So With the images below I was experimenting with AO( ambient Occlusion ) http://en.wikipedia.org/wiki/Ambient_occlusion pass materials In hopes to gain a better use of the parameters used like variations of the samples and max distance for different materials. Normally just one version of this material is made then applied to the material override key. Applying the one variation of itself over all the objects in a scene. Which is later filtered over the same color image as a blend mode in an image editing program to add more depth and shade to objects. This effect rids the image of what some call floating objects. You'll notice as well some plastic material used for the CD case and glass in the stereo because I did not turn of the FG ( finial Gather ) http://download.autodesk.com/us/maya/2010help/mr/manual/node52.html Normaly AO passes don't require global illumination or FG so these functions are turned off. However by not turning them off I am able to use other materials in the scene as well.
