Stucco is a 3D map that generates a surface pattern that is useful for bump mapping for creating the effect of a stuccoed surface.
Size—Adjusts the size of the indentations. Use this to make the scale of the stucco match your geometry. Default=20.
Thickness—Blurs the border between the two colors. At 0, the borders are sharp. The higher the Thickness, the more the borders are blurred and the less distinct the indentations are. When you use Stucco as a bump map, the indentations are very faint at 0.5 and disappear at values not much greater. Default=0.15.
Threshold—Determines how much of Color #1 is mixed with Color #2. At 0, only Color #2 is displayed; at 1, only Color #1 is displayed. Default=0.57.
Swap—Exchanges the two color components.
Color #1—Represents the color of the indentations.
Color #2—Represents the background stucco color.
Click one of the swatches to display the Color Selector and change one of these component colors.
Tip: Because the Stucco map is meant to be used as a bump map, usually you don't need to adjust the default colors.
Maps—Assigns a map to replace one of the color components. Turning off the check box turns off the associated map (the Stucco map reverts to the associated color component).
