The decay map is based on the angular decay of the normals above the geometry surface to generate values from white to black. The direction used to specify the angle attenuation changes with the selected method. However, according to the default setting, the map generates white on the normal from the current view to the outer surface, and generates black on the surface of the normal parallel to the current view. Compared to the attenuation settings of the standard material "extended parameter" volume scroll, the decay map provides more opacity attenuation effects. You can specify the attenuation map as an opacity map. However, in order to achieve special effects, you can also use "attenuation", such as rainbow effect. Analysis: Front side: by default, the front side is the name of the group at the top of the scroll bar. "Front: surface" means vertical / parallel attenuation. The name will change depending on the selected attenuation type. In any case, the name on the left refers to the group of controls at the top, and the name on the right refers to the group of controls at the bottom. Click the color swatch to specify the color. Use the spinner to adjust the relative intensity of the color. Click the button marked "no" to specify the map. Enable the check box to activate the map (otherwise the color will be used) Attenuation type - select the type of attenuation. These include five options: Vertical / parallel - set the angle attenuation range between the surface normal to the attenuation direction and the normal parallel to the attenuation direction. The attenuation range is 90 degrees based on the normal direction of the surface. (default settings). ) Orientation / deviation - sets the angle attenuation range between the normal face of the (Xiang Pinghang) attenuation direction and the normal of the deviation from the
