What is the problem?

when i use Obj2Tiles to split my obj file have a exception ：Exception: The number of sub-mesh material names does not match the count of sub-mesh index arrays.

What should be the expected behavior?

Please tell me , why this exception happened, and how to solve it. If it is the format of the Obj data itself, please give me an answer. Thank you very much!

How can we reproduce this? THIS IS IMPORTANT. What steps did you do to trigger the problem? If this is an issue with processing a model, YOU MUST include a copy of your model uploaded on Google Drive or Dropbox (otherwise we cannot reproduce this) along with the command line parameters you used to process it.

So for me the issue was that the OBJ has several materials defined, however, one of the materials was right at the end of the file and no faces/triangles were assigned to it (it was just a default material). Simply removing the last line (usemtl blah_blah) of the OBJ file fixed the problem. I guess it would probably be better for the converter to log a warning instead of failing perhaps.

I also encountered the same problem, the display grid material and index array do not match. Have you resolved it

When I export the model as OBJ, I can convert it well when I choose materials and UV textures that are not retained, which means the main reason lies in the texture and material
