In constant development!


A mod made with love for you guys <3
In a 3-step nutshell:
- A player sleeps
- MADE IN HEAVEN!!!
- honk mimimi hooonk mimimimi
Seamless Sleep is a server-client mod that turns going to bed into a smooth, in-world transition instead of a hard cut to daytime. A lot of mods do something similar, but this mod takes a different approach to that.
The whole night-skipping sequence is animated locally on the client, so it doesn’t depend on the server or a perfect connection. The transition stays consistent and fluid for the player even with higher latency.

Version Control
This is a version control for Seamless Sleep as of 04/07/2026

Feel free to add me on Discord (gabrielfl4) or post an issue on GitHub to share your feedback on improvements :)
Update Roadmap to 3.0.0!
(ALL/Most to be released together)

Features
-
Smooth night → day transition
Replaces the abrupt time jump with a clean, blended animation when players sleep. -
Shared sleep animation
The transition is synchronized visually so all players see the same progression as the night is skipped. -
Sleep HUD polish
- Brightens and cleans up the default sleep HUD.
- Slightly tilts the camera while you’re in bed for a more relaxed feeling.
-
Configurable chat while sleeping
Adjust the opacity of both chat text and background specifically during sleep.
Useful for servers where players still talk while skipping the night. -
Cleaned-up messages
Hides the vanilla “passing the night” text and replaces it with a more subtle indicator.
Multiplayer timing & clock sync
If you notice that your sleep animation on a server is happening much later than other players, it’s usually a local clock issue on your machine.
To fix it: (I'll be working on it to improve this)
- Open the Date & Time settings in Windows.
- Enable automatic time synchronization or manually sync the system clock with an internet time server.
- Done!
Once your system time is corrected, your sleep animation should line up much more closely with everyone else’s.
Configuration
Seamless Sleep integrates with:
- Mod Menu – quick access to settings from the mods list.
All options are saved in seamless_sleep-*.toml, so advanced users can tweak things directly if they want.
License & usage
This project is currently marked as All Rights Reserved on Modrinth.
Even so, you are explicitly allowed to:
- Use Seamless Sleep in any modpack, public or private.
- Run it on any server or singleplayer world.
Please avoid reuploading the mod jar as your own or distributing modified copies separately – instead, link back to this Modrinth page.
Feedback & future plans
🐛 Found a bug or have a suggestion? Please open an issue or discussion on the Git repository linked on this page – feedback is very welcome.
The current focus is to bring Seamless Sleep to most versions on range of (1.20 - 1.21.11) in Fabric, Forge (when available) and Neoforge.
Lie down, let the night fade out smoothly, and wake up to a cleaner, less jarring morning transition.

### 2.6.2 -> Added Better Clouds compatibility!
Another pain update, thanks Neoforge for being highly complicated <3
### 2.6.1 -> **Oh yeah, replay compatibility... forgot about that...**
- "quick" and small fix on the math behind cloud movements to make them work with not only your computer time but also the replay timeline time (I'm going crazy, please help).
:)
_Thanks tylrcodes for the suggestion <3_
- Added cloud acceleration during sleep animation (client-side visual feature).
- Thats pretty much all the features on this update, but it was HUGE on code side...

Finally, I manage the 26.1 version. Had to rewrite a LOT of stuff.
Mainly, this new Mojang approach of dayTime called **clockManager** obligated me to literally revamp the whole core of my mod...
Idk if it was worth the pain, but it's out for you guys :)

_Basically, the animation was being broken by Minecraft... what?_
- Fixed premature wake-up during sleep animation (clear weather, rain, and thunderstorm).
- Players now stay sleeping until the animation actually finishes.
- Fixed **weather reset consistency after sleeping** (rain/thunder no longer fail due to premature cancel of sleep state).
- Reworked weather reset config: from
true/falseto **chance % (0-100)**. - Updated config UI (Fabric/NeoForge) and command support for percentage values.
Thanks to **kris19pr** for reporting this issue!
- Fixed a crash on dedicated (NeoForge) servers.
- Optional config/UI mods are now truly optional again (Fabric only requires Fabric API).
- Improved fallback config screen message visibility (when optional mods are not installed).
- Standardized config persistence to
.tomlwith NightConfig support and legacy compatibility.

This release focuses on polish, loader expansion, and compatibility improvements.
- Translation/localization received multiple adjustments.
- The project was ported to new loaders and now supports **Fabric, Forge, and NeoForge**.
- New configuration options were introduced, and the config setup was reorganized for a cleaner experience.
## Main highlights
- Added a controllable option (default: **ON**) that mirrors vanilla behavior by clearing weather after sleeping.
- Added a full math-layer refactor for sleep animation timing, improving compatibility with **ReplayMod** and **Flashback**.
