I'll try to make a 3D path finding behavior in the next update, and about sprite animations, I've tried to mimic the C2 animation frames behavior but I failed because the Babylon engine uses a different approach, it loads an entire spritesheet in divides it into cells, so in order to make it work, I'll need to hack my way into the library itself and adjust the code, so It will take me a while before getting everything to work right.
What you all need to know for now is that the next update will please you a lot. There are some new features that will make designing levels in C2 a lot easier.
