# Bend

## Overview

Bend is used to bend fibres either towards or away from the surface, the reference frame of this surface can be altered by specifying new Normal and Up Vector values as well as the bend direction to vary the result.

## Bend

Parameter | Description
--- | ---
Bend | The amount of bend.
Bend Multiplier | Can be used to multiply the overall bend value.
Bend Random | Used to randomize the amount of bend on a per fibre basis.
Bend Direction | A means of rotating the bend direction on a per fibre basis.
Normal | The attribute used to define the surface normal, this along with Up Vector is used to define the direction of the bend.
Up Vector | The value for the up vector, by default this is the Y axis but this can be a varying attribute to randomize the bend direction.
