Depth Cue rendering is possible, although most don't like what it does. I think theres also a lack of understanding regarding the depth cue and maybe someone with some time should write an indepth tutorial on it. From what I understand of Posers depth cue feature is this; you can control the colour of the fog using the background colour tool, you then have fog which is disperssed evenly between the nearest obj and the furthest obj in a scene. The best way I have found to manipulate thsi effect is to take two cubes(primitives) and place them off camera, one furthest fwd in a scene and the other furthest back, you can then adjust the depth cuing that appears in the final render :) There are a few other tricks that cen be used also but likei said someone with a bit more time can maybe write a tut on this :)
