The complete User Guide and Reference Manuals are included in the Documentation folder. The 3r5 Manual is in the 4.0 ‘whats new guide’. Don’t be fooled by the Document file names, these are actual addenda to the original manual.
4R7 is the last version of what started out as Zbrush 3.5. The original User Guide and Reference manuals were written for Zbrush 3.0.
A new user, starting out with v.4R7 will best be served by reading the (appropriately named) “Zbrush Starting Guide”. Followed by the 3.5 user manual and tutorial manual, then progressing through the 4.0 manual and tutorial guide. From there proceed through 4R2, 4R2b, 4R3, 4R4, 4R5, 4R6 and 4R7 “whats new” guides. These are actually User Guide and Reference Manual Addenda. Also read through the 4.0 Tutorial Guide.
After that read through the Plugins Documentation. Unlike the current Online Docs, almost every feature is illustrated in the PDF Manuals.
The Online Docs are also very useful and easily searched.
When Pixologic has it ready for download, the “Getting Started with ZBrush 4R7” Guide will also be very helpful to the new user. (the current Addendum is still 4R6). The advantage to this document is that it is laid out in a progressive learning sequence with illustrations and links.
Although the links may not yet be officially posted for the 4r7 Keyboard ShortCuts and 4R7 CheatSheet, you can download them here;
http://docs.pixologic.com/wp-content…-Shortcuts.pdf
http://docs.pixologic.com/wp-content...atSheet4R7.pdf
But the best in-app documentation in the business can be found in Zbrush itself. (illustrated, no less!) Hover the cursor over a GUI element and alternately press the Option and Command keys. (or Windows keyboard equivalents).
And, of course, the ClassRoom videos are essential learning tools, that can also be downloaded for ‘‘off the grid’’ viewing. I use a utility called SWF & FLV Player to download the videos for offline viewing. I use VLC app for playback of .f4v videos. (cross platform)
I also found the “Industries” pages inspiring and informative; http://pixologic.com/zbrush/industry/
And also the “Features” pages including examples and links, were helpful;
