Susan Kitchen's Real World Bryce 2 was indispensible: Brycers all over the world referred to it simply as "the book". RWB4 was originally going to be RWB3, but a further upgrade took place on the way. RWB4 has been much delayed, and re-writing was going on as recently as two months before its final publication. It's taken a long time to make it to print, but it's been well worth the wait.
Susan and Victor have written a book that anyone writing a third party software manual should study: it's clear, it's concise (despite its 900+ pages - Bryce is a hefty and versatile piece of software!), it's easy to read.
No "see the manual for further details" here! The authors frequently refer to the manual, but mostly to point out where the manual and the software differ. Here, then, is the real manual for Bryce 4.
Throughout the writing of the book Susan regularly consulted with Brycers, sometimes through Bryce Talk, sometimes through various mailing lists, to talk over various points she covers in the book. She also gave the programmers the third degree!
Until two weeks ago, when RWB4 arrived, RWB2 lived beside my monitor - much of what it says is equally applicable to Bryce 3 and Bryce 4. "I'm using Bryce 4. If that's the case why should I bother with this new book?" Because there's too much that's new for you to ignore this book! It's twice the size of RWB2, the seedy-rom is packed with examples, it covers animation and volume materials, and if you've had half the value of RWB2 that I have, you must be getting pretty sick of the book falling apart!
Forget any other Bryce 4 book: THIS is the book you need!
