Scale scales the hair, including its form, and does not cut it off." --- ## 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. ### Scale Parameter ID: `HAIRMATERIAL_SCALE` · Range: [0..+∞%] ![Image: 005214.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/005214.jpg)\ 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` ![Image: 005215.jpg](https://help.maxon.net/c4d/en-us/Content/Resources/Images/005215.jpg)\ In the example above, a grayscale gradient was used to scale the hair.
