nkseok90 Welcome to the Spine Forum! I would like to tell you first: This forum has a translation button.

As for the reason for the texture packing error, I think there is something wrong with your mesh settings, since the error only occurs during polygon packing. For example, you may have inadvertently left some vertices outside the mesh boundary, which can cause the export to fail. Could you please check for such vertices errors? Or you can send us your Spine project via email and we can check on the cause: contact@esotericsoftware.com
According to the error log, it seems that the body2 image cannot be packed properly, so you can send us spine project files with only the attachment where the body2 image is used, and delete everything else.
