Hi 🙂
It seems that unity "Apply Regions as Texture Sprite Slices" of unity runtime does not work.
1."Texture packer" on Spine.
2.Atlas and packed texture import to Unity.
3.Click "Apply Regions as Texture Sprite Slices" button.
4.I get an error on the console and slice is not correctly.
Versions:
Spine 3.5.43(latest)
Unity 5.4.2p1
UintyRuntime 20161209(latest)
I have attached the sources files. 🙂
