On-Together: Day and Night
Bring the island to life from sunrise to starlight.
Day and Night is a BepInEx mod for On-Together that adds a configurable real-time
day/night cycle, dynamic atmosphere, seasonal visuals, and ambient sound. Open the in-game menu
at any time to make the island feel like your own.
Japanese: On-Together campleg in on the day and night, seasons, and environment. F11 is used for setting settings, flow of time, water surface, lighting, autumn scenery, and environmental sound field adjustment.
Highlights
- Watch the world shift naturally through dawn, daytime, sunset, moonlight, stars, clouds, and rain.
- Set the day length to suit your play style—from a fast in-game cycle to one full real-world day.
- See the sky reflected in the sea, with scene lighting that warms up after dark.
- Give the island an autumn makeover: red and gold foliage, leaves that fall, settle where they
land and drift away on the water, crows over the lawn, a harvest moon, and optional Halloween lights.
- Feel a gust cross the island now and then, setting the canopies swaying and scattering the fallen leaves.
- Add daytime cicadas and nighttime insects, each with its own volume control.
- Tune lighting, shadows, weather, water, ambience, and seasonal settings live with the F11 menu.
Installation
- Install BepInEx for On-Together.
- Install the package through a mod manager, or by hand: copy only the package's BepInEx
folder into the game directory. The other files in the package (README, changelog, manifest,
icon, licence) are and do not need copying.
- Start the game. Press F11 to open the live settings menu; press F4 to reload the configuration file.
The mod uses the plugin folder On-Together_Day_and_Night and creates the configuration file
cn.ontogether.dayandnight.cfg.
Troubleshooting
- If an ID-card portrait was saved at night by the original 1.0.0 build, open avatar customization,
make any harmless change, and save once. Existing portraits are stored by the game and are not
regenerated when the mod is removed.
- Set Thunder chance per minute to 0 to disable Day and Night's lightning and thunder. The game's
separate Storm ambience setting is independent.
- If shadows are too demanding for your GPU, lower the shadow atlas size or cascade count in the F11 menu.

Install & use Install: follow the bundled instructions
- Unzip the archive from playbuff and read the bundled readme / instructions first.
- Most mods rely on the game's mod loader — the usual route is a community mod manager (such as r2modman): pick this game, install, and it handles the loader and dependencies.
- For a manual install, put the mod files into the matching Mod / plugins folder inside the game directory.
- Launch the game to confirm it loaded; mods with listed dependencies need those installed as well.
Install locations vary a lot between mods — the bundled readme is the most reliable guide.
Install these first, or the mod will not work:
