Chromatic Aberration

Chromatic Aberration is the effect of a defective lens where it fails to focus all colors into a single point. As cameras might show this in real life, in computer graphics this effect needs to be simulated to achieve a photo realistic look.

What happens inside the Lens can be illustrated like this:

In computer graphics, this effect is simulated to achieve an effect as if your graphic is filmed through a real camera.

Chromatic Aberration is built in as a post process effect in the Viz Engine Render Pipeline.

  • Make sure you are using the Viz Engine Render Pipeline and Post Process Effects are turned on in your Scene Editor.

  • Switch to Scene settings and turn on Chromatic Aberration in Post Processing.

X and Y define the offset added to single RGB channels. The higher these values are, the more distorted the lens. Typical values are around 1-2, anything else looks unrealistic.
