This is helpful for creating an either more intense or ligher specular with the map settings. *** ## ADJUSTING THE MAP You can use the Gamma, Contrast, Brightness, and Input and Output Level settings to adjust the brightness to either darken or lighten an image.

### Invert Check the **Invert** box to flip the color values to the opposite values.

### Opacity and Saturation **Opacity** will control how much the map will affect that Texture Channel. Lowering the **Saturation** will bring the color closer to black and white.

*** ## UV Repeat and Offset Adjust how many times the texture repeats with **UV Repeat** and adjust the positon along the surface with **UV Offset**.

### Drop Down Wing In addition to being able to drop textures into the slot, you can also **Load From File**. You can also choose **Custom Layers** from AE to set as the texture, see Using Videos as textures for more info.
