The Direction node can be used to adjust the overall direction of Fibres, the reference frame of this surface can be altered by specifying new Normal and Up Vector values to vary the result.

Parameters
| Parameter | Description |
|---|
| Weight | The amount that the fibres follow the direction. |
| Random | Randomize the direction. |
| Roll | The roll, or amount of rotation around the main axis ( defined by the Normal parameter ). |
| Inclination | The inclination, or amount of rotation around the secondary axis ( tangential to the Normal parameter ). |
| Normal | The attribute used to define the surface normal, this along with the Up Vector is used to define the frame of the direction. |
| Up Vector | The value for the up vector, by default this is the Y axis but can be a varying attribute to randomize the direction. |
