====== Skin Texture Property: refraction.distort.strength ======

Defines the strength of the refraction distort effect.

|Excepted Data Source|1 component value|
|Data Range|any value|
|Default Value|0.01|
|Affected Modules|Graphic|
|Linked Properties|[[gamedev:textureproperties:refraction_distort|refraction.distort]]|

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

The **refraction.distort.strength** texture property is linked to the **[[gamedev:textureproperties:refraction_distort|refraction.distort]]** texture property. It defines the strength of the refraction distortion. The displacement is measured relative to the size of the render window.

The source is typically a single component value representing the displacement percentage relative to the render window. 0.1 for example would be a maximum displacement of 10% of the render window width. Negative values are possible to invert the effect.

The default value for this texture property is 0.01 (1% of render window).

====== Examples ======

{{ :gamedev:textureproperties:refraction_distort.png |Distorted refraction behind a transparent object}}
<WRAP centeralign>Distorted refraction behind a transparent object. The distortion is not a true Fresnel based refraction but a Screen Space distortion. Using the **[[gamedev:textureproperties:refraction_distort_strength|refraction.distort.strength]]** texture property the strength of the distortion can be controlled. As image a normal map is used which allows to reuse the normal map also for distortion effects.</WRAP>
