One reason poser my not be used is in crime recunstruction acurate details are important. It is very easy in 3d to manipulate reality thus manipulating the facts of a case. Snce poser has no reality constraint presentations made with it could be taken apart easily in cross examination. An ex boss of mine now works for a lawers firm and helps run the graphics department. In talking to her I've learned that they use the higher end 3d programs because they have reality based physics and measurements. Don't get me wrong I love poser and I think it has many uses but in a court case where reality and facts are paramount the program could be a dangerous tool.
