Circular Minimap - Region and Clock

A detailed circular terrain minimap with your position, region name and a 12 hour ingame clock. Press M for the fullscreen world map.

Reveal as you explore
Exploration is ON by default in solo worlds. Reveal the area around you as you travel, with discoveries shared between the minimap and fullscreen map and remembered separately for each world.

Fog of war: Ctrl+F4
While playing a solo world, press Ctrl+F4 to switch modes. No separate Mod Settings mod is required.

• ON: reveal terrain as you travel.
• OFF: show the complete map and stop recording new exploration.

Your choice is saved between sessions and applies to both map views. Turning exploration off keeps your discoveries; turning it back on resumes from your current position. Earlier travel while exploration was disabled is not reconstructed. Keep the entire Exploration folder when updating.

Optional Mod Settings support
Players who already have SN2 Mod Settings can continue using Settings > Mods > Circular Minimap - Region and Clock to change visibility and adjust the reveal distance from 25 to 250 meters (100 meters by default). Ctrl+F4 works without it.

Controls

• M: open or close the full-screen world map in either visibility mode.
• Ctrl+F4: toggle fog of war in a solo world. Your choice is saved.
• F3: show or hide the minimap. Hiding it continues exploration tracking when enabled.
• Numpad + / -: zoom. Arrow keys: pan the full map. Home: fit the whole atlas.
• Escape closes the map and also reaches the game. Time and oxygen continue while the map is open.

Manual installation and updating

• Install UE4SS for Subnautica 2. Save and fully close the game and Vortex.
• Back up CirceHUD, including its Exploration folder. Extract CirceHUD into Subnautica2/Binaries/Win64/ue4ss/Mods.
• Replace the packaged files and keep your existing Exploration data. Keep enabled.txt, enable one version only, and do not replace shared mods.txt.

The final entrypoint is Mods/CirceHUD/Scripts/main.lua. 

Exploration and map coverage
Exploration data is stored locally per solo world, separately from original game saves. Keep the Exploration folder when updating or backing up. Progress saves periodically and at world changes
