OBJ model conversion failed

[jingyangking]

First of all, thank you for contributing such a great tool. Secondly, my question is: My OBJ model was exported through Blender, and I have also tried to import it back into Blender or 3dmax, and it displayed correctly. The model should not have any problems, but why did I report an error when using this tool to convert it to tiles: Exception: Element not supported:'l 62675 62676 '? Is it because the model is too large that it cannot be converted, or is it due to other reasons? I hope you can answer this. Thank you

Also, after the model conversion, it seems that the attribute information in the original components is gone. How can we save this attribute data?
