Hi there,
Since it's my first post, I'll begin by thanking you for your work. Glad we finally have a good 2D animation tool 😉.
That being said, I'm working on a 2D engine from scratch. I'd like to use my own intermediate format to avoid strong coupling with tools.
Right now, I'm using a simple script to translate the json export before to paste it in the game folder. That's not so bad, but it would be awesome to have the possibility to extend export formats.
Something like : you paste a (lua/python/javascript) file in the Spine folder so you can select it in the export popup and it's executed with the Spine DOM as input.
Cheers
