## Scale

Don't mix the **Scale** channel up with the **Length** channel. **Scale** scales the hair, including its form, and does not cut it off.

The part in the example above was rendered, from left to right, with **Scale** set to 40%, 70% and 100%, respectively.

### Variation

Parameter ID: `HAIRMATERIAL_SCALE_VAR` · Range: [0..100%]

Use **Variation** to define the maximum random variance in the scale of the hair. A value of 0% will scale all hairs equally.

### Amount

Parameter ID: `HAIRMATERIAL_SCALE_AMOUNT` · Range: [0..100%]

Use this slider to define to what degree randomly selected hair will be affected by the other **Scale** settings.

### Texture

Parameter ID: `HAIRMATERIAL_SCALE_SHADER`
