Aeronautics Replay
Adds ReForgedPlay support for Aeronautics ships and contraption
About this Mod
Aeronautics Replay
What this mod does
A simple mod that enables replay support for Aeronautics contraptions in ReForgedPlayMod
Adds a small bridge layer that watches for Aeronautics/Sable custom payloads and injects them into the ReplayMod recording stream, so ships move correctly when you watch a replay back.
Configuration
Controls how often snapshotIntervalTicks are saved into ReplayMod recordings.
1 (default)
Every snapshot is saved. Fastest sublevel realignment on playback.
20+
Smaller replay files. Sublevels may take slightly longer to realign on playback.
If ships take 1–2 seconds to snap into position at the start of a replay, set this to 1.
Known limitations
A short realignment delay at the start of replay playback is expected — the sublevel initialization packets need to be processed before ships can start moving.
ReForgedPlayMod is required.
Currently in beta. Bugs may occur.

Server lagging with Aeronautics Replay – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Aeronautics Replay consumes the most tick time.
