Refract

A refracting func_brush.

The Refract shaders distorts objects behind it. It is similar to Water, but does not reflect.

Note:The shader may not work when applied to world geometry. Make any brushes you want it applied to are attached to entities (excluding func_detail).

Example

Refract
{
	$normalmap ...			// Defines the refraction pattern; may be animated
	$dudvmap ...			// As above when running below DX9
	$refracttint "[1 1 1]"		// Colors the refraction
	$refractamount 0.2		// Refraction strength; use low values
}

Tip:$refracttint values greater than one can make it brighten instead of darken.

Tip:$bluramount 1.0 // Defines how much the refraction should blur.

Tip:$refracttinttexture ... // Defines a texture map for tinting the refraction.
