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

Defines the outline emission color.
|Excepted Data Source|1 component value|
|Data Range|0 or larger|
|Default Value|0|

|Linked Properties|[[gamedev:textureproperties:outline_emissivity|outline.emissivity]]|

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

The **outline.emissivity.intensity** texture property defines the outline emissivity intensity. If [[outline_thickness|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.

The intensity value relates to real world light intensities not in a 1-to-1 scale but more in a rescale scale mapping a wel lit room to the value 1 for convenience. An intensity value of 1 thus equals roughly a 100W light bulb or a well lit room at night. 10 equals roughly an overcast day outside. 20 equals roughly a full bright sunny day out in plain sun.

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 1 component value inside the range of 0 or larger.

The default value for this texture property is 0 intensity.
