Subnautica: Below Zero
Motion-control port of the SubmersedVR approach for Below Zero's snowy Arctic dives.
The catch: Conflicting documentation: install notes are from 2023 and the latest release defers to another repo.

Stuck?
The 0.8.0-bz release page points to a separate repository for the latest Below Zero builds, which I could not open
Reported on the creator's page or the linked sources. Known issue
Fork README text still says the mod does not work with Below Zero yet; steps above come from the 0.7.0-bz release notes
Reported on the creator's page or the linked sources. Known issue
Black screen in the headset
This mod runs through SteamVR. Start your link (Quest Link, Air Link or Virtual Desktop) first, then SteamVR, and only then the game. If SteamVR shows the headset but the game is flat, close the game and launch it again the way the creator's steps say. General tip from us
Controllers don't show up
Start Link, Virtual Desktop or SteamVR before the game, and make sure the controllers are awake before launch. General tip from us
Stutter or low frame rate
Lower the in-game resolution or render scale first, then shadows and volumetrics. Close overlays you don't need. General tip from us
The mod didn't load at all
Recheck the game version against the creator's page; a game update is the most common cause. Then reinstall the mod files. General tip from us
