Scratches node ~~~~~~~~~~~~~~ The **Scratches** node outputs a fibers pattern, that can be used for scratches on any material or messy fibers. It is inspired from a the *Fuzzy scratches* shadertoy from Daedalus (https://www.shadertoy.com/view/4syXRD). .. image:: images/node_scratches.png Inputs ++++++ The **Scratches** node does not accept any input. Outputs +++++++ The **Scratches** node generates a single greyscale output texture. Parameters ++++++++++ The **Scratches** node accepts the following parameters: * the *Length* parameter defines the length of a fiber in the output texture. The number of scratches grows exponentially with the inverse of this length. * the *Width* parameter defines the width of each fiber. * *Layers* is the number of layers of the effect. The number of scratches grows linearly with the number of layers. * *Waviness* can be tweaked to draw straight or curved scratches. * *Angle* is the average angle of the scratches. * *Randomness* is applied to the scratches angles.
