Hi,
I met with the guy actually
I was at Unite too, a very nice person!
His stuff is pretty advanced actually. I haven't planned personnaly to try and port his work and make it available for PlayMaker, but this is surely something that would be very interesting to experiment with. You should contact him to mention your interest in a PlayMaker support of some sort and see what's his point of view on this.
Bye,
Jean
ps: Something truke me at Unite. Basically, it's going to fast now!! the amount of incredible stuff coming out from Unity and the asset store, makes it totally impossible to fully cover... I am not sure there is an easy way out of this trend... I remember being able to catch up pretty much with Unity new release on 3.x iterations.. now it would require several full time developers to even barely catch up with unity 4.x releases and the best assets on the store to provide full support with PlayMaker... scary!!! So really, if you see a great thing on the asset store or something, it's always a good thing to tell us your interest in this but also to contact the author as well, so that collaboration can be made to bring you PlayMaker support.
