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).

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.
