Good Morning . . . 8^) Just a quick message for Tesign & MightyPete, in your posts on this thread you sounded like you had negative feelings about, having to have a new key or serial number each & every time you have to install or re-install a software program, used as it's security protection. Also, I believe you both stated you had desires for owning Zbrush 1.5. Well, not to bust your bubbles or anything like that, but I've had Zbrush for almost 2 years now & that's exactly the type of security protection they use for Zbrush! During the first 1 & years of use the serial # continually expired. So you couldn't use it until you e-mailed Zbrush to obtain a new, ( different ) one, each & every time. When the year 2002 occurred, Zbrush quit working for all users & you had to e-mail for a new serial # to use Zbrush. Now they have the new 1.5 version out for almost 2 months now & serial #'s have expired once again. So, if you do purchase Zbrush, this is something your going to have to put up with. Every single time you re-install Zbrush, for what ever reason, your going to have to e-mail for a new "security protection" serial #. One final point I might mention, there have been several posts on their forum about Zbrush using, " 100% " of your processor power continually while Zbrush is open. Myself & several others have complained to Pixologic about this problem, but they won't admit to this being any type of a bug or problem. All you have to do is open Zbrush & do nothing more, & your processor is running at 100%, more than any other software I've ever used. One user has complained that he was using Zbrush on his Athlon powered laptop, & when ever Zbrush was open, even just sitting there doing nothing, his laptop started getting red hot, after about 10 minutes, due to the 100% processor usage. But Pixologic still claims there are no bugs or problems with their software. Anyway, just thought I'd throw this tad of information your way, & you guys have a good one . . . Mark ;^) PS: ( IMHO, I think $400.00 is a little too much to spend for Zbrush, for what it will do. )
