The Sandbox of Infinite Possibility
Welcome to the Kellians World Map Builder—a professional, browser-based 3D workspace where absolute design freedom meets multiplayer reality. Here, you aren't just adjusting shapes; you are designing environments where players can interact, shops can trade, and games can be played.
Every builder starts with their own 3D plot of land. Using our custom Three.js editor engine, you can extrude walls, paint terrain elevations, drop custom furniture props, and use advanced tools like AI Floorplan Generators to lay down blueprint designs instantly.
Once you hit SAVE MAP, your changes sync in real-time. Any player exploring the live multiplayer world can walk straight onto your plot, jump onto the roofs you've elevated, sit on your benches, and buy items from your customized storefronts!
Real-Time WebGL Sandbox
Plot Boundaries
You begin with a default size plot grid. Expand your boundaries using the Expand action tool to give yourself extra building canvas!
Physically Active Roofs
Collision meshes are constructed automatically. When you build walls, columns, or rooms, players in the multiplayer world can walk, jump, and run directly on top of them.
AI storefronts
By placing a Shop entity, you can run a custom digital store where other players can spend Kelcoins. Add custom image signage and design custom dimensions.
Camera Controls
Rotate the viewport around your map focus. Right-click and drag to pan, and scroll your wheel to zoom in and out.
Structure Builder
Construct a curved span by clicking two separate points on the map. Excellent for entrances and grand gates.
Drop vertical support pillars. Great for structuring porches, temple entryways, or building edges.
Erect flat walls. Can be customized with custom textures. Adjust thickness, length, and height to fit.
Insert transparent glass window frames. Frame textures can be adjusted using the texture tool.
Place doorways to rooms. Supports custom scaling and standard textures.
(Business Plots Only) Place digital billboard panels. Configure text, image links, and redirect URLs.
Drop fully-featured custom 3D models (GLB). Upload your own creations or pick from the default asset library.
Open a catalog of internal furniture and scenery props: beds, sofas, lamps, baths, round rugs, arcade units, and pool tables.
Place a compound solid building volume featuring doors, steps, and automatic roof floors that player characters can scale and explore.
Build a commercial storefront. Set a shop name, customize signage, choose sell options, and trade items with other players for Kelcoins.
Quickly design a room layout by dragging a boundary box on the ground grid to extrude a roofless building template instantly.
Ground Cover
Place textured flat surfaces on the ground. Customize the surface texture, scale, width, length, rotation, and opacity using the selection controls.
Landscape & Water
Span picket-style fences along borders or yards. Custom textures can be applied to change the color/material.
Grow lush hedgerow boundaries. Blocky foliage boundaries that match standard landscaping gardens.
Place barricades or custom security gates. Combine with fences to seal your garden borders.
Sculpt the actual heightmap terrain! Click and drag upwards to form hills and peaks, or downwards to dig deep trenches.
Place an excavated swimming pool complete with custom liquid water shaders. Scale to any size.
Paint physical bodies of water. Perfect for building custom lakes, wrapping canals around buildings, or making fish ponds.
Actions & Commands
Select any placed object to modify it. Selected objects display custom handles/gizmos for position dragging and reveal the properties sidebar.
Selects every single object on your plot simultaneously. Great for bulk deletions or general scaling operations.
Expands your overall plot borders to widen your building space. All objects are shifted automatically to align relative to the new workspace.
Instantly deletes whatever items are currently selected. Can be reverted using the Undo function.
Revert your last placements, movements, modifications, or deletions step-by-step using the session history stack.
Opens the texture selection pane to apply tiles, woods, brick walls, and concrete textures onto highlighted or selected meshes.
Let the AI helper draw out a full building floorplan blueprint dynamically. Great for getting instant layout inspiration.
Clear your entire plot, deleting all placed items, segments, and structural meshes to start building from scratch.
Viewport & Settings
Toggles the standard grid overlay on the floor. Useful for ensuring architectural alignments and sizing bounds.
Hides any walls that are directly facing the camera (Sims-style). Crucial for decorating or viewing rooms internally.
Fades the entire scene into a wireframe model layout. Allows you to check overlapping bounds, select complex meshes, or inspect alignment details.
Opens the feedback forum directly in the editor. Send recommendations for new tools, report bugs, or upvote ideas.
🔄 Rotation (Yaw, Pitch, Roll)
Every placed object can be spun 360 degrees around its vertical center. Adjusting rotation ensures alignments and matches doors and columns to walls.
- Standard range: 0° to 355° in increments of 5° for rapid snapping.
- Precision objects: Billboards support exact 1° angle modifications.
- Atmospheric positioning: Sky Planets feature both azimuth (yaw rotation) and elevation (pitch rotation) sliders so they can hover anywhere in the horizon.
📐 Sizing & Dimensional Extrusion
Unlike basic grids, the builder lets you stretch components along specific axes rather than forcing uniform scaling.
- Scale: Sets the global volume multiplier uniformly (e.g. shrink props to 0.4x size or expand models to 10x size).
- Width, Depth & Length: Stretches structural blocks (walls, roads, pools, shops, quickbuilds) along their X and Z coordinates without distorting boundary meshes.
- Height: Extrude room outlines, shops, columns, and walls higher or lower to build multi-floor structures.
🛗 Height Hover & Elevation
Need objects to float, hover on walls, or sit on upper roofs? Elevation sliders lift meshes cleanly off the floor coordinates.
- Plot Elevation (Hover): Found in the top toolbar. Setting this lifts the entire plot ground, eliminating gaps and creating hovering structures.
- Item Elevation (Hover): Lift individual props (e.g., picture frames, celestial planets, or lights) off the ground grid.
- Roof Collisions: Placing items on rooftops automatically snaps them to the roof height, allowing walk zones.
Drag & Drop Repainting
Repainting walls, fences, windows, and floors is fully visual. Open the 🎨 Textures panel on the right side of your editor.
Choose any thumbnail texture (brick, concrete, shingles, wooden tiles, steel plates), click and hold, then drag your mouse directly over the 3D scene grid.
All paintable objects in your plot will glow with a violet highlight. Hover over a highlighted surface, release your mouse button, and the texture applies instantly!
Custom Image Uploads
Want a unique wallpaper, your company logo, or specific brick patterns? You can upload custom images from your hard drive.
In the textures panel, drag and drop any image file (JPEG, PNG, WebP) directly into the dashed upload dropzone, or click the dropzone to browse your computer.
The image is automatically parsed and added as a custom thumbnail in your texture grid, ready for immediate mapping onto walls and items.
🪄 Gemini AI Texture Maker
Can't find the perfect texture pattern? Generate seamless custom textures dynamically using Gemini artificial intelligence.
Simply type what you need (e.g. "weathered red roof tiles", "cyberpunk glowing cyan circuit lines", "ancient mossy oak floorboards") into the prompt field and click Gen.
The AI generates a seamless texture on the fly, uploads it to your personal library, and adds it to your thumbnails grid for placement.
🍂 Dynamic Seasons & Particle Effects
Change the seasonal environment of your plot with a single click. The builder renders unique shaders and custom particle effects for each season:
- ☀️ Summer: Default mode. Bright sunshine, lush green grass, and full leaf foliage on trees.
- 🍂 Autumn: Renders warm golden-orange shades across the terrain and trees, accompanied by falling leaf particle systems that blow with the wind.
- ❄️ Winter: Blends snow overlays onto all objects and surfaces, triggers realistic falling snow particle systems, and casts a cool, frosty atmosphere.
🌍 Environment & Weather Sliders
Control the atmosphere of your space dynamically using fine-tuned environment inputs inside the Dropdown menu:
- ☀️ Day / 🌙 Night: Transitions the world from midday brightness to deep night. At night, light-emitting objects (streetlights, neons, window textures) automatically illuminate.
- ☁️ Clouds: Adjusts the density and visibility of the clouds traveling across the sky dome.
- 🌧️ Rain: Increases rain particle density, introducing misty atmospheric fog.
- 💨 Wind: Elevates wind speed, causing leaves, snow, and rain to blow sideways, while increasing vegetation movement.
- ⚡ Thunder: Controls storm intensity, triggering sudden bright lightning flashes that temporarily illuminate the scene.
- 🌊 Water Depth: Changes the elevation level of water planes, allowing you to flood canals, build deep lakes, or raise dry land.
🎨 Custom Sky Color Customization
Toggle the Custom Sky Colors switch to override the default procedural sky dome and design your own personalized aesthetic:
- 🌌 Zenith Color: Sets the color of the sky dome at its highest vertical point.
- 🌅 Horizon Color: Determines the sky color near the floor horizon line.
- 🌫️ Fog Color: Adjusts the color of distance fog blending into the horizon.
- 💡 Ambient Color: Controls the color of ambient environmental bounce lighting cast on objects.
- ☀️ Sun Color: Defines the direct highlight color of the main directional light source.
🚀 Plot Hover Height & Performance
Control the elevation of your entire plot in the world and optimize performance metrics dynamically:
- 🚀 Hover Height Slider: Elevates your entire plot grid above the standard ground plane (from 0 to 100 meters). Perfect for designing floating castles, high-tech flying airships, or isolated platforms. Players can teleport or use ladders to reach elevated platforms.
- ⚡ High Perf vs 🐢 Low Perf Toggle: Activates or deactivates complex lighting pipelines. High performance mode utilizes realistic soft shadows, volumetric lighting, and dense environmental particle overlays. Low performance mode optimizes memory consumption and shadows for a smoother experience on low-end hardware.
