Hi,Oh mate... We already knew that. It's been mentioned multiple times on here. A member called "Bones" kept posting about it in a couple of threads or so a few months back - I don't remember if he mentioned how to use them though, sorry.
I have heard, Visionaire supports Spine animations. Yesterday I found out, that the Open Source and free to use animation program "DragonBones Pro" (http://dragonbones.com/en/index.html) can export Spine files easily (Spine versions 2.1 and 3.3 are supported). With that everyone is able to produce Spine animations without any costs (register via e-mail is the only thing you need). It worked, I have tested it. I got the following export files of my test animation:
Now, how we use these Spine animations in Visionaire? Is there a tutorial or something like that?
