Our little studio has been using Anima2D for character animation for the past month or so. While we like keeping our work within unity as well as the price, we have been finding a few things about Anima2D/Unity that interrupt our production -- whether it's an issue with the IK limbs not sticking right while animating via Unity's animation tool or just the Unity learning curve for artists. We have been pondering whether we should take some time and money and give Spine a try or just tough it out with Anima2D/Unity but before we do, we were hoping to hear opinions from anyone that has worked with either product. So, in your opinion: Spine or Anima2D and why? Your thoughts are appreciated!
