Chromatic Aberration Master Node is a custom node group for Blender's Compositor that expands upon the built-in Lens Distortion node. It provides granular control over post-processing chromatic aberration effects, allowing artists to adjust specific parameters that are usually locked in the default compositing tools.

The node group supports specific color channel separations, including Red/Cyan, Green/Magenta, and Blue/Yellow chromatic aberration. It features translate and scale functions for positioning the effect, high-resolution and low-resolution calculation outputs for performance management, and fully animatable values for motion sequences.
