Adjust this filter using the parameter controls in the Filters Inspector:

  • Softness: Sets the amount of softness applied to the refracted edges.

  • Refraction: Sets the amount that the image is distorted.

  • Height Map: Displays a thumbnail of the height map chosen. The height map is used to determine the edges along which the image is refracted.

  • Map Channel: Sets the channel used to determine how the image is refracted. If a height map is present, the channel is selected from the height map; otherwise the channel is selected from the source object. Values can be selected from the following: Luminance (default), Red, Green, Blue, or Alpha.

  • Mix: Sets the percentage of the original image to be blended with the distorted image.
