Hello,
I've been working on a simple platform engine using Spine for Starling.
Spine exporter and texture packer are great! but only produce LibGdx atlases.
You would need to repack the textures in the Starling format.
Why convert when you can code?
Here's a very quick and dirty way to "support" the libgdx format. It only reads xy and size.
It's just a proof of concept for Nate to see...Maybe an official implementation will follow? Plz Nate?
Note : Copy-paste broke some indentations
