划痕

The Scratches Node can be used to generate randomly placed, scaled and rotated scratches. The density of these elements can, among other settings, be defined by the number of layers. If this setting is varies across a progression of brightness, as in this example, the number of scratches on the surface can be controlled very easily. 抓痕节点可以用来产生随机放置，缩放和旋转抓痕。除其他设置外，这些元素的密度可以通过层数来定义。如果这个设置是不同的亮度进展，在这个例子中，表面上的划痕数量可以很容易地控制

This Node can be used to create black, randomly placed lines on a white background. The effect can, for example, be used to simulate scratches on a surface.
