Generated 3D tiles not valid according to 3d-tiles-validator

[wonder-sk]

What is the problem?

I have tried to run Obj2Tiles (v1.0.12) using the sample Brighton data, and to verify it is producing a correct dataset, I have used 3d-tiles-validator tool. The tool reported various errors - meaning that the Obj2Tiles probably does not follow the spec in some areas.

What should be the expected behavior?

There should be no errors reported by 3d-tiles-validator

How can we reproduce this?

1. download sample data: https://github.com/DroneDB/test_data/raw/master/brighton/odm_texturing.zip
2. run Obj2Tiles: ./Obj2Tiles odm/odm_textured_model_geo.obj 3dt
3. install 3d-tiles-validator: npm install 3d-tiles-validator
4. run validator on the output: npx 3d-tiles-validator --tilesetFile 3dt/tileset.json > errors.txt

The validator reports various errors - 34 in total - see errors.txt
