Maps any image input onto an object (such as a shading network, or a file texture). You can mask the input image to control
            how it covers a surface, to overlay different textures and control what parts of the texture are visible, or to label map
            a surface.

                   Controls the sharpness of the texture edges. The default ’s color is the color of the edge blend. Increase this value to blend edges softly.

                   Represents the ’s transparency. Use to control the overall transparency of the entire texture. To control the transparency of selected regions
                     of the texture, map another texture to . 
                   For example, this is what happens when you map a texture to the  attribute.

                       Enables or disables  masking. When on, Maya selects the areas in the texture similar to or equal to the  color and masks them out. When off, all other key attributes have no effect.

                      Inverts the chroma key mask (only the colors specified in the  and  are displayed). The default setting is off (the colors specified in the  and  are masked).

                      The color to be masked in the texture. The default setting is black. To mask a range of colors, you must also set the  parameters.

                      The range of hues (H) centered on the  color which are also masked. The valid range is 0 to 1. The default value is 0.5.

                      The range of saturations (S) centered on the  color which are also masked. The valid range is 0 to 1. The default value is 0.5.

                      The range of values (V) centered on the  color which are also masked. The valid range is 0 to 1. The default value is 0.5. If you want to mask out the exact key color,
                        set V to 0.
