This feature changes audioNameHash in vehicles.meta for one or more vehicles from Scanner results.

Apply a built-in or known sound

1. Open Sound after scanning.
2. Select vehicles individually or use Select All.
3. Enter part of a name under Apply to selected.
4. Choose an autocomplete result (up to ten are shown) or enter a hash manually.
5. Click Apply. This fills New Sound but does not write to disk.
6. Review every row and click Save to Disk.
7. Confirm the number of vehicles being changed.

You can also enter New Sound per vehicle. When saving, every row with a non-empty New Sound value is processed, even if its checkbox is no longer selected.

File writes

• Updates are grouped by vehicles.meta path.
• A .bak file is created for each file before it is modified.
• Only items whose model names match are updated.
• The result reports successful and failed updates.

Custom sounds

Changing audioNameHash does not install audio. A sound resource containing AUDIO_GAMEDATA, AUDIO_SOUNDDATA, optional AUDIO_SYNTHDATA, and AUDIO_WAVEPACK must be present and started before the vehicle.

Use Sound Pack Builder to combine custom sounds. After saving, restart the sound and vehicle resources, then test idle, rev, acceleration, deceleration, horn, and distance behavior.

Troubleshooting

• No change: verify the hash spelling/case, resource start order, and that the server uses the edited copy.
• Some updates fail: model names may be stale. Rescan after a rename or file change.
• Silent or incorrect sound: validate the sound files and manifest, not only the audioNameHash value.
