Runtime Studio

Runtime Studio - Runtime Editor Framework

Building an in-game editor takes months. You need to handle UI, object selection, transform gizmos, saving systems, and ensure players cannot break your game.

Runtime Studio provides a fully functional, player-safe editor out of the box, allowing players to create, edit, save, and load levels directly within your live game.

Give players a complete level editor inside your game in minutes instead of spending months building one.

It also supports exporting and importing levels, making it easy for players to share creations through external files.

The core system is intentionally generic, offering a clean and professional interface without requiring you to rebuild your project architecture.

Powerful Editing Workspace

Give your players a familiar and powerful workspace.

Runtime Studio includes a UI Toolkit-based shell with Hierarchy, Project, and Inspector panels. Players can interact with scene content using action panels, a console overlay, and a smart object picker.

Runtime Scene Editing

Editing levels feels intuitive and familiar.

Players can build worlds using Move, Rotate, and Scale tools with transform gizmos, free camera controls, grid overlays, snapping, and live asset previews.

Player-Side Custom Components

You control exactly what players are allowed to edit.

Runtime Studio includes runtime inspectors for many common Unity components, allowing players to interact with gameplay systems directly inside the editor.

You can also expose custom gameplay components like Health or Spawners by integrating them into the runtime inspector, with full control over how they are presented and edited.

Runtime Play Mode

Test levels instantly by switching between edit and play mode.

Runtime Studio includes a built-in Play Mode that allows players to switch from editing into gameplay. Players can run their level in real time, test mechanics, and experience their creation as a game, then return back into editing to make adjustments without losing progress or context.

Save, Load, and Share

Player-generated content needs a reliable way to be stored and distributed.

Runtime Studio includes a complete runtime save and load system. Creations can be exported as compressed package files, allowing players to share custom levels via external distribution.

Curated Asset Libraries

You decide exactly what assets players can use.

The Editor Asset Library lets you group prefabs, meshes, materials, and audio. Players can browse these curated assets in the runtime Project panel with automatically generated previews.

WebGL Support

Run and share user-created content across platforms.

Runtime Studio supports WebGL builds, allowing your runtime editor and gameplay systems to run in browser-based environments. Level export and import is fully supported through compressed package files, enabling players to transfer creations between sessions and platforms using external file handling.

Built-In Undo and Redo

Mistakes happen.

Players can safely undo or redo edits, including transform changes, component edits, object duplication, and hierarchy modifications.

Extensible Framework

Build and expand the editor to fit your game.

Runtime Studio is a modular, extensible framework that allows you to add custom tools, components, and workflows. Extend the runtime interface with your own systems or create new editor features through plugins or direct integrations, tailored to your project’s needs.
