unity Version: 2022.3 LTS +Pipeline Support: Built-In, URP, HDRPSetup Requirements: Out-of-the-box, it relies on a specific tag-based hierarchy structure for level detection (Default Tag: MainLevelTileset), which can be fully modified via the WBSettings asset.DEPENDENCIESNo external dependencies or packages required.ARCHITECTURE & PERFORMANCEEditor-Only Toolkit: Designed primarily as an editor tool; it is non-intrusive on runtime builds, utilizing minimal runtime data (ScriptableObjects for Proxy Data and Settings).High-Performance Rendering: Uses Unity handles (Handles.DrawSolidRectangleWithOutline()) and low-level OpenGL (GL) calls to ensure extremely fast rendering regardless of actual tilemap complexity.Frustum Culling & Chunking: Implements spatial chunking and frustum culling on baked proxy geometries so editor performance scales predictably even with hundreds of scenes loaded.Smart Bounds Detection: Calculates scene boundaries automatically using a fallback system (CompositeCollider2D, transformed Tilemap bounds, or Renderer bounds) for precise smart-targeting during prefab placement.Automated Baking System: Automatically generates and saves TilesetProxyData assets directly to your project when scenes are saved.Undo Integration: Fully integrated with Unity’s native Undo/Redo tracking via serialized state holders, ensuring destructive multi-scene manipulations can be safely reverted at any time.
