Lazy Composer is an add-on that simplifies the compositing process by providing a unified interface for post-processing effects directly within the Blender viewport. It utilizes the real-time viewport compositor, allowing you to preview adjustments immediately in both Cycles and Eevee render engines.

The toolset includes options for color correction, brightness and contrast tuning, and film emulation. It also provides atmospheric and optical adjustments such as glow, glare, light rays, halation, and procedural film grain. All effects are accessible and controllable from a single dedicated tab in the user interface.
