Hellscape – A Nether Revamp for Minecraft Java 26.2

Created by Zackattack4100 (MC name) / MoisturePack (PMC / Modrinth name)


MOD AVAILABLE ON MODRINTH

Hellscape is a complete overhaul of the Nether's default terrain generation, designed to make every journey feel larger, darker, and more atmospheric, while remaining unmistakably vanilla.

This datapack does not add any new blocks, items, mobs, or biomes. Instead, it completely redesigns how the existing Nether generates, making each biome feel unique, dangerous, and immersive without changing the game's core mechanics.


Features
  • Redesign of every vanilla Nether biome
  • Double the normal height of the nether
  • Dramatically improved terrain generation
  • A much darker, more oppressive atmosphere
  • Designed to make exploration feel exciting again
  • 100% survival friendly
  • Multiplayer compatible
  • Vanilla client compatible

A Bigger Nether

One of Hellscape's biggest changes is the Nether’s height.


The Nether height has been increased from 128 blocks to 256 blocks, creating larger landscapes and giving terrain much more room to breathe.

Even with the increased world height:
  • The Nether roof is still fully accessible.
  • Existing roof-based farms and transportation systems continue to work.
  • More vertical space simply means more impressive terrain below.

The result is a Nether that feels enormous without sacrificing familiar gameplay.


Vanilla-like

Everything you encounter already exists in vanilla Minecraft. No custom biomes. No new blocks. No new dimensions. No complicated mechanics to learn.


Compatibility

Hellscape was designed to be compatible with Artemis, Endeavor and Limbo!

How to update Hellscape after its been installed in your world

To update Hellscape in the future, all you have to do is open your world's datapacks folder, then delete the folder called
Hellscape and then drag the new Hellscape folder into the datapack folder, then you're done!

Feedback

I am just 1 person working on this project, so feedback is appreciated!

If you encounter any bugs or other glitches you believe are not intentional, please leave a comment here or message me on Discord/Planet Minecraft.


A Supported Project

This project is planned to be supported into future versions of Minecraft, making it reliable if you plan on using it on a server or intend to use the pack/mod long-term.

For the best experience, generate new Nether chunks after installing the datapack. Existing chunks will remain unchanged.

    Hello! Love the pack! I do have some critiques and feedback, but take as a grain of salt (I love your art direction so far)



    1. The warped forest is very blue, and although I like the color change effects in other biomes, the one in the warped forest feels to aggressive. I did like the way that there was kind of a whitish/ashy look when I was in the nether wastes biome looking at the warped trees. If you could add that or make the blue hue just a little less aggressive, I feel like it would be a very nice change



    2. For the mod version of this, could there be a config for the following?:

    -Disable/Enable welcome message

    -Disable/Enable colored lighting/fog for specific biomes



    -Disable/Enable mod achievements




    3. I do think it would be cool to have the nether roof not as flat, but kind of jagged with bedrock to make it feel uninviting/out of bounds-ish.



    4. Thank you for this creation! Even if you don't add any of these I will still play it with joy :D

    Well first i appreciate the genuine feedback and the kind words

    Secondly, i agree the warped forest is a bit too intense currently, and in the future i will be adjusting the intensity of the ambient light

    Third, there is no current way to disable the welcome message, BUT I will be working on a config that will allow Admins to disable the welcome message, and or the in-chat pop-up for achievements.

    As far as adding a config option for the colored fog/lights and completely disabling the achievements, im not sure that i will be able to do that. The only reason this pack is even available as a mod is because its simply a datapack packaged as a mod. Im not a mod developer so i would not know how to add that functionality.

    For the roof, i plan on keeping it flat to keep parity with vanilla MC as this pack was intended to be a vanilla-like upgrade to the nether, but its definitely something i will consider in the future, or maybe even package as a separate release.


    Thanks again for the feedback and kind words! it means a lot :)

    Hi there! First of all, I love this pack, it's exactly what I wanted from the Nether ever since the official world height increase of the Overworld <3

    Since you asked for feedback, I have noticed the biome specific distribution of lava springs. I adore how you cranked those up to the max for the Basalt Deltas, it feels very appropriate to be surrounded by lavafalls there. And within the standard Nether biome, they seem to still have their vanilla spread, which is also great.

    However, Warped and Crimson Forests and the Soulsand Valley don't seem to generate *any* exposed lava springs (while there are still plenty buried in the terrain). I'm unsure about how vanilla handles the spring frequency between biomes, but I would adore to have at least a few lava falls throughout the forest biomes and very rare ones in Soulsand Valleys. They always form such amazing flows with your expanded terrain generation and I really start to miss them outside of the main Nether and Basalt Deltas ^^'

    Additionally, maybe I've just gotten really unlucky or the new height is messing with their generation somehow but I have not seen any of those basalt pillars from the Soulsand Valleys. A return of those would also be greatly appreciated :)

    Final random thought without much direction: How about some sulfur? No idea in what biome to integrate it, maybe just the standard Nether with like small sulfur scars or whatever. I'm sure you could come up with something great! I just really feel like at least some sulfur belongs in the Nether and I cannot understand why Mojang restricted sulfur to the overworld ^^'

    That turned into quite a list of suggestions... but please be aware that I am still in awe of your work! And while it'd be awesome if you'd consider my feedback for a future update, I also fully understand if some stuff just doesn't fit your vision or if there are technical limitations. Keep up the great work! :D

    Hi! Firstly i just want to say thank you for the kind words! it means a lot to have people enjoy the things you create so i appreciate that!

    Secondly, no you havent just been unlucky haha, i did remove the lava springs from the soul sand valley, the crimson forest, and the warped forest as i thought it would help make the biomes more distinct but adding them back in would be fairly simple, and as a thank you for actually providing some feed back and genuinely putting some thought and care into what you wrote, ill release an update for Hellscape very soon that re-introduces the lava springs to the biomes i removed them from.

    I also did remove the basalt pillars but those can be re-added and was already something i was considering doing anyway!

    As far as sulfur goes, i could likely find a place for it in the Nether Wastes biome but that would be something i add in a future update.

    Thanks again for the kind words and helpful feedback! it means more to creators than you'd think!

    Hi there! You're very welcome but I also gotta thank you for making the Nether of my dreams (or rather nightmares?) :D



    And I do see your point, it does make the less lava-focused biomes more distinct from the rest. And as I said, it's completely valid to follow your own vision there. But I have to admit that do prefer the lava springs being an ever-present staple of the entire Nether. So thank you very much for considering adding them back in!



    I also think you don't have to sacrifice the distinct nature of the biomes in context of their lavafalls, since you're already handling it very well with the immense contrast between the frequency in the Nether Wastes and the Basalt Deltas. So just giving the remaining biomes also their own frequencies should still preserve the distinct feeling.



    Something along the lines of



    Basalt Deltas 150%

    Nether Wastes 100% (baseline frequency)

    Crimson Forest 75%

    Warped Forest 50%

    Soulsand Valley 25%



    feels about right. But I'm sure you'll handle this better than my spitballing here ^^'



    Also, very happy to hear about the potential return of the basalt pillars. The increased height will make these monoliths look even more imposing and I'm all here for it :D



    And finally, yes, the Nether Wastes would also be my biome of choice. Excited to see how you'd incorporate it if at all ^^



    Thank you so much for considering my (hopefully not too demanding sounding) feedback! I'm very happy to hear that my ramblings are leaving a positive mark on your creative process ^_^

    I'm loving it! I mean, I loved it before but these small updates really hit it home for me, great work! I honestly don't have any further notes thus far, so I guess just thanks again for providing the exact Nether experience I always wanted :D
