2D Multi Scene Level Designer: 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 Mode
- Eliminates 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 Tool
- A 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 Tool
- Move 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 Features
- Quick 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 Cases
- Metroidvanias / 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. ✨
