I did not have this problem before the latest Spine update. Now, when I export my animations, four parts are not detected in the atlas when I export to unity and as result I can't create a skeleton. It's always the same parts but I don't know what's causing it; the parts are attached to bones but some are attached to animated bones and some aren't. I use numbers in my part names but no underscores.
The game won't detect:
"neck fur"
"top beak accessories"
"top beak back"
"fur head back"
and I have no idea why. The skeleton exports just fine if these are removed, but I obviously need them to not be removed.
My settings are attached. I haven't changed them at all, but maybe the update did?
