You can't make nested dirs in poser 4/PP, but there are ways to make life easier. 1. Name your folders using numbers + names. Like... 001 - current project 002 - stuff I use a lot 003 - stuff I use not quite as much That means when you open Pose (or any other library) 001 will be the first folder you see. Numbers take precedence over uppercase, uppercase over lowercase. You can go from 001 - 256. 2. Get rid of the ones you don't use. I have 2 Pose folders, 'Pose' and 'Pass'. All the Poses or MATs I'm using stay in Pose, everything else is left in Pass until I need it. The folders are right next to one another in Runtime/Libraries, but Poser won't see the second one. mac
