I always wanted to learn Spine and I finally pulled the trigger and bought it. I designed a character and some alternative skins using Affinity Designer (my favourite vector drawing tool) and animated the character using Spine.
The end goal was to have a small fighting game prototype using UFE on Unity, but turns out UFE's animation preview system does not support Spine animations. I wanted to have smooth transitions and slow-mo effects with perfectly interpolated animations so rendering out sprites was out of question. Maybe one day I can code my own fighting game framework and use this character :)
