I've just updated my Spine Editor to 3.6.48. After exporting to my Unity project, my textures are looking like this the screenshot below. I'm using Unity 5.6.4f1 and 3.6 Unity Runtime (Compatible with Spine 3.6.x and Unity 5.6-2017.2 (Last updated: UTC - 2017 November 25) )
Is there a known way to fix this?
