If the model fails to convert, it should be caused by texture. I use 3dsmax to export the model to obj format, remove the texture, and convert the model to...

It was verified again today that the UV coordinate cannot exceed the range of 0~1, otherwise, a texture coordinate error will be reported. Here is the test model: [model.zip](https://github.com/OpenDroneMap/Obj2Tiles/files/9884408/model.zip) 

Some models will lose texture after successful conversion. For example, this will happen to the above 01.obj model

When I set the value of --divisions to 3, no json file is generated, but the model file is generated.
