## Overview

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.

## Inputs

Input | Description

0 Data Flow | Fibres

## Direction

Parameter | Description
--- | ---
Weight | The amount that the fibres follow the direction.
Random | Randomizes the direction.
Roll | The roll, or amount of rotation around the main axis ( Normal ).
Inclination | The inclination, or amount of rotation around the secondary axis.
