# Grand Tourer — Evolution

Open `nightdrive-evolution.blend` directly to edit the final source. The `Portfolio Evolution` scene contains individually editable bodywork, louvers, wheel vanes, wing and marker housings. The original source in the parent folder was not overwritten. No external assets or paid services were used.

`export-grand-tourer.py` exports the loaded `Portfolio Evolution` scene into eight joined material groups, without lights, cameras, textures or animation. Execute it inside Blender with `__file__` set to the script path. The web renderer sanitizes Blender's duplicate-name suffixes before assigning its runtime lighting behavior.

Design history:

1. The original source scene was appended from `../nightdrive-grand-tourer.blend` and named `Portfolio Evolution`.
2. `refine-grand-tourer.py` applied the first paint, hub, louver and deck-lip pass. This first pass is historical and should not be reapplied to the finished source.
3. `add-personality.py` added the swept wing, mounted cyan guides and turbine wheel faces. This second pass replaces its own `signature-` objects on repeat runs.

To reproduce from the original, follow that order in a separate scene. For ordinary editing, use the finished `.blend` and export script. Asset counts and provenance are recorded in `nightdrive-evolution.asset.json`.
