Shader Type: Lens
Output: Color (RGB) value
In the real world, camera lenses are not perfect, and therefore introduce errors (aberrations) in the images they capture. One of the most noticeable errors, called distortion, causes the resulting image to be pulled in or pushed out, so that long straight lines become bowed.
The Distortion shader applies a physically accurate camera lens distortion to an image. And because this is a lens shader, you can create a severe distortion without causing the stretching problem associated with similar post-rendering effects.
|
Amount |
Controls how much the image gets distorted. Small values will cause only a slight bending and larger values will cause greater bending. 
|
|
Pin Cushion |
Pulls the distortion inward. |
|
Barrel (Wide Angle Lens) |
Pushes the distortion outward. Barrel is the type of distortion most commonly associated with wide angle camera lenses. |
This shader can be applied directly to the camera in the lens shader stack. See Adding Lens Shaders to the Camera [Lights and Cameras].
