Hi IO4,  Bryce, Vue, Poser, and Carrara have basically the same format ie the Romance languages so getting refamiliar with Bryce won't be that difficult.  What's painfully difficult is ZBrush.  Sort of like studying the Romance language and up pops Chinese that the only thing that ZBrush has in common with my other software programs is Cntrl Z that works most of the time-except when it doesn't.  Jan
