Hi,
we've also added a Spine runtime for Qt, Qml & V-Play and have written a step-by-step tutorial how to use spine animations with QML & V-Play.
You can find it here:
http://v-play.net/doc/how-to-add-spine-animations-to-your-vplay-game/
Would be cool if you can also add V-Play to the supported runtimes list.
Cheers,
Chris from V-Play
