⋆ ˚｡⋆୨୧˚ Hi everyone! I'm more than glad to reveal you my not so new project, since it's a remake of my Undertale Map! ˚୨୧⋆｡˚ ⋆


➽ Given it's been almost 7 years since I started it (and finished it too), I've gained a lot of building experience over the last few years. So, after a quick look back, I realized that this map was, well... Hideous? Well, maybe I'm backlashing myself a bit, but from my current point of view, I'm not as proud as I used to be haha.

➽ My level of English has also progressed like a TON, since I've obviously found a LOT of syntax errors in the messages I've written in the map. I also noticed how ridiculously huge the rooms were for no reason at all. Like in Waterfall, the True Lab or in Judgment Hall... The Save Points weren't displaying the right text, there were animals and objects on the ground randomly in the map, my jokes were cringe (well after all it was 2019-2020, it's half forgivable...), I was improvising things like the transition between Snowdin and Waterfall or the CORE seen from Hotland, details were missing (the stalactites before the Hotland entrance, for example...).

➽ Anyway, I felt it was high time to give the map of this game I love a fresh look, rather than a poorly-improvised draft.

➽ In just under 2 months, I've had time to rebuild all the way to True Lab, and at the time of writing I've almost completed the first Level of Hotland (which also explains my inactivity on my Pokémon Map, for those who are wondering).I've managed (with my redstone and command skills lol) to get a few puzzles and mechanisms working, such as (without spoiling too much) the Snowdin tiles, the Monster Candy bowl and several interactive texts. I've also started working on a system that simulates the Fun Value events!

➽ In short, I'm much prouder of what I've managed to build. To avoid disproportions like the previous map, I chose to build in 2;1, a format I also adopted for my Pokémon map.

➽ I may also add the new Undertale Yellow zones in a different map, given the success this fangame has generated (it's well deserved!). But first things first, I'm going to complete the map of the main game.

➽In short, I hope this remake will appeal to more people and that my progress in building will be visible! (I've included a little before-and-after of some of the locations at the end of the description).

╰┈➤ About

➽ Version : Currently 1.21.4

➽ Shaders : BSL / Mellow / Complementary Unbound. If you have a low-end PC (kinda like mine...) I highly recommend Mellow ! :D

➽ Only a few mods ! I tried and will try my best to stay close to the vanilla aspect of Minecraft, while keeping it accessible to most of you in terms of performance. I added the bare minimum in terms of requirements: only 6 mods are mandatory at the moment :D

Everything will be provided in a Modrinth modpack to make everything easier ! Use the mod list below to see which ones are necessary, and those you can disable if you want to :

Mandatory Mods (Else the map will be either corrupted or broken) :
- BlocksYouNeed
- Some More Blocks
- Nature's Spirit/Regions Unexplored (These two are mostly for adding biomes, as I'm using a
  biome-based BGM mod)
- Flat Colored Blocks
- Biomes O' Plenty
- Colored Water
- Connected Glass
- Create (+ 3 addons = Deco Props / TFMG / Design 'n Decor)
- Framed Blocks
- Pale Garden Update for 1.21.1
- My Additions mod (very lightweight, don't worry)

+ Libraries used by some of these mods

Optional Mods (For a more immersive experience, QoL, and bonus things on the map) :
- Biome Beats
- Easy NPC
- Ambient Sounds
- Distant Horizons
- Performance mods such as Entity Culling, FerriteCore, ModernFix, etc.
- Just Zoom
- Sound Physics Remastered
- Motschen's Better Leaves (Resource Pack)
- Xaero's Mini/World Map

Recommended Shaders :
- Hysteria
- Insanity
- Mellow
- Solas
+ Gloomy brightness :]

I may or may not add some more in the future, if I find them relevant.
➽ Java Edition only, due to the usage of some mods.

Q&A

Q. : When will the next download update release?
A. : A question that's often asked, lol. This really isn't an easy answer though. Download updates might come out on a whim - this is most likely NOT gonna happen a lot. I'll probably follow a "once a region is done" schedule.

Q. : Can you port this map to Bedrock? / Is this map available for Bedrock?
A. : Sorry, but no. Due to the usage of some mods, this won't be possible.

Q. : Can I include your map on a modpack / server ?
A. : Of course ! Just make sure to credit me.

Update #8 - Tiny, tiny changelog : by daitsukii 02/21/2026 11:59:05 amFebruary 21 @ 4:59 pm UTC

Hey! I'm still not dead, lol. I mean, 2nd semester begun, I don't have all the time in the world to focus on Minecraft.

There isn't major changes in the build itself, but rather the mods and stuff.

  1. Version of the map downgraded to 1.21.1. It was so annoying to find alternatives to some of the mods I wanted, such as Flat Colored Blocks.
  2. New BGM mod : I opted for a biome-based music. Don't get me wrong, the previous one did the job but damn it was painful to set up everytime.
  3. Updated mod list! Check it out in the desc. I'm trying to keep it at more or less than 10 mandatory mods, especially for those of you who have potato PCs but still want to enjoy the map, lol.
  4. Currently STILL working on landscape. To be fair, I'm kinda struggling.
Here I go! It's not much, but I hope you're still tuned :]

Buh bye
