Noise Frequency

Noise Frequency determines how often the pattern within a texture repeats. Frequency is like scaling the noise. Higher frequencies decrease the scale of the noise so you can see the pattern more often. Lower frequencies increase the scale of the noise so the pattern repeats less often.

You can change noise frequency using the Frequency fields. The fields let you enter numerical values to adjust the noise frequency along the X, Y or Z axis. You can also adjust the values using the scroll arrows. The number of dimensions in the noise determines how many axes you can use to adjust the frequency. For 1D noise you can only use the X axis. With 2D noise you can use both the X and Y axes. For 3D noise you can use all the axes. If you try to adjust the Z axis frequency for a 2D noise, your changes will have no effect.

Adjusting the frequency can radically change the look of your noise. If you adjust the frequency in separate axes, you can achieve even more interesting effects. This example shows frequency settings of 10 (left), 50 (middle), and 100 (right).

In this example, the noise frequency was changed in only the Y axis (X=10, Y=80, Z=10).

To change the frequency of noise:

1. Display the Deep Texture Editor.
2. Display the Noise Editor.
3. Click one of the Dimension buttons at the bottom of the editor.
   
   
4. Drag over the X field in the Frequency area to set the noise frequency in the X axis. Drag left to decrease the value or right to increase it.
   
   
5. Drag over the Y field in the Frequency area to set the noise frequency in the Y axis.
   
   
6. Drag over the Z field in the Frequency area to set the noise frequency in the Z axis.
   
   

You can also drag over the scroll arrows to speed up the increments.
