How to Disable Fog Completely in Fog Overrides Mod
Turning Fog Off Globally
If you want a completely clear view with no atmospheric haze anywhere, the mod gives you a global toggle rather than forcing you to edit every biome one by one. Open the mod's configuration screen from the main menu or the in-game mod list, then look for the master fog toggle. Switching this off removes fog rendering across the Overworld, the Nether, water, and lava in one step, so you do not need to touch individual biome entries.
Keeping Creative Mode Clear Only
Many players only want fog gone while building in Creative but still want normal atmosphere in Survival. Use the separate Creative-only option instead of the global toggle. When enabled, fog is suppressed only while your game mode is Creative, and it returns automatically the moment you switch back to Survival. This is useful on servers where you build in Creative but play normally afterward.
Checking Your Result
After changing either setting, save the config and reload the world or rejoin the server so the change applies. Fly into a swamp, ocean, or the Nether to confirm the fog is gone. If fog still appears, check that a potion effect fog override is not re-enabling it, since effect-based rules can take priority over the global toggle.
