Let me try to answer a few questions...but keep in mind, these are my personal experiences, so don't quote me on it when the P5 retail box says different things. Computing power required: If you want to use the new hair stuff (and I know you want), RAM is what you should upgrade first. Hair really eats a lot of RAM. My personal recommendation is to use Win2k or WinXP, as the 9x series is really bad at handling larger amounts of RAM. Regarding the CPU: Of course, faster CPUs will give you faster rendering. However, a fast CPU needs RAM to play in, so if you have a 800MHz computer with 256 MB RAM, upgrade your memory first, then the CPU. The putty tool: It's the way you always wanted morph targets to be. Well, at least the way I wanted them. To Little_Dragon: Yes, that's the way the hair stuff works.
