For all Unity folks who are exporting quite a bunch of Spine projects into Unity we have developed over the years IntegratorTool2D
What it does is that it centralizes all your spine projects in one convenient export import tool ( IntegratorTool2D )
It also takes care about exporting PS or AI files as dissected pngs and is capable to take those dissected images to be reconstructed back again in Unity or Spine.
I will post soon simple video showing easy to follow workflow that is relevant to Spine Unity production.
The most powerful thing of this tool is that you can manage international team of Illustrators and Animators thanks to feature that your PS, AI and Spine files can reside on cloud based service like Dropbox.
