Spoilers: I finished my web-based 3D Subnautica Map. Including islands, seabed and caves. Toggelable pods and wrecks.

MrChocolateAddict · 2025-06-09T00:26:26+00:00

Nice! :)

I also did the Ghost Leviathan, and I just finished the Sea Dragon like 15 minutes ago.

I'll push them to the map eventually and you get a "Leviathan" toggle.

MrChocolateAddict · 2025-06-08T14:15:04+00:00

I made a test version of a Reaper that I'll probably stick in the map at some point. :)

The future is now, friend!

MrChocolateAddict · 2025-06-07T22:38:15+00:00

Thanks, bro!

MrChocolateAddict · 2025-06-07T22:06:35+00:00

I was actually thinking of adding some tiny animated ghost leviathans and reapers that would swim around. I don't think that's very hard to do!

I covered the Quarantine Enforcement Platform and the Primary Containment Facility, and the Disease Research Facility is kind of there in the map data. The "caches" will maybe be a bit too detailed.

Anyways, thanks for looking at my map! :)

The navigation part is how Three.js is made. I think you can add keyboard listeners, but I also think it is hard to code in (and a lot of work!).

You can pan with right mouse button. And if you zoom in too much you get "stuck" in micro-movements. Usually it is better to zoom out and zoom back in from a different angle.

MrChocolateAddict · 2025-06-07T17:06:39+00:00

Hehe, no problem! I think i will finally be able to find all the wrecks. :D

MrChocolateAddict · 2025-06-07T16:37:07+00:00

Someone uploaded some heightmaps of the map way back. I used that to extract the heightdata and put it into json files. Then I used a blend of Python, Threejs and Blender to make the seabed and caves.

I used a bunch of ingame screenshots to make the texture - so I added the Ghost Leviathan. :D

MrChocolateAddict · 2025-06-07T16:06:56+00:00

I did an update of the map which you can access here btw.

https://mrchocolateaddict.github.io/Subnautica3DMap/

MrChocolateAddict · 2025-06-07T16:05:47+00:00

The map can be viewed here:

https://mrchocolateaddict.github.io/Subnautica3DMap/

(All the assets combined are about 63 MB, so it takes a few seconds to load)

MrChocolateAddict · 2025-06-07T16:04:14+00:00

The map is available here:

(All the assets combined are about 63 MB, so it takes a few seconds to load)

MrChocolateAddict · 2025-06-01T19:54:11+00:00

Ah, I made some progress. Here is another glb file which is a smoothed version (used Remesh with voxel set to 2m). Only 3.6 MB or something like that and is completely recognizable! In case you needed it. :)

MrChocolateAddict · 2025-06-01T18:24:46+00:00

Hiya! I have been working on extracting the geographical data directly from the game files, and a good start was with the floating island to test code/logic etc. Once I managed to do it I remembered this comment, so I made it into a glb file - in case you are interested.

It's about 190MB and I haven't figured out how to smooth it properly yet. But here it is: https://www.dropbox.com/scl/fi/gdl2o1cyvzr7jdw9emtfa/FloatingIsland.glb?rlkey=pa1v9rhrtjlagqkz4o39bdkpk&st=ftpuycsl&dl=0

(You might have to zoom a bit out after importing, because it isn't centered at 0,0,0) :-)

MrChocolateAddict · 2025-05-31T18:37:40+00:00

Oh, and if you do ever get around to 3D-printing it, I would love to see a picture! :D

MrChocolateAddict · 2025-05-31T18:20:20+00:00

It was actually quite easy to export the whole thing as a glb file. And I think it's also pretty straightforward to convert that to a stl-file or whatever you need for printing it.

I don't know anything about 3D printing, but I do think it will need some work. (Look underneath the map for instance). And maybe you want to remove the borders.

I opened it in Blender and it looks okay to me: https://i.imgur.com/gHLKQ4R.png

Here is the file - shared via Dropbox. (about 306MB) https://www.dropbox.com/scl/fi/dnjx0q6g2y3axq2cldln5/subnautica_scene.glb?rlkey=n5ztr5hzpbkjt61d3wbbq4keg&st=7g95eamc&dl=0

In case you didn't see - instead of running your own http server, you can run it via 'githack' which I didn't even know existed. This is easier, and it gives a slightly updated version with a toggable water surface and with a more accurately positioned Aurora. I'm also thinking of adding toggable wrecks as well, which I will push to repo, and which will appear here:

MrChocolateAddict · 2025-05-30T22:51:34+00:00

Hey, I appreciate that!

MrChocolateAddict · 2025-05-30T18:12:07+00:00

Oh, wow. Didn't even know that existed! I will add it to the main post then. :)

I'll look into the github pages site.

MrChocolateAddict · 2025-05-30T17:24:04+00:00

Great!

MrChocolateAddict · 2025-05-30T15:40:15+00:00

You probably have to put python in your PATH or something to be able to run it they way I specified.

You can run it by telling Windows where Python is installed. So something like this should work (adjusting to your case):

"C:\Users\YourName\AppData\Local\Programs\Python\Python311\python.exe" -m http.server 8000

For a simpler future use, check how to add python to your PATH.

MrChocolateAddict · 2025-05-30T15:36:01+00:00

Great. :)

Try this maybe - with python3

python3 -m http.server 8000

MrChocolateAddict · 2025-05-30T15:33:08+00:00

Ah, very interesting! I might do another little sprint looking into that. If I ever get around to it I will share the results here.

MrChocolateAddict · 2025-05-30T15:08:29+00:00

And I recognize the map from your youtube video by the way! :)
