Loss of Textures When Converting 3D Tiles to SLPK Using Tile Converter

[MoCongxin]

I was attempting to convert 3D tiles to SLPK files using the Tile Converter in a Docker container on Windows, but I encountered a problem where all the textures were missing. Additionally, running the same command occasionally fails, with a success rate of approximately 1 out of 10 attempts. Here's the command I used:

docker run  -v C:/Users/admin/Desktop/tttt:/loaders-bundle/data -v C:/Users/admin/Desktop/ScienceIslandOSGBSimple_3dtiles:/loaders-bundle/input-data visgl/tile-converter --input-type 3DTILES --tileset input-data/tileset.json --name ttt --output data --split-nodes --slpk --generate-textures

Furthermore, I couldn't locate any textures in the resulting SLPK file. Your assistance in resolving this issue would be greatly appreciated.

Ideally, it would be nice if you could have shared the dataset with us. You can send it on victor.belomestnov@actionengine.com. Have you tried without --generate-textures? It creates 2nd copy of textures:

• If source dataset has jpeg/png, --generate-textures creates basis universal texture in ktx2 container;
• If source dataset has ktx2, --generate-textures creates non-compressed (jpeg or png I don't remember). The source texture is alwo moved to the converted data so you don't necessarily need this flag. Anyway, check without this option and let me know if the result is different.

Resulting textures are located in /nodes/x/textures. There might be nodes without mesh so you need to check nodes with geometry (/nodes/x/geometries should be in place)

Thank you for your help. I discovered that the issue was with my 3D Tiles file. I regenerated a new 3D Tile, but I encountered a new problem. After generating the SLPK using the following command, I couldn't view it in the frontend. It doesn't render correctly in either ArcGIS or Deck (though it did create a "textures" folder). I've sent both versions of the files to the email you provided. If possible, could you please take a look and see what might be causing this issue?

docker run  -v C:/Users/admin/Desktop/tttt:/loaders-bundle/data -v C:/Users/admin/Desktop/osgb23dtiles_test:/loaders-bundle/input-data visgl/tile-converter --input-type 3DTILES --tileset input-data/tileset.json --name qqqq --output data  --slpk

Additionally, I'd like to mention that running the same command still intermittently results in errors. It only succeeds on "lucky" occasions.

[belom88]

I tried your dataset on Ubuntu: npx tile-converter --input-type 3DTILES --tileset ../tilesets/3d-tiles/osgb23dtiles_test/tileset.json --name osgb23dtiles --slpk It looks correct in ArcGIS: You can take a look CLI manual: https://loaders.gl/docs/modules/tile-converter/cli-reference/tile-converter

We will try it on docker. Probably, the issue is related to docker.

Can you tell me which version of Node.js you are using? I've tried both 16.20.2 and the latest version on Ubuntu Server 22.04 LTS, but I couldn't get it to run successfully.

Commands used:

npx tile-converter --input-type 3DTILES --tileset tiles/osgb23dtiles_test/tileset.json  --output slpk  --name linux_zzz --slpk

vbelomestnov@vbelomestnov-ubuntu:~$ node -v v16.20.2 As per https://loaders.gl/docs/modules/tile-converter/cli-reference/tile-converter, have installed dependencies?

[MoCongxin]

yes, have installed.

[belom88]

--tileset tiles/osgb23dtiles_test/tileset.json can be wrong. Try to use absolute link:

/.../tiles/osgb23dtiles_test/tileset.json

Or relative link as I did:

../tilesets/3d-tiles/osgb23dtiles_test/tileset.json

In my case I have file structure:

/home
          /ubuntu
                      /tmp
                      /tilesets/3d-tiles/osgb23dtiles_test/tileset.json

And I ran converter from tmp folder.

[MoCongxin]

I believe it's not a path issue because it has already recognized the 3DTiles file. The complete log is as follows:
