We are a distributer of MODO in JAPAN. I found that error has occurred with MODO 10.2v2+SketchFab Exporter 2.0 when uploading. Please see a capture movie:
This problem has occurred in our and our customer account.
At 2016/07, we confirmed that we could upload with MODO 10.1v2+SketchFab Exporter 2.0 correctly.
However, I could not upload with 10.1v2 and 10.2v2 today.
Please let me know if you know how to fix this problem.
