    Have you ever wished the Skylands of old were real? Have you ever wanted to use a glowstone portal for real? How about doing all of this in vanilla in a dimension carefully crafted for survival Minecraft, and even multiplayer? Ever wanted to survive in a new full dimension?

    Well today is your lucky day! The Skylands have been reborn, and they are better than ever! With the new dimension format, each Skylands will be unique to the seed of the world!


    How do I access this wonderful dimension, you ask? Simple! Build a standard 4 wide by 5 tall nether portal, except instead of obsidian, use glowstone, and instead of a flint and steel, use a bucket to place some water anywhere in the portal frame.



    Then simply hop on in! But watch your step on the arrival! (See gif below)



    The Skylands house incredible generation of a world with no bottom, deserts that could crumble any moment, and treacherous drops into the bottomless world. Most normal structures are included, including most vanilla biomes. All normal survival tools do also work, including beds which allow you to set your spawn, however see notes below for functionality regarding the bed. A nether portal will also not work.


    Special Effects:
    Certain mobs and a few blocks have special effects on them, inspired by the Aether mod. For instance, sand will give you a speed boost if you're walking on or above it! If you don't like these effects, there is a command to turn them off in the FAQ below.

    --- Warning! ---
    Due to how Mojang handles world generation, I have heard reports that you cannot delete dimension/world generation datapacks from your server after installing them, you CAN disable this datapack, and that will disable access to the dimension, but the datapack will probably have to stay in the server files to avoid any crashes or problems.



    This datapack also may impact world generation speeds, it's recommended to use a client/server with non-breaking optimization mods featured on clients such as fabric, if you plan to use this for a server or singleplayer, but this all depends on your specs, test in a fresh world before deciding to use!


    FAQ:




    How do I install this datapack?
    Simply download the file, and place it into the datapack folder of your world, no unzipping needed at all, or when creating a world, drag the downloaded file into the left pane to allow you to then add it to the world via the interactive list.


    How do I get rid of the special effects on mobs and blocks in the Skylands?

    If you don't wish to have those effects in play, simply use this command:

    /scoreboard players set skylandsreborn.effectsInSkylands skyrb.tracker 0


    What happens if I fall into the void?
    Since the Skylands are in the sky, falling off of them places you high above the overworld, should you take a misstep into the abyss. Hope you brought a bucket, or some water is nearby!


    Oh no! My portal broke!
    Fear not! Rebuilding the portal, and re-activating it with a water bucket should link it back up to the original portal, as when placing a destination portal for a newly created portal, it attempts to link to pre-created portals in the arriving dimension. If you want portals to not interfere with each other, a minimum distance of 16-17 blocks on the x and z axis is recommended to prevent cross linkage.


    I placed water in the portal and it didn't activate?
    There could be two reasons, you did it at an odd angle which my system couldn't track, or there may have been some other block inside the portal frame (stray flowing water if you just tried it and it didn't work, or any non-air block within the frame). Simply remove the water, wait for it to clear out, and try again at a less acute angle to the surface you are placing the bucket on. If it still doesn't work, make sure another portal isn't really close!


    I slept in a bed, but it's still night time?
    Unfortunately, due to how buggy minecraft (or snapshots) can be, currently sleeping in a bed in a different dimension lets you sleep, but doesn't set it to day for some reason. This bug is reported to mojang! We will see if they get around to it.

    One workaround is to travel to the overworld and sleep, then come back and set your spawn in the Skylands again, as the time of day and weather are currently fixed to the overworld time and weather.


    My portal won't ever link on my multiplayer server?
    If you've just installed the datapack, you will want to use /reload as well as restarting the server, since the new dimension can't be added while the server is running. If the problem persists, please feel free to let me know!


    I made two portals next to each other, and the second one didn't work/didn't light?
    Portals will not form if too close to another portal, try going a bit further away to get your second portal to light!

    This isn't working on my server!
    Your server owner may be using a modified server client host like paper which makes too many changes to vanilla that may break some datapacks/dimension packs, so there is not much I can do in that regard, ask your server owner if they have anything non-vanilla running the server!







    Can I use this in a youtube series/other creative project?

    Of course! As long as you don't claim credit for the development of the pack, or place extra restrictions on the distribution of the materials specific to my datapack.
    You may not reupload the pack or host a different download location for this pack without permission.


    You don't need to link to my page if it's cumbersome for you to do so, but an attribution link would be much appreciated!

    in 1.21.8 (paper server)

    when a player goes through the portal they get stuck

    but if they leave and join back then they are out of the glass panes in the portal frame

    So I'm not entirely sure what game version you are running, perhaps there is some kind of lag happening? It might be teleporting you constantly because of lag or something and it not resetting your portal cooldown to a number that won't TP you, but I can't tell because this is a very strange interface you have. Also you say that you leave and join, but the video just shows you pausing for a bit, which is why I think it might just be the server catching up?

    So I can't do anything for modified servers, that's up to the mods to have compatibility for vanilla commands, I can't spend a lot of time fixing for modded clients that might break vanilla commands for no reason.

    Is this datapack backwards compatible for 1.21.0? I get an warning message when loading the datapack that this is not the correct version, and I cannot go to the Sky Dimension after creating an Aether portal. The 1.20.X version of the datapack worked fine. Sorry about creating more work for you.

    I checked, the warning can be ignored, but back out of the portal and try again after a few moments, it seems this version has a loading time problem or something, it takes a bit for the dimension to be loaded.

    Edit 10/12/25: Please note the latest version may or may not work with 1.20 anymore, as some folder structure changes occurred in early 1.20 that made it too much to effectively backport.
