This is Cloud Control to Major Sam...
This mod adds the /toggle_clouds chat command which can control whether clouds are enabled on per-player basis. Hiding the clouds can be useful for removing obstructions and improving visibility if you are building large structures that stretch above the clouds, and being able to toggle it on the fly with a chat command makes it convenient to disable and then enable clouds again for temporary visibility improvement.
The /toggle_clouds command only takes effect for the player who calls the command, and the mod persists this preference for each player across server sessions. It is perfect for installing onto a creative multiplayer server to allow players to toggle cloud visibility for themselves.
The built-in engine setting enable_clouds is planned to be removed in Luanti 5.11 (#15633) in favour of putting cloud visibility fully in control by the API. This mod serves as a drop-in replacement for those wishing to still disable clouds in a game that does not already offer the option to.
