Hi all, a made it a bit easier if you want to use ArtRage in your workflow with this ArtRage>Spine script. Please find all the instructions and download information below the video (on YouTube).
The script is quite simple; it just crops each of your layers and exports them individually as a separate file named the same as your layer. Like all these scripts, it saves having to do the whole monotonous process every time you want to make a change. Just one button press will export everything.
Setup: Just copy the script file into your ArtRage/Actions folder to see it appear in your actions list.
Enjoy
