I use Spine 3.8.76
Normally, exporting my project from Spine editor to Json/unity takes 30 seconds.
Export settings are standard. The only change is that the scale of images is 0.5.
Everything works.
In the folder with exported data 1 png picture (image atlas).
In the Spine editor I added more pictures to my project.
I have not changed any settings.
Exporting this project from Spine editor to Json/unity took 10 seconds.
There are 2 png images (image atlas) in the folder with exported data.
The error in the Unity editor is Attempt Reimport.
By feelings - the matter is in the editor. Images on png pictures with exported data do not exceed the size of 1024x1024 (fits into the standard compression setting of 2048x2048).
Exporting a heavier project is 2 times faster - indicating an editor bug.
Is there a bug or fix for this version of spine or do I need an upgrade?
