The October 4 RIAutomobility updates give new installations H as the default seat-switch key. It avoids Minecraft’s G shortcut and Momentum’s cruise-resume key on R.
Already have your own controls? Existing bindings stay as you saved them. Choose H manually in Minecraft’s Controls menu if you want the new layout.
RIA 0.1.0-unofficial.9 is available for Minecraft 26.1.2 and 26.2 with their matching Automobility 1.0.0-beta.1 builds. For the new 26.3 Automobility beta, use RIA 0.1.0-unofficial.10. The earlier 26.3 RIA .9 file remains available for the older Automobility core.
The 26.3 .10 update changes the required core version; it retains the gameplay and assets from .9. Existing vehicles, server-checked seat switching and the lorry’s 54-slot cargo remain. This update adds no new vehicle models.
Install matching RIA and Automobility files on server and clients. Momentum is optional. Pick the Minecraft version first, then the compatible pair; the RIA download lists its required Automobility build.
