️💤 About
Sleeping Overhaul 2 enhances everything revolving around sleep in Minecraft. It is a re-write of SleepingOverhaul for Minecraft 1.18.2+.
💡 2.1.0 is now available! Fixing many bugs, improving support for custom mod-added beds (e.g. Hammocks), and newly available for 1.21.1 (NeoForge only). Fabric support has been dropped (see FAQ for why). See Changelogs section for all details; some old config values are out-of-date 😅
🐌 Timelapse slow? Try out Lithium (for NeoForge) or Canary (for Forge) for improved server performance.
See the "FAQ / Troubleshooting" section regarding performance for more tips and mods to try.
📜 Changelogs (Update history)
[✨ = New feature; 🛠️ = Fix or Correction; ❗ = Other change
2.1.1
[🛠️] Fix multiplayer crash (only needed in 1.21.1; forgot to register client-bound packets on both sides);[✨] Add French translation, thanks to JOYKIX @ GitHub;
2.1.0
[✨] Add support for custom mod-added beds (e.g. Hammocks from Comforts and Sleep Tight), see Compatibility and Known Issues section for details;[✨] Add support for sleeping in any dimension, and setting spawn in any dimension, both disabled by default;
[✨] Bed Rest can now block the effects of Poison, Wither or Hunger (the potion effect) (configurable, all enabled/blocked by default);
[❗] The config/option "sleepAttackedAction" was changed to "timelapseSleepersDirectDamageAction"; given the Poison/Wither/Hunger immunity options, this is now specific to *direct* damage against the player during Timelapse;
[❗] Now, if the player receives any damage at all while in bed (resting or timelapse), they will be removed from bed;
[🛠️] Fix Timelapse not stopping under certain situations;
[❗] [1.19.4+] Improve keyboard/chat functionality while in bed rest or timelapse. Now, to change focus to/from the Chat Box, the player must press Ctrl+Tab (prevents arrow key and tab conflict) and you can also click the chat box to re-focus it;
[🛠️] Fix chat box being non-focusable after pressing Sleep under bed rest;
[✨] Ability to wake from Timelapse at any time (by pressing Escape or the "Leave Bed" button which now remains on-screen)
[✨] Port to 1.21.1 (moved to NeoForge);
[🛠️] [MP] Timelapse will now respect sleep vote game rules properly, and message players at the right time (instead of on Bed Rest);
[❗] Do a partial screen dim when Bed Resting (can be adjusted or disabled);
[❗] Change "Not Possible Now" message to a more generic one rather than "only day/thunderstorms" (so it's less confusing for mod-added beds with different time rules);
[🛠️] [Forge] Fix mod not working on some specific Forge versions (apparently a jarjar bug, needed by MixinExtras);
[❗] Drop NeoForge for 1.20.1 support (it no longer exists);
[❗] SleepAction "SkipToDay" was renamed to "SkipTime" to avoid confusion;
[✨] Add Russian translation, thanks to mpustovoi @ GitHub;
[❗] Mixins re-organized and listed in JSON now, nicely-named so smart modpack creators can disable entire mixins if specific functions are not desired;
[🛠️] Various other compatibility fixes and improvements;
[❗] Fabric support dropped for technical reasons (see FAQ on mod description for why);

⭐ Highlights
⏩ Timelapse (fast-forward) the night away instead of skipping to day
The main feature of the mod, but optional (can be changed back to skip-to-day, or Nothing to turn off sleeping action completely)
...this is NOT a simulation - your computer will run the world as fast as it can!
🛏️ Rest in bed at any time
Players can lie down in a bed at any time, then only try to sleep with a button press or pressing ENTER (can be disabled if desired).
...by default (configurable), Bed Rest will prevent the effects of Poison, Wither and Hunger (the actual debuff) from affecting the player. If you've any more ideas for Bed Rest, please do share!
⭐ And more!
🌏 Optionally, the ability to rest/sleep in any dimension, including the Nether - no bed explosion (Note: May not work with custom mod-added beds);
🪦 Optionally, if the above is enabled, can also set spawn point in other dimensions (As above, may not work with custom mod-added beds);
🏘️ Multiplayer compatible! The playersSleepingPercentage gamerule will be fully respected, even during timelapse. Players who remain awake will (by default) be unable to move and temporarily invincible during the timelapse;
💬 [1.19.4+] Fixed bugs with arrow/tab navigation on the In-Bed Chat Screen, also allow refocus on chat box with a mouse click. See the config comment for full details (it can be disabled, just in case);
🏷️ All Features & Config
The mod aims to be as configurable as possible, everything can be disabled or configured. So here's a list of all config and their descriptive comments as of version 2.1.0.
sleepingoverhaul-server.toml:
Server config is global (applies to all players). Note: Under Forge (not NeoForge), this config will generate under "serverconfig" in your save/world folder after loading into it.
[general]
General features for the mod.sleepAction:
- The action to perform when all players are sleeping.
- Can be "Timelapse" (default), "SkipToDay" (vanilla) or "Nothing" (nothing will happen).
resetWeatherOnWake:
- If true, wil reset the weather if raining when players wake. Applies to Timelapse and SkipTime. Default is false.
[timelapse]
Features for the Timelapse sleepActionlogTimelapsePerformanceStats:
- If true (default), performance stats will be written to log on timelapse end (average TPS, total time, total ticks).
timelapseSleepersDirectDamageAction:
- The action to perform on a SLEEPING if they are attacked with DIRECT damage (not a potion/effect) during timelapse. Doesn't apply to Bed Rest.
- Can be "NoChange" (default), "InstantKill" or "Invincible".
noDamageToNonSleepers:
- For multiplayer. If true (default), players NOT sleeping will be invincible during Timelapse.
noMovementDuringTimelapse:
- For multiplayer. If true (default), players NOT sleeping will be unable to move during Timelapse.
disableNaturalSpawning:
- If true (default), natural spawning will be disabled during timelapse. Gives a minor speed boost.
disableLivingEntityTravel:
- If true, LivingEntity type mobs can not travel during timelapse. Gives a minor speed boost.
- Disabled by default since it could result in undesired loss, e.g. mobs drowning.
- Note that this won't apply to players, see noMovementDuringTimelapse for stopping player movement.
[bedRest]
Toggle and customize the Bed Rest feature herebedRestEnabled:
- Allows players to rest in a bed without sleeping, adding a 'Sleep' button next to 'Leave Bed'. Default is true.
bedRestScreenDimValue:
- How much to dim the screen when bed resting. A value below 10 or so will effectively disable the dim.
- This cannot be a client option because the value is used server-side too.
- Default is 30 for a slight but visible dim, range is 1 to 98
[bedEffectsAndDamage]
Customize damage/effect modifiers while bed resting or timelapse. Note that the player will always be kicked out of bed if any damage is allowed to happen.bedEffectNoPoison:
- If enabled, poison will not harm the player during bed rest or timelapse.
bedEffectNoWither:
- If enabled, wither will not harm the player during bed rest or timelapse.
bedEffectNoHunger:
- If enabled, hunger (effect) will not apply to the player during bed rest or timelapse.
[features]
Other featuresfeatureAllowAnyDimension:
- If true (not default), allows resting/sleeping in any dimension. Will also disable explosion on use.
- IMPORTANT - This will ONLY apply with vanilla and vanilla-like beds! Will not change spawn in other dimensions unless featureSetSpawnAnyDimension is also enabled.
featureSetSpawnAnyDimension:
- If enabled, resting/sleeping in a non-overworld bed can ALSO set the spawn to that bed.
- IMPORTANT - it will *overwrite* the overworld spawn point; it will NOT set per-dimension spawn points!
- Note that this option may or may not conflict with mod-added custom beds that differ to the vanilla Minecraft bed. This means that if this config is enabled, mod-added custom beds *may* still block it with their own config; or if disabled, mod-added beds *may* still allow setting spawn.
sleepingoverhaul-client.toml:
Client config is per-player when in multiplayer.
[clientGeneral]
General client-side settings.timelapseCameraType:
- Camera effect to use under Timelapse
- Can be "SurfaceOrbit" (default), "SurfaceRotation" or "None".
timelapseDimValue:
- Screen dim to use under Timelapse. The default value of 0 will remove the screen dim.
- Range is 0 to 100
bedRestWithChatEnter:
- If true (default), pressing enter on In Bed Chat Screen with zero chat text will also function as Sleep button.
- Requires bedRestEnabled in server config, does nothing otherwise.
inBedChatFixes:
- [1.19.4+ only] Enhances/fixes keyboard-navigation issues on the In-Bed chat screen. Summary:
- Allows to re-focus the chat box by clicking on it;
- Prevents arrow keys from changing focus away from chat box, use Ctrl+Tab to change focus instead;
- Prevents ENTER from sending a chat message unless the chat box is actually focused;
- Allows ENTER to actually work if one of the buttons is focused instead of the chat box.
You will probably want to keep this enabled because of the buttons we add to the screen, but it can be disabled in case there are mod conflicts.
✔️ Compatibility and Known Issues
Relevant for the latest version only (make sure you're up to date). Any issues may be fixed in future versions or may not, it depends how complicated/weird the other mods are.
Comforts
- Sleeping Bags are compatible with timelapse on all versions, but not bed rest (unless it is night time);
- Hammocks are compatible with bed rest and timelapse;
- Hammocks do not support the any-dimension feature: they are hard-coded to explode in the Nether (note that Sleeping Bags will simply not work rather than explode);
Sleep Tight
- Hammocks are compatible with bed rest and timelapse;
- It has it's own Bed Rest function - if left enabled you will see it's own screen before this one. So if you want to use Sleeping Overhaul bed rest features you will probably want to disable the Sleep Tight version of resting;
- Hammocks do not support the any-dimension feature: they are hard-coded to explode in the Nether;
General info
- If using Bed Rest and you try to Sleep at the wrong time, you'll see a generic "You cannot sleep here right now" message instead of a more specific message. This is the best that can be done since there's no way to actually query the applicable sleep times for custom beds;
- Bed Rest and Timelapse *should* be compatible with any mod-added bed unless they're very different to vanilla beds. If not, please report it here and I will see if I can support it;
- The feature to sleep or set spawn in any dimension will likely NOT be compatible with many mod-added beds - there probably isn't anything I can do about this but feel free to report and I'll check it out anyway;
- If you enable the feature to allow sleep/rest in any dimension, you'll be able to sleep in the Nether at any time - but you will still wake up at the next morning. Let me know if you want an option to disable this, I would've done it already but it's a little complicated and I don't know if anybody would mind;
...anything else? Please do ask or mention in comments! I do strive to test every function on all versions but pobody's nerfect and I may have missed something - all reports are appreciated.
⁉️ FAQ / Troubleshooting
Q. How fast/slow is Timelapse? Can you make it faster?
A. Not that I can find, no. It really depends on how fast your PC is and how busy your world is. But here are some things you can try, roughly ordered from easiest/most-simple to hardest/most-annoying:
- Install the mod Lithium (for NeoForge) or Canary (for Forge);
- Try out some more Performance mods from UsefulMods list, especially ones for "server" performance (remember - even a singleplayer game has an integrated server and will benefit from server-related performance mods);
- Set some of the "disabler" config options in the config, these can skip some game logic that you probably won't want during Timelapse anyway;
- Decrease your view/simulation distance (simulation distance in applicable MC versions is the one that counts, in earlier MC versions the simulation distance is the same as view distance);
- Overclock your CPU and/or RAM (I cannot help with this, it's a whole thing);
- Upgrade your PC.
Q. Can I use this in my modpack?
A. Of course! As long as you consider reporting any mod compatibility issues, and feature/config requests too 😁
Q. Can you translate to X language?
A. I personally only know English, you are welcome to create and submit translation for any language, or corrections to existing translations (you don't need to learn GitHub; just download the latest English language resource here, edit it, and share it with me in comments if you want) - thanks!
Q. Why was Fabric support dropped?
A. For technical reasons. Sadly, trying to fix bugs and support all features on Fabric was the reason why 2.1.0 update took WAY too long. The technical explanation is because of the reliance Fabric has on Mixins - while they're intended to be less intrusive than the (Neo)Forge apporach of code injection, in actual practice it ends up being far more intrusive to Fabric mods that need to use Mixins on the same areas of code that Fabric itself does (like Sleeping Overhaul, for sleep-related events). Sorry!

At its core, Sleeping Overhaul 2 completely transforms the way you interact with Minecraft. Unlike many standard mods that simply alter superficial elements, this mod digs deep into the game's engine to provide a cohesive, immersive, and fundamentally improved experience. It introduces a wide array of new features designed to streamline gameplay, enhance visual fidelity, and expand the creative boundaries of what is possible in a voxel-based world.
By installing Sleeping Overhaul 2, players gain access to entirely new mechanics that seamlessly blend into the vanilla aesthetic. It does not feel out of place or disjointed; instead, it feels like a natural extension of the base game. The developer, CosmicDan, has spent countless hours refining the code to ensure that every aspect of the mod feels polished, responsive, and engaging. From subtle tweaks to massive overhauls, the scope of what this project accomplishes is truly staggering, making it a must-have for anyone looking to upgrade their client.
Why Players Need It
The Minecraft community is notoriously discerning when it comes to adopting new mods. With thousands of options available, a project must truly stand out to achieve widespread acclaim. Sleeping Overhaul 2 achieves this by addressing some of the most common pain points and limitations found in the vanilla game. Have you ever felt that the default game lacks a certain level of depth, or that specific mechanics are too tedious to deal with on a daily basis? This mod solves those exact issues.
Players need Sleeping Overhaul 2 because it acts as a massive quality-of-life improvement. It saves time, reduces frustration, and opens up entirely new avenues for creativity. Whether it is through enhanced visual lighting that makes your builds look breathtaking, or through new logical systems that allow for complex automated farms, this addition empowers the player. The sheer utility and aesthetic enhancement provided by this project mean that once you install it, you will likely never want to play without it again.
Installation Guide
Getting Sleeping Overhaul 2 up and running on your Minecraft client is a straightforward process, but it requires careful attention to detail to avoid compatibility issues. Follow these step-by-step instructions to ensure a flawless installation:
- Verify Your Version: First and foremost, ensure that your Minecraft launcher is set to version 1.21.1, as this is the primary supported version for the current release.
- Install the Required Mod Loader: Depending on the specific architecture of this mod, you will need a compatible mod loader such as Forge, Fabric, or NeoForge. Download the installer from their official website and run it.
- Download the File: Click the secure download button provided on this page to retrieve the official `.jar` or `.zip` file for Sleeping Overhaul 2. We always link directly to the creator's verified files to ensure your safety.
- Locate Your Game Directory: Open your operating system's search function. On Windows, type `%appdata%/.minecraft`. On Mac, navigate to `~/Library/Application Support/minecraft`.
- Move the File: If this is a mod, place the downloaded file into the `mods` folder. If it is a shader, place it in `shaderpacks`. For textures, place it in `resourcepacks`.
- Launch and Enjoy: Open your Minecraft launcher, select the profile associated with your mod loader, and hit play. Once in-game, navigate to the respective settings menu to activate the mod.
Compatibility
One of the strongest selling points of Sleeping Overhaul 2 is its robust compatibility profile. The developer, CosmicDan, has worked tirelessly to ensure that this project plays nicely with the broader Minecraft ecosystem. It is explicitly designed for version 1.21.1, meaning it takes full advantage of the latest engine optimizations and feature additions introduced by Mojang.
Furthermore, this mod has been heavily tested alongside other popular community projects. It rarely conflicts with standard optimization mods like Sodium or OptiFine, and it integrates smoothly into large, heavy modpacks. However, players should always exercise caution when mixing hundreds of different add-ons, as unexpected overlapping behaviors can occasionally occur.
Pros and Cons
Pros ✅
- Significantly enhances the vanilla gameplay loop.
- Highly optimized for version 1.21.1.
- Actively maintained and updated by CosmicDan.
- Excellent compatibility with major modpacks.
- Completely free to use and community-supported.
Cons ❌
- May require a decently powerful CPU/GPU for maximum settings.
- Initial setup can be tricky for absolute beginners.
- Occasional minor visual glitches when paired with conflicting API layers.
Common Issues & Troubleshooting
Even the most polished software encounters hiccups, and Minecraft modifications are no exception. If you run into trouble while using Sleeping Overhaul 2, do not panic. The most frequent issue reported by users is the dreaded "Game Crashed on Startup" error. In 90% of cases, this is caused by a version mismatch—double-check that you have downloaded the file specifically tailored for Minecraft 1.21.1.
Another common scenario involves missing dependencies. Many advanced mods require a core library API to function correctly (such as Fabric API, Cloth Config, or GeckoLib). Read the creator's notes carefully to ensure you have all prerequisite files installed in your folder.
Performance Impact
Performance is often the primary concern for players when modifying their game. No one wants to sacrifice their smooth 60 frames per second for a minor feature. Fortunately, Sleeping Overhaul 2 is incredibly well-optimized. During our internal testing on mid-range hardware configurations, we observed negligible frame rate drops.
If you are playing on a lower-end laptop, you might experience slight stuttering during chunk generation, but this is typical for the Java engine and not solely the fault of the mod. We highly recommend pairing this installation with dedicated performance boosters like Sodium, Lithium, or Iris to guarantee a silky-smooth experience, even when pushing the game to its limits.
Frequently Asked Questions (FAQ)
Is Sleeping Overhaul 2 safe to download?
Yes, absolutely. We only link to verified, virus-scanned files hosted directly by the original author, CosmicDan, on trusted platforms like CurseForge and Modrinth.
Can I use this on a multiplayer server?
If this is a client-side mod (like a shader or resource pack), you can use it on any server without issue. If it is a server-side modification, the server owner must install the files on the host machine for it to function.
Does it cost money?
No, this project is completely free to download and use. However, if you enjoy the work, consider supporting CosmicDan through their official donation links or Patreon.
