| The **emissivity.intensity** texture property is linked with the **[[gamedev:textureproperties:emissivity|emissivity]]** texture property. It defines the intensity of the emitted light. The **[[gamedev:textureproperties:emissivity|emissivity]]** texture property defines the color of the emitted light. The final emitted color is thus the **[[gamedev:textureproperties:emissivity|emissivity]]** texture property mulitplied component wise with this texture property. The intensity could also be stored directly into the **[[gamedev:textureproperties:emissivity|emissivity]]** texture property using a high definition range image. Using this texture property though the intensity can be modified at run-time using **[[gamedev:renderables|renderables]]**. Switching emitting light on and off without changing the skin on an object is a typical use of this texture property. | The **emissivity.intensity** texture property is linked with the **[[gamedev:textureproperties:emissivity|emissivity]]** texture property.

The red light is set to a bright intensity keeping up with the sunny day light. The yellow light in the middle is set to 0 intensity literally switching it off. And the green light is set to a low intensity resulting in a bareily visible green light against the sun light to show the dimmed light case. All this can be dynamically modified without switching materials.</WRAP> | <WRAP centeralign>Traffic light with 3 different **emissivity.intensity** **[[gamedev:renderables|renderables]]** set to different values.
