Model will be avaliable to download in the next few days.
The concept behind the DSU is to simulate distance in Poser, in the simplest way possible.
Plus to do this without bogging down the system with large meshes.
Another factor in it's creation was to use standard sized (4:3 aspect ratio) digital photographs straight from a camera for the planes without having to crop or resize the photographs.
The background is mapped at 4:3 and the ground is mapped at 4:3x3. So for example, you could use one photograph at 1600x1200 for the background and use 3 copies of an 1024x768 image (making 1 image at 1024x1365) for the ground.
As folks use Poser for single figure shots, the long ground was created so you easily may place objects behind your figures. For example bushes and trees. However there is a finite limit (roughly 2/3rds back from the backdrop) you can draw back on the camera, even at a high focal of 70-100, before the edges of the background will show.
So the trick for creating large scenes is to load the DSU mutiple times. The sides of the DSU (unlike on some commerical products) are not curved or warped but flat. So you can load 3 or 4 copies, texture each one and and move it along left and right with the parameter dials. The distance between each copy is roughly 1.6 units on the X trans. Just jiggle it to suit :)
Another feature of the DSU is it's thinness. This allows (mainly) the background to be transmapped. Then you can place objects behind the background, which is a particulary cool effect for animators. Obviously the grey background of the poser window will show, so you just import a background picture of a sky.
If you load the included MAT pose "02_Mountain_T" and use "01_Clouds.jpg" as the background Picture for Poser. You can see this effect.
Another fun use for the DSU is to make a render and use that as the background image. Again a sample of how easy this is included. Just select the DSU in the scene window and load the "02_City_Ruins" MAT from the Poses Libary.
