Pro-Lighting: Skies is an outdoor lighting add-on for Blender, developed by Blender Guru. It offers one-click outdoor lighting with HDR-quality output optimized for Blender, aiming for results that are accurate to the real world. It is an all-in-one solution for lighting outdoor scenes.
Where a single sun lamp represents one light source, this add-on works with HDR-based lighting to fill a scene with a full dome of illumination. That approach keeps the lighting realistic and grounded in real-world reference, so the focus can stay on the artwork.
Version 1.4.3 is fully compatible with Blender 5.0, and documentation is included. A demo video is available, and the add-on ranks 41 in the superhive library. It is listed here as free, so check the developer's page for current licensing details.
