A specular highlight is a reflection of a light source. The position of the specular highlight depends on the position and number of light sources surrounding a surface and the angle of the camera.

Use the Shine field to change the intensity of the specular highlight. When the Shine value is set to 0, the specular highlight is disabled. To change the size of the specular highlight, use the Falloff field in the Light menu.

By default, the specular highlight is the same colour as the light source. You can change the colour of the specular highlight by changing the specular colour values.

The specular colour is the colour of light that is reflected by the surface. For example, if the specular colour is red and the light source is white, the specular highlight is red. If the specular colour is yellow and the light source is red, the highlight is orange.

To adjust specular highlights:

1. Add and position a light source in the scene.
2. In the Light menu or the Rendering section of the Action Setup menu, enable Shading.
3. In the Surface menu, use the Specular Highlight fields to set the specular colour.
4. Set a value in the Shine field. A small Shine value produces an intense highlight while a large Shine value produces a dim highlight.
