heya; with the update you can 1: copy joint parameters across the figure using symmetry (only important if you make figures). 2: have more than 99 morphs on any part (important if you want to sculpt faces with the myriad of morphs available) 3: save more than one figure to the figure library, if they are all linked/parented together (for example, a figure with conforming clothes) -- without hacking a pz3 file. 4: have more group and subset options for saving poses, props, and for exporting objects. (this was a feature actually in the manual, but not in the 4.0 release.) um, that's the points that i need/use/noticed... can't remember if there were any memory leak plugs or performance/stability issues. oh, it will also fix the rattlesnake error message, but you can do that yourself by just deleting the geometry rsr.
