About Light Helper

Light Helper is a Blender add-on designed to simplify light exclusion workflows. It offers two linking modes: Light Link, which defines which object or collection a light should illuminate, and Object Link, which specifies which lights affect a given object. Both modes handle lighting and shadows. The add-on automatically detects lights attached to objects and materials whose Emission channel intensity exceeds zero, eliminating manual tagging. Users can create exclusions for lights and materials, and even exclude a light together with its illuminated objects. For scenes with many lights, Light Helper provides quick selection tools to rapidly choose linked objects or the lights that reference them. It requires no special permissions, runs on Blender 4.2 LTS and newer, and is distributed under the GNU General Public License v3.0 or later.
