Pure-Sky Pro is a sky and atmosphere system for Blender developed by 3DVision, built for creating skies, realistic clouds, and lighting environments across cinematic animations, photorealistic renders, and stylized scenes. It carries an extensive preset library: 21 sky presets spanning sunrise to midday to starry nights, 22 cloud presets, and 6 atmospheric fog presets. Custom sky, cloud, and fog presets can be exported and shared.
Clouds come in authentic types including Fluffy Cumulus, Majestic Cumulonimbus, and Delicate Altocumulus, and they grow naturally into evolving formations. A set of modes extends the workflow: Hybrid Mode blends procedural skies with HDRI maps, Collision Mode simulates physical interactions with clouds, Join Mode turns any mesh into a cloud cell, and Edit Mode lets you sculpt clouds in real time. Cloud Mask controls placement, while Ground Fog adds low-lying atmosphere.
Pure-Sky Pro is compatible with Blender's Eevee Next and Cycles render engines and integrates with the Sun Position add-on for physically-accurate lighting. It suits both still renders and animations, with highly customizable parameters and an intuitive interface. A demo video is available.
