It's only half-baked. Material room is nice. Hair room is too confusing and the results are too wiry. Haven't played with the face room because it only works on Don or Judy, not even with the kids as far as I know. The thing is, the program is freaking slow! 1.7Ghtz, 512 MB of RAM, and it takes several seconds to switch to and from the Pose room, up to 30 seconds. Light sets crash it. God forbid P5 can't find a texture! The nested libraries are wonderful, but P5 is slow and pokey just to bring up the libraries, let alone load something from them. The parameter dial is nice, but it is buggy as well. If there was a 3rd party program that allowed me to keep the nested libraries I have and use P4, I'd switch back in a heart beat. (I know that there are programs that allow you to switch folders in and out, but I want to keep the folder organization as is and just have it frickin' work in P4.)
