Hi,
PlayMaker support for Mecanim and Unity 4.3.2 is now out
https://hutonggames.fogbugz.com/default.asp?W1031Demos are missing ( they still can be useful here and there, but definitly obsolete in mayny ways). I'd like Unity to provide a good update on their mecanim tutorial packages... but that's likely not for tomorow unfortunatly. I'll see what I can do with the GDC mecanim demo, it has some stuff, but not covering everything unfortunatly.
So, don't hesitate to report issues and all, not every actions where tested ( cause some actually makes no sense yet to me... and Unity doc is missing or not useful for a proper understanding).
Bye,
Jean
