Realm-Crafting is a free, modern, open game editor designed to create complete experiences.
Realm-Crafting is a browser-based 3D game editor that lets you create interactive worlds,
puzzles, AI systems, gameplay behaviors, and more, without writing a single line of code.
Realm-Crafting uses the powerful open-source rendering engine BabylonJS.
It is aimed at creators, dreamers, tinkerers, gamers.
It's all done by dragging and dropping objects, visual scripts, and effects into a scene.
Build what you want your way.
Whether you want to make a horror game with apparitions, a game of avanture, an RPG with quests and dialogues,
or a simple world to explore with visual effects... Realm-Crafting adapts to your imagination.
Built-in editors allow you to create interactive objects, rich environments, a custom graphical interface,
controllable characters, or even dynamic event systems through a system of logical connection and visual behavioral scripting.
With the Project Manager, start your creations with ease.
Create and edit projects with a clear and intuitive interface.
It’s the first step before diving into the editor and shaping your universe.
Realm-Crafting includes a collection of ready-to-use assets: 3D objects, images, textures, sounds, music, videos and behavior scripts.
You can use them directly in your levels without importing anything, to create a game that works from day one.
You can also import your own 3D models (in (.babylon, .gltf, .glb) but also import your others assets...
To use the 3d objects, drag them onto the stage wherever you want; To use the other assets, drag them into the property fields of the selected object.
Triggers actions when a player approaches, presses a button, or crosses an area.
Adds patrol, chase, escape, or coordination behaviors between NPCs.
Create logic puzzles, switches, codes to crack, or activation sequences.
Implements choice dialogues, reputation, barter, or persuasion systems.
Gives life to creatures with specific behaviors: swimming, flying, wandering, flight, or attacks depending on their species.
Incorporates realistic simulated interactions: pushable objects, moving platforms, gravity or dynamic balance effects.
Behaviors are visual scripts (which are already written) that you apply to your objects to bring them to life by simply dragging and dropping.
They allow you to create interactions, movement, puzzles, intelligence, special effects and others without any code to write.
Choose from an extensive list of behaviors, grouped by categories and make your objects interactive by linking them to other objects via the logical connection system.
You can create this kind of thing :
actions ➜ reactions.
actions ➜ reactions ➜ reactions ➜ reactions... (chain reactions)
Visually connect objects to create advanced logical interactions (e.g., opening a door when a lever is activated, triggering traps, connecting puzzles, etc.).
Objects can be chained together to create cascading effects.
Connections determine the execution of related behaviors.
Sculpt your world with intuitive terrain tools: raise mountains, carve valleys, dig caves, and shape landscapes in real time.
Paint up to 8 terrain textures and blend them smoothly using mix-textures to create natural and detailed environments.
Populate your scene effortlessly with multi-object painting to place grass, trees, rocks, and props in a fast, organic, and seamless way.
Create in-game cinematic sequences with ease.
The Cinematic Editor lets you animate characters, objects, cameras and events on a timeline
to tell stories, introduce levels, or create dramatic moments.
No complex scripting required: everything is visual, intuitive, and designed to help you
build immersive cutscenes directly inside your game world.
Design quests, missions and objectives without writing code.
The Quest Editor allows you to create structured quest flows with conditions, triggers,
rewards and progression logic.
From simple objectives to complex multi-step missions, everything is visual and easy to manage,
making it perfect for RPGs, adventure games or narrative-driven experiences.

The GDD helps you keep a clear vision of your project and makes it easier to plan, iterate, and share your design decisions.
Design dynamic game interfaces such as HUDs, menus, inventories, dialogs, and overlays using an intuitive drag-and-drop editor.
Easily position, resize, and style UI elements, then bind them to gameplay logic to create responsive and interactive user experiences.
Create advanced visual effects using a powerful and visual particle editor.
Control emitters, sub-emitters, blend modes, animation sheets, and effect behaviors with a real-time preview to fine-tune explosions, magic, smoke, fire, and more.
Create and customize unique characters by combining models, accessories, and animations.
Assign behaviors, equipment, and interactions to fully control how actors look, move, and react inside your game world.
Create your own behavior scripts to customize your worlds — for yourself or to share with the community.
You can also extend or refine the ones already included. An SDK is available to make creation even easier.
Scripting is completely optional: Dozens and even hundreds of ready-to-use behavior scripts are already included..
And if you decide to dive in, the integrated script editor is here to help, with real-time error feedback and a simple, beginner-friendly interface.
