Charles River media has a Bryce 5 book out, you can get more details at http://www.charlesriver.com/titles/bryce5.html However, the book is written by Shamms Mortier. I would suggest checking out some reviews on Amazon before buying any books by this author. I do not want to turn this into a flame post against this man, but let's just say, just because someone publishes someones books doesn't make him/her a great author. You might want to try to grab a copy of Real World Bryce 4, by Susan Kitchens. Susan's books are a pleasure to read, and an excellent reference. Most everything in RWB4 still applies to 5, you just won't have any sections on the tree lab or metaballs or any of the new render options. The book lists at $54.99, but check around and you'll probably find it much cheaper online (www.bookpool.com has it in stock and priced at $35.95). Unfortunately, Susan has stated she wouldn't be doing a Bryce 5 book... :(
