About QLE (Quick Lighting Environment)

QLE (Quick Lighting Environment) is a free Blender add‑on from developer don1138. After installation it adds a panel called Quick Lighting Environment under Properties → Scene with two buttons: Add Environment and Clear Environment. Add Environment creates a World named “QLE World” (strength 0.25, Blackbody 5454), four area lights with preset colour temperatures, an Empty named Lights_Target that each light tracks, and a mesh Backdrop. If any of these objects or constraints are missing, clicking Add Environment restores them. Clear Environment removes the QLE lights, Empty, Backdrop, and resets the World to its original state. The add‑on requires an active World in the scene and runs on Blender 4.2 LTS and newer. It is released under the GNU GPL v3.0 or later.
