actually it’s already ported for quite a while. 😉 With the shift to Qt 5 we moved the plugins out from V-Play Game Engine to standalone plugins to be able to use them without the engine features too (e.g. for business app development). You can find all information about the plugins here: http://plugins.v-play.net
Regarding pricing, the plugins are still included in our V-Play Game Engine subscription plans like in 1.x versions, please send us a message to email@example.com if you want to use a plugin in one of your V-Play 2 games and we can send you over a license key.
