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 ).
Inputs
| Input | Accepts | Description |
|---|---|---|
| 0 | Fibres | Fibres to be scraggled. |
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. |
