This node is based on the 3dsMax Weave OSL shader.

The Projection input has to be connect to a projection node for the shader to work.
The other inputs correspond to the controls exposed in the panel.
Returns the final output colour of the threads on top of the background colour.
Returns a random ID for each thread
Returns the opacity of the threads. If Opacity Fade is set to 0%, this is essentially a mask for the threads. If it set to 100%, it includes the effects of the Round Shadow and the Weave Shadow settings.
Returns the displacement due to the threads.
Since the shader renders fibres on top of a background, this allows you to define the background colour.
The spacing and scale of the fibres. The smaller the scale, the more there are.
The colour of the fibres along U and V.
The width of the fibres as a percentage to the next fibre.
This is used as the base for the noise function used to randomise some of the settings, such as Frizz and Bendyness. A different seed will retain the same general style but with different distributions.
This tints the fibres to add pseudo-shading to make them look round.
This works in conjunction with Round Shadow, both need to be higher than 0% for en effect to be seen.
Round Shadow defines the strength of the shading, the Roundness how much of the fibre is covered.
Adds this much displacement due to Roundness to the Displacement output.
Adds a fake, ambient occlusion style shadow to the Roundness shading.
Adds this much displacement due to the weaving to the Displacement output.
Adds a fake, ambient occlusion style shadow of the top fibres to the ones underneath it.
This changes the width of individual fibres along their length.
This controls the the frequency of the change in width.
This randomizes the width of the fibres.
Controls the frequency of the Bendyness.
