I am having issues when trying to import my Spine project to Unity. I have tried with the example Spineboy project and I have the same issue. When I go to export, I set Texture atlas to Pack, and I tried both the "Attachements" or "Image Folder" option. The problem is when I import my .json to Unity I get the error that I have missing Atlas and that the SkeletonDataAsset has missing regions.
Basically, my generated Atlas file seems to not be readable. How would I go about fixing this? I did some searching but the solutions like renaming atlas file to atlas.txt didn't help.
Turns out I had to pack using the "Attachments" option, change atlas extension to .txt, and then manually drag atlas, .json and .png to Unity. Probably dumb of me but I don't remember having to do this stuff before.
