Don't let you hinder by all the talk about DAZ Studio which is not there at least yet. I think any in-depth description of architecture and technology covers more then just one application. As an example: a deeper understanding of shaders, how they work, how they interfere with lighting, etc. would be of use not only to the users of Poser5 but of any similar application. Down by the the riverside, it's all about bits and bytes, vertices, normals and so on. OK, where can I put my order? Willy
