Glare is an add-on that automates post-processing effects in Blender by adding a customizable node setup to the compositor. It provides real-time viewport and render effects for both Cycles and EEVEE. Users can apply the effect with a single click without manually opening the Compositor, while still retaining the ability to insert custom nodes into the chain.

The tool includes controls for bloom, lens artifacts, streaks, chromatic aberration, and volumetric-style light rays. It also features overlays like shimmer, fog, and custom textures such as lens dirt or scratches. A dedicated render pass feature automates the creation of transparent passes for further adjustments in external post-processing software.
