Some glb's will not output anything into the data folder

[sweco-sekrsv]

I have a problem with some glb files not being used in the tiler. I have attached and example zip.

Command used:

java -jar mago-3d-tiler-1.10.6-release-natives-windows.jar -input C:\work\3D_tiles\bug_mago -inputType glb -output C:\work\3D_tiles\mago_test6 --crs 3011 --xOffset 151400 --yOffset 6577000

The first glb file is exported from FME (_fme.glb), this works ok and will generate a data folder and a working tileset.
The other one (_gltfpack.glb) have been reduced in triangles, 10% kept using gltfpack (https://github.com/zeux/meshoptimizer). When running this through the tiler no data folder are being created.

Both glb files are loading fine in Blender, Babylon.js Three.js etc.

Hi, @sweco-sekrsv

I've checked both types of data.

I found a problem with the data generated by gltfpack.
The size of the color buffer is not proportional to the number of vertices in that data.
I don't think that's a normal case, but I will add exception handling for such cases in the next patch.

Thank you for your feedback.
