Well I wish you the best of luck ZewbiBrusher!
I’ve made a couple of 300 page ZBrush PDf’s from this forum and the previous forum before the ZBC. I’ll tell you now, it’s a full-on job!!
Unfortunatly just about all the information in them is well and truely out of date these days so they are no longer availiable. Some careful hunting around on the net might uncover them?
Some tips I can offer is that you must respect the original poster’s work and quote them 100%, and do not mess around with their art work, unless you are resizing it for page-layout purposes. You also have to test every claim on ZBrush to make sure the tutorial actually works!
In some threads there are several different ways to do the same thing, which can lead to confusion, and head-aches. Then make sure you have written permission from every poster. (this was the easy bit!)
You must also make it clear that the ZBrush Central web forum is your source of information, and have the web address and logo clearly thoughout the PDF.
Any threads you compile from here must be clearly referanced to the number of the tread.
Also with an upcoming ZBrush version on the distant horizon, it is best to make sure that you “future-proof” your PDF with relevant topics that you “guess” won’t become outdated too quickly. Have you downloaded the seek-peek movies from the Pixologic web site?
All that said, if you accomplish these hurdles, you deserve to send the PDF off to print, and make the first commercial ZBrush book! I know somebody else did that a couple of years ago for the Combustion Software web warriors
I’m working on a online ZBrush resources page which I quickly compiled last weekend. You’ll have to join my ZBrushers email list to get access to it first!
Again, best of luck!
