HTFDayNight
A full day and night cycle: real sunsets, a galaxy night with a glowing moon, and an ocean that mirrors the sky.
About this mod Author’s original text
HTF Day and Night
A full day and night cycle for How to Fish.
The endless noon becomes a living sky: the sun arcs overhead and sinks into
the sea through a burning sunset, stars and a galaxy wheel across the night
with a glowing moon, and dawn brings the sun back out of the water. Shadows,
golden-hour light, moonlight, clouds, fog and even the ocean's reflections
all follow the cycle - and everything returns to normal the moment you quit.
Features
- Sun that rises, crosses the sky and truly sets - with golden hour light
and moving shadows on everything in the world
- Night: a painted galaxy (stars, milky band, dust rift, nebulae), a glowing
detailed moon that rises as the sun sets, moon-shadows, darkened clouds
- Smooth dusk and dawn transitions - sunset burns over the sun's grave and
cools on the opposite horizon
- The ocean mirrors the live sky: molten at sunset, ink at night
- Works everywhere in the world, on every island, while sailing
- Time controls: hold Right Arrow to fast-forward time, Left Arrow
to rewind (configurable)
- Day length configurable (default: one full day = 20 real minutes)
- Menus stay untouched; everything restores on quit
- Co-op synced: time rides the game's own server tick - every player sees
the same sky, joiners are correct instantly, zero network traffic
- Arrow keys in co-op shift only your own view; F9 resyncs you exactly
- Underwater fog is never touched - diving looks as the game intended
Installation
With a mod manager (easiest)
- Install r2modman or the
Mod Manager.
- Select How to Fish, search for HTFDayNight, click Install
(BepInEx is installed automatically as a dependency).
- Press Start modded.
Manual
- Install BepInEx 5 x64 into
the game folder - the one with How to Fish.exe
(Steam: right-click the game, Manage, Browse local files).
- Run the game once and quit, so BepInEx creates its folders.
- Copy HTFDayNight.dll and htfsky.bundle into
How to Fish/BepInEx/plugins. Both files must sit side by side.
Then just play. You spawn at noon; sunset begins after a few minutes
(or hold Right Arrow to see it now). Nothing needs enabling in-game.
Configuration
After the first run, edit BepInEx/config/yoxi.htf.daynight.cfg:
| Setting | Default | Meaning |
| --- | --- | --- |
| MinutesPerDay | 20 | Real minutes per full day |
| TimeBackKey | LeftArrow | Hold to rewind time (None to disable) |
| TimeForwardKey | RightArrow | Hold to fast-forward (None to disable) |
| TimeScrubSeconds | 8 | Holding a key crosses one day in this many seconds |
| ResyncKey | F9 | Drop your personal time shift, rejoin the shared clock |
| MoonlightIntensity | 0.35 | Strength of the moonlight at full night |
| MoonlightColor | #9EB3EB | Hex colour of the moonlight |
| FogColor | #080D1A | Night fog colour above water |
| FogDensityMultiplier | 2.0 | Night fog density as a multiple of the day's |
Compatibility
- Works with the HTF custom-map loader: maps that carry their own sky
automatically defer to this mod.
- Contains no game assets: the entire sky (meshes, textures, shaders) is
generated content shipped in htfsky.bundle.

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:
