Help build the map library
S1napse needs a track map for each circuit to draw the bird's-eye view used in Lap Analysis and Replay, and to detect sectors. If a track is missing or looks wrong, you can record it and contribute it back.
How to record a track map
- 01Get on track in your sim. Make sure S1napse is connected (green dot in the top bar).
- 02Press the REC button in the top bar. It turns red while recording.
- 03Drive a clean lap. No off-tracks, no shortcuts, no cutting. The shape of your lap is the track map. Garbage in, garbage out.
- 04Cross the start/finish line at the end of your clean lap.
- 05Press REC again to stop recording.
- 06The recorded map saves to a JSON file in your S1napse track folder.
A clean lap doesn't need to be a hot lap — speed doesn't matter. What matters is staying on the racing surface, hitting roughly normal lines, and not going off.
How to share it
- 01Find the saved track JSON in your S1napse tracks folder.
- 02Post it in Discord (or open a PR if you're a dev).
- 03Mention the sim and the track name in your message. We'll review and merge it into the next release.
Importing a map someone shared
- 01Press the MAP button in the top bar.
- 02Pick the JSON file.
- 03The map loads and is available immediately in Lap Analysis and Replay.
Tracks that look wrong
If a track map exists but looks misaligned, distorted, or has weird kinks:
- 01Note the sim and track name.
- 02Take a screenshot of the broken map (Lap Analysis tab is good for this).
- 03Post in Discord with the screenshot.
- 04If you can record a clean lap and submit a replacement, even better.
What's needed most right now
Top priority: iRacing tracks and Le Mans Ultimate tracks. Coverage on ACC and AC is much better.
If you race on either of those sims and have a track that's missing from S1napse, you're exactly the person we need.
