====== Skin Texture Property: outline.emissivity ======

Defines the outline emission color.
|Excepted Data Source|3 component color|
|Data Range|0 to 1 for all color components|
|Default Value|(0, 0, 0)|
|Affected Modules|Graphic|
|Linked Properties|[[gamedev:textureproperties:outline_emissivity_intensity|outline.emissivity.intensity]]|

====== Description ======

The **outline.emissivity** texture property defines the outline emission color. If outline.thickness is larger than 0 an outline is rendered around the component. This is typically used to highlight objects or to use cartoon style effects.

While [[outline_color|outline.color]] is affected by lighting outline.emissivity is not. This allows to make glowing outlines. If you use this texture property you have to also use [[outline_emimssivity_intensity|outline.emissivity.intensity]] otherwise you will get no visible emissivity.

There is no need to disable dynamically emitted light by switching materials or using **[[gamedev:renderables|renderables]]** using the Drag[en]gine. The **[[gamedev:pbr|Physically Based Rendering]]** uses high defninition range rendering. If your emitted light has an intensity of 1 or less while the object stands in the sun with over 10 intensity all around the emitted light is not going to contribute much to the illumination of the scene which is consistent with the real world. If your materials shines at night just add an emissivity texture and forget about the rest. It will just work.

The outline.emissivity value is a 3 components color value with the value of all components located inside the range from 0 to 1. 0 represents 0% light reflectivity for a color component while 1 represents a 100% light reflectivity.

The default value for this texture property is black (0, 0, 0).
