01. Unified 3D World Editor

Stop juggling disconnected tools and disjointed window systems. World Builder unifies every aspect of scenery authoring into a clean, modern canvas.

• Layers, Not Silos: Unified scene tree covering Imagery, Terrain, Overlays, Landmarks, and Airports with independent visibility and locking.
• Multi-Mode Projection: Switch instantly between top-down 2D Map, Satellite aerial context, and a full interactive 3D Viewport.
• Look Modes: Inspect your work in full Render (simulation lighting, sun angle, and atmosphere), Clay (pure geometry), or Wireframe modes.
• Interactive 3D Gizmos: Standard translate, rotate, and scale transforms with customizable snapping and ground-clamping.
• Live Simulator Sync: Follows your aircraft position and camera in X-Plane directly in the 3D editor, take screenshots and save them in your project

02. Modern Airport Builder

Designed as the modern, 3D successor to Laminar’s legacy World Editor (WED), completely free for airport authors and community contributors.

Free in World Builder Basic!

• Full WED XML Round-Trip: Seamlessly open and export WED XML files without losing hierarchy, metadata, or airport structure.
• Scenery Gateway Ready: Direct airport discovery, download, editing, and submission workflows for Scenery Gateway contributors.
• Runway & Taxiway Layout: High-precision bezier curves, taxi lines, hold-short bars, runway markings, and surface lighting.
• Default Asset Library: Instant search, category browsing, and 3D placement of all default X-Plane ramp and terminal equipment.

03. Built-In 3D Model Builder

Stop leaving the scenery editor just to build a custom tower or terminal. A dedicated procedural 3D modeler crafted specifically for X-Plane.

You can use your AI assistant connected to World Builder ONE to create models for you and tweak them in Model Builder.

• Native OBJ8 Authoring: Build clean, draw-call optimized 3D geometry with booleans, bevels, extrusions, and repeaters.
• Import 3D models from major formats such as Blender, 3DS, USDZ, FBX and GLB. You can even drag an external model straight into the 3D world.
• Reference Photo Sampling: Import real-world photographs to sample calibrated color palettes and match authentic materials.
• Automated Night Lighting: Generate corresponding emissive night (LIT) textures with customizable window patterns and rooftop beacons.
• UV Atlasing & Packing: Automatic UV projection and multi-texture atlas compilation designed for optimal flight sim frame rates.

04. Complete Overlays & Autogen Engine

OpenStreetMap data import and customization. Assign your custom assets to each OSM feature tag and let the build system do the rest!

Populate in minutes your scenery with thousands of overlays, from buildings to forests. Use default X-Plane assets, third party libraries or your custom assets created with Model Builder or generated by AI.

• Download the OSM data for your scenery, assign default and custom objects to each OSM feature. Buildings, Roads and Networks, Forests, Walls and Edges, Water and Coastlines, Land use and Towns.
• Every Overlay Primitive: Objects (.obj), Facades (.fac), Forests (.for), Lines (.lin), Strings (.str), Draped Polygons (.pol), Autogen points/strings/blocks (.agp, .ags, .agb), and Beaches (.bch).
• Autogen Town Zones: Draw and configure custom zoning boundaries to govern local residential and industrial building generation.
• Non-Destructive Operators: Parametric repeaters, cloner arrays, and object scatterers that stay fully editable throughout your project.
• Granular Exclusion Perimeters: Target exclusions specifically by family (objects, facades, forests, polygons, or networks) without wiping unintended layers.

05. Terrain Mesh & Orthophotos

Take full control of the earth below your aircraft with precision mesh tools and aerial photography management.

• Interactive Mesh Sculpting: Elevation brush, contour flattening, slope calculation, and edge smoothing to eliminate jagged runway terraces.
• Aerial Imagery Ingestion: Ingest local high-resolution geotiffs or connect aerial imagery services with your own provider API keys.
• Seasonal Look Editor: Preview and calibrate multi-season ground transitions (summer, autumn, winter, snow) directly in the viewport.
• Seam & Water Repair: Tools to repair cloud occlusions, seam lines, and water body perimeters.

06. Packaging & Standalone Installer

Distribute your scenery effortlessly without forcing your users to manually edit scenery configuration files.

• DAG-Based Build Pipeline: Incremental compilations with honest error reporting, cancel support, and clean state tracking.
• Pack Validation: Automatic checks for missing textures, broken library references, and DSF file consistency.
• Standalone Installer Generation: Build self-contained installers that automatically detect user X-Plane directories and configure priority order in scenery_packs.ini.

07. AI Integration

The industry’s first AI-native flight simulation studio. Exposing all application tools to external AI through the Model Context Protocol.

Learn more…

• Conversational Landmark Creation: Ask your AI assistant to model a real-world monument, assign textures, and position it accurately.
• OpenStreetMap Compilation: Direct your assistant to extract OSM building footprints, roads, and landuses into compiled scenery.
• Automated Layout Auditing: Have AI scan your airport layouts for intersecting taxiways, misaligned markings, and Gateway rule violations.
• Custom Creation Skills: Compose repeatable multi-step automation scripts for large-scale regional scenery projects.
