Scraggle

The Scraggle node is used to add scraggle, or controlled noise, to the length of a fibre. This is extremely useful to break up fur silhouettes and make the groom look more organic. When Maintain Length is on Yeti will adjust the output fibres to make sure the length remains the same once deformed, otherwise it is likely that the length of the fibres may increase slightly ( in some cases this may be the desired look ).

Parameters

Parameter	Description
Scraggle	The amount of scraggle.
Scraggle Multiplier	Used to modulate the overall scraggle value.
Scraggle Random	Randomize the amount of scraggle on a per fibre basis.
Root/Tip Scraggle	Modulate the effect along the length of the fibres.
Scraggle Frequency	Controls the size of the scraggle effect ( similar to a phase ).
Scraggle Shift	Shifts the scraggle effect along the fibre.
Maintain Length	By default Yeti will try and maintain the fibres length, in some cases this could affect the silhouette of a character - toggling this off will apply the scraggle while still retaining the length from root to tip.
Space	Control if the scraggle is applied using the length of the fibre as a reference space or the parameter of the fibre.
Distribution	Should the scraggle be uniform along the surface or randomized for each fibre.
Percentage	Controls how many of the fibres should have the effect applied.
