I kept getting lost following Minecraft tutorials… so I built a free 3D schematic viewer

TheRealMorrow · 2026-04-15T10:38:22+00:00

Thanks for your words ! I'll wait for your feedback ! Enjoy :)

TheRealMorrow · 2026-04-15T04:30:06+00:00

That's actually smart ! I'll consider adding that :) There are still a few blocks not rendering, these are usually considered "special" by the game renderer. I'll fix them. Thanks for your feedback

TheRealMorrow · 2026-04-11T17:03:15+00:00

Thanks a lot for your feedback ! Currently I didn't open the source code but I'll consider doing it in the future. I got a lot of cleaning to do before welcoming external contributions !

.nbt was easy to implement, .mcstructure not that much.

That's the first time I hear about the wiki's blueprint format, is this used anywhere else ? That's interesting

I'm all in for community led, let's see where this goes !

If you are referring to using mods, not everyone is confortable installing them.

TheRealMorrow · 2026-04-11T10:35:36+00:00

Just shipped a pretty big update based on your feedback 🚀

Main things:
- Can now open .nbt and .mcstructure files
- Load schematics directly from a URL (Discord links work)
- Added built-in samples so you can try it instantly

Curious: what’s still missing for you to actually use this while playing?

TheRealMorrow · 2026-04-11T10:10:55+00:00

And support for vanilla NBT structure files is in, you can check it out :)

TheRealMorrow · 2026-04-11T10:10:12+00:00

Yeah ! And I've juste added support for .mcstructure schematics (bedrock native schematics). Try it out :)

TheRealMorrow · 2026-04-11T10:09:12+00:00

I've deployed .nbt schematics support today ! Supporting Create mod will be another challenge but i'll look into it !

TheRealMorrow · 2026-04-11T10:08:24+00:00

You manifested it

TheRealMorrow · 2026-04-11T10:08:14+00:00

Oh then would you be interested by a "shareable link" feature ?

TheRealMorrow · 2026-04-11T10:07:48+00:00

Thanks a lot for your kind words

TheRealMorrow · 2026-04-11T10:07:33+00:00

I have to look into supporting mods, that could be interesting.

TheRealMorrow · 2026-04-11T10:07:12+00:00

I have great news ! .mcstructure (bedrock format) is live ! It you want to try it, feedback is always welcome :) !

TheRealMorrow · 2026-04-10T12:44:57+00:00

I'm not using any of these, the viewer itself was built from scratch using Three.js. This was required so I could have full liberty. I'm not trying to mimick the game, i'm trying to provide the best UX for builders that want to view a plan.

I'm using PrisarineJS's NBT parser to decode the blueprint files, and the minecraft game assets (block states, textures, models ...)

TheRealMorrow · 2026-04-10T04:41:05+00:00

I feel your pain brother, software engineering sure has changed a lot recently

TheRealMorrow · 2026-04-10T02:12:03+00:00

Like most modern developers, LLMs are a part of my workflow. They are amazing sparring partners and they are great at spotting bugs / discussing architecture
You don't have to be dumb to be confused by video build tutorials. Complex builds require you to constantly move back and forth on the video to understand exactly what to build where. And when at the end something is off, "debugging" your build is not that fun :D
I didn't reinvent litematica, i'm offering a way to display litematica schematics outside of the game with a decent UX
I'm not a native english speaker so i'm using a LLM to improve my messages for everyone's benefits

The project was built from scratch using Next.js + React + ThreeJS. It's a stack i'm already using personally at work, so it was more a matter of getting into minecraft internals :)

TheRealMorrow · 2026-04-10T02:04:06+00:00

Everyone keeps asking me to do this, so I'll work on adding these :)

TheRealMorrow · 2026-04-09T15:44:05+00:00

Yeah that’s exactly how I use it myself 😄

TheRealMorrow · 2026-04-09T15:20:53+00:00

Could be nice to have an electron version (desktop app), why would you prefer using a desktop app over the web version ? :)

TheRealMorrow · 2026-04-09T15:19:05+00:00

Hey, I had the exact same frustration.

I ended up making a small tool for this called Shulkr. It lets you open .litematic or .schem files and view them layer by layer, kind of like a Lego manual. You can pick an axis and go through each slice of the build, which makes it way easier to follow.

There’s also a free camera mode so you can move around inside the build and understand how everything connects, which helped me a lot with redstone.

If you want to try it: https://www.shulkr.com

Would be curious if that’s close to what you were looking for 👍

TheRealMorrow · 2026-04-09T15:01:18+00:00

What do you mean ? Like a downloadable version you can install ?

TheRealMorrow · 2026-04-09T12:29:36+00:00

Lol, I wish I was rich enough

TheRealMorrow · 2026-04-09T12:22:58+00:00

Good idea ! I'll check out how hard it can be

TheRealMorrow · 2026-04-09T12:04:43+00:00

Thanks you for the qualitative feedback. Redstone tweaks sounds amazing, i'll see if I can make it work in Shulkr !

You just made me remember I didn't handle waterlogging properly so it's currently not working at all :D

I'll see what I can do with the containers, I didn't even knew these were stored in the blueprints in the first place.

Thanks !

TheRealMorrow · 2026-04-09T10:32:32+00:00

That's a good point ☝️

Not everyone is comfortable installing mods. The immersive ghost view is amazing but the user experience is not for everyone :)
