With the use of a special import&export script, BTG files can be opened in and exported from Blender. This makes it possible to edit FlightGear's terrain and specifically airports in a visual editor.
User documentation
Installation
Download the two scripts:
Place both files in your Blender's .blender/scripts/ directory. Common locations are:
- Windows: C:/Program Files/Blender Foundation/Blender/.blender/scripts
Usage
Import a .btg file (note: you'll have to unpack .btg.gz files first!) via File > Import > Simgear (.btg).
When exporting, via File > Export > Simgear (.btg), make sure to enter the correct coordinates and radius, as displayed in the console and screen on import.
Known issues
- Textures are not applied automatically in Blender.
- No textures at all on terrain import. Terrain is imported as one big mesh, despite various materials.
- Terrain is not lined up with the axis, making it hard to edit correctly.
- Airport lights are not imported.
- Imported meshes are shrinked.
