Sable Replay Compat
Sable Replay Compat is a NeoForge compatibility mod that lets ReplayMod record and replay moving Sable SubLevel contraptions, which otherwise stay frozen in replays.
What it does
Sable moves its physics bodies, called SubLevels, by sending their pose data through a separate UDP channel rather than the regular Minecraft connection. While ReplayMod records, that data never reaches the replay file, so contraptions appear fixed on playback. This mod sends the pose data over the standard channel instead, so it is captured and replayed.
The mod routes the connection through NeoForge's checks during replay so the world loads. It works with the Sable physics engine and the reforgedplaymod build of ReplayMod, and it is open source under the GNU General Public License v3.0 or later. Files target 1.21.1 only, and the latest NeoForge file is 1.0.0, published 2026-06-03.
Key features
Moving contraption recording
SubLevel contraptions keep their movement while a replay is recorded, so ships and machines move again in playback.
Pose data rerouting
Sable pose data is sent over the standard channel during recording, not a separate UDP channel that replays drop.
Quick mode fix
Replay quick mode loads the world without getting stuck on the Reconfiguring screen.
Fresh recordings only
Old replays recorded without the mod carry no movement data, so their contraptions stay frozen; a new recording is needed.
