@Erwin : If you are using the demo version it's normal that you don't have the "poser return" working : it's the ONLY limitation of the demo. It"s with the full version that you can have the Poser update after a simulation. It's also written somewhere in the manual, if we could do it with the demo why would we buy the complete version ?

I tried my first simulation with hair and I'm quite happy with the result, I hope to post a result soon.

I read carefully the tutorial in the manual and have done exactly the same with a basic scene to get the tool principles and only after I tried with my own project. It's also a way to define my workflow with the other soft I use. I must said it's the fourth time I read it completely and each time I learned something new!
