Noise Orientation

Noise Orientation controls the direction of the noise. When you adjust the noise orientation, you change how the noise is laid out within the texture. When you apply a texture, the direction of the noise within the texture remains constant regardless of the orientation of the object. Since noise can exist in three dimensions, you adjust the direction of the noise in the X, Y, or Z axis. This example shows rotation in X (left), XY (middle), and XYZ (right).

The number of dimensions in the noise determines how many axes you can use to adjust the orientation. 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.

You can edit the noise orientation using the Direction numerical fields. The fields let you enter precise angles for noise orientation. You can also use the scroll arrows to set the angle in increments. Changing noise orientation can dramatically change the look of your noise. You'll see just how different your noise can look when you rotate it along a single axis.

To change the orientation 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 XY field in the Direction area to set the noise angle in the X and Y axes. Drag left to decrease the value or right to increase it.
   
   
5. Drag over the YZ field in the Direction area to set the noise angle in the Y and Z axes.
   
   

You can also drag over the scroll arrows to speed up the increase/decrease or click on the arrows to increment the values by one number at a time.
