The book is fantastic. They really did a very in depth study of the application. The only thing I have become disapointed in regarding either Bryce Real World 2 and 4 are that the companion web sites and resources that way are not happening. Antialas dropped from the world and she isn't to be found anymore too (Susan Kitchens) that is. Sorry to read that you suffered an injury of that order and am certainly hoping that you are much better since then... The terrain and Tree Labs in version 5 are a fantastic addition enhancement but hold onto version 4 since the render times are much faster for the most part. Good luck with what you do!
