Hi,
Currently on going! I have actually the Unity demo opened and currently disecting everything to fully port this to PlayMaker.
We have few considerations and standards to get right first, once we have a direction, I will proceed and create a bridge for implementation in your own projects, as well as the unity demo fully done in PlayMaker.
So stay tuned! It's coming real soon and currently the top priority with Mecanim and Pathfinding leveraging.
bye,
Jean
