fml2blender

Convert Floorplanner floor plans to Blender 3D scenes.

Before (Floorplanner):

After (Blender):

Features

• 🏠 Walls with textures and proper thickness
• 🚪 Windows & Doors with automatic wall cutouts
• 🪑 Furniture positioned and scaled correctly
• 🎨 Materials including textures and colors
• 🏗️ Multi-floor support

Quick Start

1. Install

pip install fml2blender

Or install from source:

git clone https://github.com/daviddemeij/fml2blender
cd fml2blender
pip install -e .

FML files contain floor plan data used by Floorplanner. You can capture them from various website that use floorplanner such as real estate listing websites like Funda.nl

From Floorplanner.com

1. Open your project on floorplanner.com
2. Open browser DevTools → Network tab
3. Filter by fml or XHR
4. Reload the page and you'll find one response for each floor (the 1st floor is generally the first request)
5. Right-click → Copy Response → Save as floor1.fml. Do this for each floor.

From Funda.nl

1. Open a listing with an interactive floor plan
2. Open browser DevTools → Network tab
3. Click "Plattegrond" to load the interactive floorplan
4. Filter by fml
5. Save the fml file (usually one file for all floors)

3. Download Assets

fml2blender harvest /path/to/project

This parses your FML files and downloads:

• 3D models (GLB) for furniture, windows, doors
• Textures (JPG/PNG) for walls and floors

Assets are saved to assets/ and a manifest.json is created.

4. Build Blender Scene

fml2blender build /path/to/project

This runs Blender in background mode and builds the 3D scene.

Options:

fml2blender build /path/to/project --gui          # Open in Blender GUI
fml2blender build /path/to/project -o scene.blend # Save to file
fml2blender build /path/to/project --level-height 3.0  # Custom floor height

Project Structure

After harvesting, your project directory should look like:

my-house/
├── floor1.fml          # Ground floor
├── floor2.fml          # First floor
├── floor3.fml          # Second floor
├── manifest.json       # Asset ID → file path mapping
├── products.json       # Product metadata (dimensions, names)
├── materials.json      # Material metadata (colors, PBR maps, tiling)
└── assets/
    ├── abc123.glb      # 3D models
    ├── def456.glb
    └── texture.jpg     # Textures

Requirements

• Python 3.10+
• Blender 4.0+ (for build command)
• For legacy GLB v1 assets (rare older windows/doors), install Node.js and gltf-pipeline so harvest can auto-upgrade to glTF 2: npm i -g gltf-pipeline

The harvest command only needs Python. The build command requires Blender to be installed.

How It Works

1. Harvest: Parses FML JSON files to extract asset IDs, resolves them via Floorplanner's search API, downloads GLB models and textures from their CDN.

2. Build: Runs inside Blender to:

   • Create walls from line segments with proper thickness
   • Apply wall textures to left/right sides
   • Import GLB models for furniture and openings
   • Cut holes in walls for windows/doors
   • Set up glass materials for transparency
