I build a lot from schematics and kept doing the same thing: open the world, load the schematic in Litematica, check the material list, do the maths for shulker boxes. So I wrote a small desktop app for the part that doesn't need the game open.

What it does:

- Imports .litematic, .schem (Sponge), .schematic (WorldEdit) and .nbt structure files into a local library with thumbnails.

- 3D viewer with a layer slider, so you can go up one layer at a time.

- Material list as an exact count, in stacks and in shulker boxes (16-stackables and unstackables are handled), exportable to CSV.

- Basic block editing: swap a block for a similar one (e.g. oak to spruce across the whole build), with undo history.

- Textures come from the Minecraft jar you already have installed. Nothing from Mojang is bundled.

You can try it in the browser without installing anything:

https://www.aserrano.dev/demo/schematic-lab

Get it on the Microsoft Store (Windows 10/11, 64-bit, free):

https://apps.microsoft.com/detail/9P3WWV65DTR6

Or as a plain installer from GitHub:

https://github.com/AngelSerranoD/schematic-lab/releases/latest

Things to know: it's a personal project and Windows only. The GitHub installer isn't code-signed, so SmartScreen will warn you there ("More info" → "Run anyway"); the Store version doesn't have that problem. It works offline and sends no data. It's not affiliated with Litematica, Mojang or Microsoft.

Feedback welcome, especially schematics that fail to load or material counts that look wrong.

Okay, so I started a new Bedrock world, made a base inside a village, and then made an iron farm 150 blocks away from the village. Iron far works perfectly. However, when I am inside my base, which is 158 blocks away from the farthest edge of the farm, it doesn't run.

My simulation distance is set to 12 chunks. Using chunkbase seed map to visualize the chunk margins, I should be 10 chunks away.

So, my questions are:

1. Do iron golem farms work on simulation distance, or mob spawning distance, and are those two things different?

2. What is the farthest I can actually be from the iron farm and still have it run?

3. Is there some other nonsense I'm just missing?

Ultimately I'd like to have a centralized AFK spot to build a hub and spoke type setup, but I need to figure out where I can even be first.

Never made a slime farm, needed slime blocks on the cobblemon server but its just not working, followed a yt tutorial but it just isnt working, I tried lighting up the caves below the farm too idk if it being cobblemon messes with things but if I made any obvious mistakes lmk

What is a good iron farm that works in 26.2

Hi!

I'm 400 days into my Hardcore world and finally starting my first megaproject (no main base yet!). I'm building the Evangelion 3.0 Central Dogma crater / NERV HQ complex.

The inner crater footprint is roughly ~300x300 blocks (from the inside of the crater outline).

A few technical questions for the experts:

1. What World Eater or trenching machine design would you recommend for a ~300-block span in modern Java (1.26.2+)? Looking for something reliable with liquid pushers/sweepers, as there's water inside the perimeter.
2. What's the safest way to keep the entire machine loaded while running in Hardcore? Is cranking my Simulation Distance to 32 enough on singleplayer, or should I be running Portal Chunk Loaders on the docking stations?
3. What is the safest Simulation/Render distance margin so no part of the machine hits unloaded chunks and blows up?

So I’m sure I’m going to get a lot of no’s to this request. I turned on the minecart improvements on my server with a max speed of 32 or 64 on my server, and am finding that the simpler standard minecart loader/unloader designs can be very sensitive to minecart speed. The carts like to phase through solid blocks at the end of sloped rails, or depart unloaders before the redstone can trigger to hold it, etc.

Was curious if anyone has experimented with designs that work more reliably at “any” speed? Most of my ideas to “reset” speed to make the standard designs more reliable involve waterlogging rails to force carts to slow down, or running into walls+dropping to stop horizontal momentum, etc., but this ends up being really bulky in practice.

So been playing on a new hardcore world day almost 200 days. I have a iron farm 4 villager 100% efficiency by Nico is Lost, a witch farm by C5, hoglin farm made by me. And i been looking for other farms like a slime farm bamboo and, string option to farm for a shulker farm and maybe other things in the future, and a tree farm suggestion, bartending farm. And other farms what you think i need to have in the world???

After updating my world from 1.21.11 to 26.3 my mob switch stopped working.

Screenshot 1 and 2: Spawn chunks (I kept the old size of spawn chunks), I have 72 zombie villagers (traded) with only 1 who has an item (71 counting entities towards the mob cap), they are located within the first lazy chunk of the spawn chunks.

Screenshot 3: Somewhere random really high up, Carpet mod shows that I have no hostile mobs in the mob cap, mobs spawn at night.

Did they change anything with spawn chunks that I'm not aware of?

I'm not too well-versed in them so I wanted to know

Is there a max speed at which railguns can shoot arrows AKA is there a max speed arrows can move at and if so what is it

I found this design for my mob farm flushing clock but its not working its giving me symmetric timings and i don't know what I'm doing wrong , i need 4,5 seconds on and 12 seconds off

If there is a better design that would help too

Is there a new design for a enderpearl stasis teleporter?

Last time I played was 1.21 and I build the one with the cats.

Does it still work and if it doesn't is there another way to build it ideally the same functionality with relogging

ITS RIGHT THERE BRO

I was wondering what you guys think. I would define rare as hard to find (low chance to find it) and not just scarce like the ender dragon egg.

Right now my collection would be:

All the mob heads

The 4 goat horns

Deepslate Coal, Deepslate emerald

Normal stone diamond

Trident Mace

Tall grass

Blue axolotl

All discs

Am i missing something? What about illegal items? Are there any on 26.3? Maybe bedrock and end portal frame?

I was messing around in my Son's creative server when I accidentally immortalize this Golem and now he can't be killed.

Made this silly design after the post asking for a pumpkin farm that detects pumpkins on bedrock.

I want to be able to push a button, something triggers, then exactly 3 minutes later, something else triggers.

I am struggling to figure out the hopper clock logic for that. IDK. Plz help.

The blaze spawners are close enough to have both triggered.

For wither skeletons, I have two different touching crossroads. To my understanding, it would be better if they were slightly separated, correct? But it is still 4 crossroads in really close proximity, even if they overlap.

Am I wrong for saying this is a really good fortress?
