LuniqueKero Thank you for sending us the Spine project file! Your configuration of cropping and using part of the 12288 * 8192 px image would have caused the export to take so long that I would have thought it was frozen. In fact, even without exporting, just looking at your skeleton in the editor took a long time to load. (By long, I mean only 10-20 seconds, but I can say that the loading time is quite long, since the appearance of a skeleton should generally be seen as soon as the Spine project is opened).
What makes you use such a huge image like this for each attachment? You could just accept long export times, but I think it would be better to modify the skeleton to make it easier to export.
