OpticManager
by creativemd
With OpticManager installed, a server owner can change how long a day lasts, how bright the night is, and how the day-night cycle is timed.
What it does
OpticManager adjusts the day-night cycle through configurable values: the length of day and night, the light factor and brightness at night, and the time of day. Those settings can be synchronized from the server to connected clients, so the client-side configuration matches what the server uses. Players can also toggle a visible nametag and hide chat through the mod's options.
The mod is aimed at server owners and modpack builders who want a different pacing for the day-night cycle, and it notes that it works with a modified cycle and with mods that change behavior around sleeping. Only administrators can change the configuration. OpticManager needs CreativeCore and Fabric API, runs on the client and the server, and is published for Fabric, Forge and NeoForge for 1.18 – 26.3, under the GNU Lesser General Public License v2.1 only, so it is open source.
Key features
Day and night length
Lengths of day and night can be set separately, changing how quickly the cycle moves.
Night light and brightness
The light factor and brightness at night can be tuned to make darkness lighter or heavier.
Synchronized client settings
Settings configured on the server are passed to clients, so both sides keep the same values.
Nametag and chat options
A nametag can be made visible, and chat can be hidden, through the mod's configuration.
