Mr. Mortier's books tend to be somewhat simplistic as well as error prone. They rarely contain any information that readers will not discover for themselves by simply stumbling through the program. The examples he uses to illustrate a subject tend to be somewhat... ummm... bizarre. If you wish to create scenes reminiscent of a drunkard's nightmare then his advice might be exactly what you are seeking. The subject of his books crops up from time to time in the Poser and Bryce forums. Rather than rely upon my clearly biased opinion you may wish to do a general search with his name as a keyword. You will then be in a better position to judge for yourself. You may be shocked at how many share my opinion in this regard. At the very least, if you are considering one of his books I would recommend first browsing through it at a bookstore. BTW, the books of his that generate the most favourable comments tend to be those where most of the chapters have been written by others and he has merely compiled them. In contrast Real World Bryce is packed tightly with solid information and it will take you considerable time to do justice to it. It will tell you how Bryce really works as opposed to what the manual claims to work. You will learn work arounds to various problems as well as a variety of techniques. While RWB is a very practical text it does not completely ignore theory either. I would almost be tempted to say that if you have Bryce but do not have this book then you only have half a program. - Jack
