@SCIA this is great work! Actually I am planning a similar project with a small Team of 3 Developers. I haven't worked with Spine so far and I have to figure out, how to create one Character Rig which will be reusable for different Skins and Equipment. Just like you did.

I am really interested in your project files or more information about your workflow in Detail.
Is there any chance to share this?

Cheers
