sMarble Texture Parameters
            
            
               - Filler_color, Vein_color
 
               - 
                  
                     The
                        colors of the filler material and the vein material.
                     
                   
                
               - Vein_width
 
               - 
                  
                     The thickness or width
                        of the veins. The slider range is 0 to 1. The default value is 0.1.
                     
                   
                
               - Diffusion
 
               - 
                  
                     Controls the amount that
                        the Vein_color blends into the Filler_color.
                        (The Contrast value also affects
                        how the two colors blend together.) The slider range is 0 (no blending)
                        to 1 (smooth blending). The default value is 0.5.
                     
                   
                
               - Contrast
 
               - 
                  
                     The contrast between
                        the Vein_color and Filler_color.
                        The slider range is 0 to 1. The default value is 0.5.
                     
                   
                
            
          
         Noise Parameters
            
            The sMarble texture
               creates a three dimensional texture by projecting a two dimensional
               texture. The Noise Parameters control the
               randomization (using fractal noise) of the texture in the direction
               the texture is projected.
            
            
               - Amplitude
 
               - 
                  
                     A scaling factor applied
                        to all values in the fractal noise about the average value. The
                        valid range is 0 to infinity. The slider range is 0 (no noise) to
                        1 (strong noise). The default value is 1.5.
                     
                   
                
               - Ratio
 
               - 
                  
                     Controls the frequency
                        of the fractal noise. The valid slider range is 0 (low frequency)
                        to 1 (high frequency). The default value is 0.707.
