Why should I use poser over the programs that the models are made in As you might imagine, its an old debate around here, but its usually two distinctly different functions (creating meshes & creating images) and, as manoloz suggested, it works best when the tools are suited to the objective. Poser can be a more efficient tool when the necessary elements are already available, allowing the artist to focus more on creating the images, as opposed to the nuts and bolts within each of his set pieces. For example, if an agency needed an image of a woman fastening a seatbelt, few art directors or photographers would consider building their own car or breeding their own actor to be essential requirements for producing the desired shot.
