This guide walks you through opening the base_osm_model.blend scene. Follow the steps in order the first time you configure the project.
- Blender 4.0 or newer – earlier versions may miss geometry nodes or material features used in the scene.
- Blosm makes OSM imports quicker, but the scene already includes prepared data if you prefer to skip add-ons.
💡 Keep the folder structure unchanged. Texture, asset, and OSM links rely on paths relative to the project root.

- Launch Blender.
- Use File → Open… and select
base_osm_model.blendin the repository root. - When prompted to Load UI, keep it enabled to get the prepared workspace layout.
- Save a copy as
base_osm_model_working.blend(recommended) so you always have the pristine source.
The file references resources within assets/. If Blender shows missing data-blocks:
- Go to File → External Data → Find Missing Files… and point Blender to the project root folder.
- Enable File → External Data → Automatically Pack Resources if you plan to move the working
