Env Lights Design is a Blender add-on that brings Light Sets, cameras, atmosphere and rendering into one connected Cycles workflow. It lives in the 3D Viewport sidebar, opened with the N key, under a Lights Design tab.
A Light Set shapes sky, sun, clouds, fog and tone as a single look. You can build a sky or connect an environment image through HDRI, drive sun direction from coordinates, date and hour, and layer clouds, fog, god rays and tone in the same panel. Camera assignment keeps every view paired with its intended environment, and Light Sets can be imported and exported between scenes as JSON.
The render queue closes the loop: queue cameras for stills, run animation, and each queued still activates its camera and assigned Light Set automatically. The current release is version 1.0.0, targeting Cycles, with builds verified against Blender 4.5.3 and 5.1.2.
