    @nesrak1 -- does this help you at all with your terrain question? Sorry, I forget exactly what you were looking for back then but I thought it might (possibly) be related.

    No, but I worked it out with suspension. I've known about the lods for a long time, but the batches were what I was trying to get.

    Could we get a another updated version of this 3D map now that the full v1.0 version of Subnautica is out and all of the final terrain touches have been made?

    release verison does not contain lod meshes (...\AssetBundles\lod?worldmeshes) and a third-party renderer from the original octrees was not found yet, so no.

    I still found these files, they were transferred into Unity-resources. There are a change, but nothing is noticeable. But I use the opportunity to publish 4K maps similar to those early (link to Imgur):

    In addition, I uploaded the same maps to Mega in PNG-format, all the original raw chunks in OBJ and the finished huge model of the world in PLY.
    The model can be opened in MeshLab; AO is assigned to the color of the vertices and the faces are painted in depth.

    Wow! Really lovely work.

    It shows the quality and complexity of the world - giving a great sense of relative scale too...

    It might also be worth combining with tanzanite's maps into a collection:

    I suppose between this excellent work you guys are doing and knowing the terrain format - we're only a couple hundred hours away from programming terrain editing tools?

    The more its white, the more its near the surface!

    @hhrhhr That Data is awesome, but do you have the original, after merging without modifications as well? Thanks in Advance
  • hhrhhrhhrhhr Russia Join Date: 2017-12-17 Member: 234462Members
    @Tom507 only source_obj.7z on Mega with 6016 individual objs. but you can merge them yourself layer by layer (floor by floor) with a simple command:
    copy *-XX-*.obj level-XX.obj
    
    where XX=0...24.

    hey, hhrhhr
    I am trying to make map from Subnautica Below Zero. I manage to extract those chunks with bits of map and load it into meshlab.
    Now I have about 9900 files with names like "Chunk_0_0_0-resources.assets-6282.obj", Chunk_0_0_1-resources.assets-6283.obj".
    I have found those files in \steamapps\common\SubnauticaZero\SubnauticaZero_Data\resources.assets and extracted meshes via AssetsBundleExtractor.

    I have merged them using your command "copy *-XX-*.obj level-XX.obj", now I have 24 OBJ files.
    But when I load them into meshlab, it shows me a cube, where all of meshes are inside of it = chaotic mess of meshes one clipping through another.
    This also happening even if I load non-merged OBJ files.
    If I load files separately, one by one, I can see bits of map.

    When I load your OBJ files of Subnautica map fom MEGA, they will nicely fit one beside another, creating a map.
    Can you please advice, what I need to do to achieve such result?
    thx.
  • hhrhhrhhrhhr Russia Join Date: 2017-12-17 Member: 234462Members
    all the "cubes" of the game world have local coordinates starting from zero. the size of these "cubes" - 32 game units. to combine into one large model, you need to add an offset to the local coordinates (chunk coordinate * 32)

    for example, the dot (10,20,30) in Chunk_1_2_3 will have global coordinates
    x = 10 + 1 * 32
    y = 20 + 2 * 32
    z = 30 + 3 * 32
    

    in order not to do this manually, you can use any script to recalculate the coordinates. I use a slightly fixed Lua script for the original game — https://gist.github.com/hhrhhr/0969a85afce034015b8cd02ac2544477 . This script, besides the offset of coordinates, at the same time fixes the coordinate system, since this system in Meshlab is different from the game one.

    Thx very much. As far as I studied those files, I think it does following:
    mass_convert.bat:
    will convert mesh files in *.dat format into OBJ by using mesh2obj.lua script. It will also recalculate coords like you said before.
    Then merge them.

    But that "mass_convert.bat", is expecting DAT files instead of OBJ I have. In AssetBundleExtractor, the only function, which creates DAT file is "Export raw" . However, this creates file with name like "unnamed asset-resources.assets-14252.dat", so I will lost all proper numbering like 0-0-1. Even if I try to modify bat file and change *.dat to *.obj, the "mesh2obj" fails with errors like:
    f:\lua53.exe: F:\\mesh2obj.lua:13: bad argument #2 to 'su' (string expected, got nil)
    stack traceback:
    [C]: in function 'string.unpack'
    F:\\mesh2obj.lua:13: in local 'uint32'
    F:\\mesh2obj.lua:38: in local 'convert'
    F:\\mesh2obj.lua:117: in main chunk
    [C]: in ?

    How I can get those *.dat fles, so I can convert it by your lua script? Or how to do it just with my OBJ files which I already have extracted?
    I have exported OBJ files in AssetBundleExtractor by selecting those files by its type (mesh) then going to Plugins->export to .obj
    thx

    mesh2obj.lua read "real" chunk name from *.dat and save OBJ with this name.
    -- fn = "unnamed asset-resources.assets-9267.dat"
        r = assert(io.open(fn, "rb"))

    I see now. Thx, it works.
    remove unnecessary (bottom at the level of three kilometers, side "walls"), clean (combine vertices, fix a bunch of irregular surfaces).
    Im completely new to meshlab. Worked with 3dsmax in the past, but meshlab is too different for me. How to combine all layers into one mesh, so I can do changes to entire model at once? Tried to goodle it but found nothing. Then I can remove side walls effectively, because now, I must select layer, then select vertices, then delete.

    I don't like video guides, but English is absolutely not my native language, so it will be easier for me to record a sequence of actions in the form of a video clip. Give me some time and i will do it...

    I can't seem to get AssetBundleExtractor to work so I've been using Asset Studio instead, which gives them the right name (unless that's an overall change made to the game?). What should I do then? (Sorry for the two years later response I just haven't seen anything else on it)

    map objects are now in a separate file: ...\steamapps\common\SubnauticaZero\SubnauticaZero_Data\StreamingAssets\aa\StandaloneWindows64\main-discrete_assets_worldmeshes_*.bundle

    Thanks for the response! I've been using that new file, but when I extract them as raw they have the correct chunk names as .dat files, which I don't think that .bat is equipped to handle since it isn't working (unless I'm missing a component here and it should be working fine anyway). So I'm wondering what to do now in this case, or if I'm missing something else (maybe the wrong lua installation idk) 8lnmisbpplh1.png
  • hhrhhrhhrhhr Russia Join Date: 2017-12-17 Member: 234462Members
    .bat and .lua scripts do not care about the name of the input file, it can be absolutely anything.
  • SpellingBee889SpellingBee889 Join Date: 2021-03-12 Member: 268233Members
    As some noticed, the previous map still had an entrance to the dungeon next to the "Aurora", which is not in the current version. Now more relevant game files were used.

    Hm. Must be an issue with something on my end then, probably with the lua scripts

    (This is what I have in the .bat, and when I run it nothing happens aside from the obj folder appearing in the work directory but staying empty)

    Hmm, I've been following along trying to piece together the Below Zero map, but the linked lua script appears to be bugging out on the asset call on line 59:
        assert(points == sz // 24, "\n\n" .. points .. " != " .. sz // 24 .. "\n\n")
    

    e.g. for Chunk-0-0-0.dat I'm getting the following output:
    PS D:\Tools\SubnauticaExtractor> C:\Tools\lua-5.3.6\lua53.exe .\mesh2obj.lua D:\Extraction\SubnauticaZero\worldmesh\RawMesh\Chunk-0-0-0.dat
    Chunk-0-0-0     17910 indices, 3178 points
    43 faces
    C:\Tools\lua-5.3.6\lua53.exe: .\mesh2obj.lua:59:
    
    3178 != 134919509
    
    
    stack traceback:
            [C]: in function 'assert'
            .\mesh2obj.lua:59: in local 'convert'
            .\mesh2obj.lua:117: in main chunk
            [C]: in ?
    

    I'm guessing either the file format has changed slightly - or the files got extracted slightly differently for some reason? :/ I didn't use AssetStudio because it doesn't recognize the new worldmesh.bundle file for me

    What I did notice is that the "faces" lengthalways appears to be "02 01 00 00" (258) in all the files I've tried - I'm wondering if that means the offsets have changed or if that's expected?

    If it's working for others on the latest version of the game files then I assume it's just an issue with corrupted files during the extraction process on my end.

    Yes, below Zero has slightly changed the mesh format. I rewrote the script with these changes (therefore, it should not work with the original Subnautica).

    https://gist.github.com/hhrhhr/ee63fbcd280f6110cc2f8184da857964

    In the same commentary there is a link to statically compiled Lua 5.4 for those who have difficulties getting Lua for Windows.

    Amazing!

    Although I think gist missing the mesh_utils_bz file?

    The mesh2obj_bz.lua file is trying to require that module but it doesn't seem to be present
