Ouch. I started with Poser 3, but never heard of this, lucky the Camera files work the same! I have big categories in my Pose Library. The first level of my runtime just designates which version of Poser the file works in, the next is which figure, then its separated by MOR, MAT, and Pose, after that I've even separated files by part i.e. Full, Partial, Head, Eyes, Lips, etc. Do you guys really mean you've still got that many MAT folders? My runtime is 30GB, I thought that was a lot?
