The **refraction.distort** texture property defines the distortion to use for objects rendered behind a transparent object. Distortion effects are typically screen space effects simulating refraction distortion happening behind transparent materials with curvy and bumpy surface. Using full fresnel refraction calculations is usually not feasible in real time. This effect can though still be faked in screen space an image defining at what offset to use an image from behind the object. This technique has its limitations but it produces reasonable results fast. | The **refraction.distort** texture property defines the distortion to use for objects rendered behind a transparent object.
