After saving dynamic hair in library with a character and loading it in another scene, if I use dynamics with do collision checked, the computer hang (or perhaps the calculation take so long time that it seems hang); the problem doesnt arise if I save the character as .PZZ (or .PZ3) and import it via File>Import>PoserDocument. The problem arises also if I save the hair alone (with skullcap). Does someone have the same problem? I hope you understand what I wrote: Im Italian and my English isnt very well.
