This parameter allows you to control the softness/sharpness of the bump effect. Parameters can be mapped with other texture.Įrosion – adds some irregularity to the scratch shape.Įrosion Scale Factor – scaling ratio of the size of erosion noise (depends on type of scratches and the size).īump Delta – the texture of scratches produce very sharp and intensive bump. Stretch – stretch factor for the scratch shape (higher value produce more thin shape). Parameters can be mapped with other texture. Spread – density and intensity of scratches. Colors can be mapped: select the bitmaps or procedural maps to appear in one or the other noise color, turn on the checkboxes to make the maps active. Intermediate color values are generated from the two colors you select. Threshold Low / High – When the noise value is above the Low threshold and below the High threshold, the dynamic range is stretched to fill 0 to 1.Ĭolor #1 / Color #2 – Display the Color Selector so you can choose one or the other of the two principal noise colors. Parameter can be mapped with other texture. Size – The dimensions of the noise table.
