Leather Texture Parameters
            
            
               - Cell Color, Crease Color
 
               - 
                  
                     The
                        color of individual cells (Cell Color)
                        and the medium surrounding the cells (Crease Color).
                     
                   
                
               - Cell Size
 
               - 
                  
                     The size of individual
                        cells. The Cell Size value effectively scales
                        the entire texture. The valid range is 0 to infinity. The slider
                        range is 0 to 1. The default value is 0.5.
                     
                   
                
               - Density
 
               - 
                  
                     Controls the spacing
                        of cells in the texture. The valid range is 0 to infinity. The slider
                        range is 0 to 1 (fully packed). The default value is 1.
                     
                   
                
               - Spottyness
 
               - 
                  
                     Randomizes the Cell Color intensity.
                        (The Threshold value also influences
                        the Cell Color intensity.) The
                        valid range is 0 to infinity. The slider range is 0 (all cells have
                        the same intensity) to 1 (cell intensity is entirely random). The
                        default value is 0.1.
                     
                   
                
               - Randomness
 
               - 
                  
                     Randomizes cell position.
                        The valid range is 0 to infinity. The slider range is 0 (cells are
                        arranged in a regular 3D lattice) to 1 (cell location is entirely random).
                        The default value is 0.5.
                     
                   
                
               - Threshold
 
               - 
                  
                     Controls how much the Cell Color and Crease Color mix
                        into each other. The valid range is 0 to infinity. The slider range
                        is 0 to 1 (no mixing, cells appear as solid color dots). The default value
                        is 0.83.
                     
                   
                
               - Creases
 
               - 
                  
                     Creates boundaries between
                        cells that resemble the creases in leather. If Creases is OFF,
                        the cells diffuse uniformly into each other. The default setting
                        is ON.
