A new procedural sky and cloud system called Sky is now available for Blender via Superhive Market. The tool is built entirely using Blender’s Geometry Nodes and procedural shaders, allowing artists to generate and animate volumetric clouds and a full atmospheric sky directly inside Blender without relying on HDRIs or pre-rendered sky textures.
Sky is designed for use with Blender 5.0 and the Cycles render engine and focuses on physically based volumetric rendering. Both the clouds and the atmosphere are constructed at real-world scale, aiming for physically plausible light scattering and cloud behaviour rather than stylised shortcuts.
Included cloud types and artistic control
The asset includes four common cloud formations: cumulus, cumulonimbus, cirrus, and altocumulus. These cloud types can be combined and layered to build more complex sky setups and different lighting conditions, including daytime and sunset scenarios.
Because the system is procedural, users can adjust cloud size, coverage, and overall appearance, and animate these parameters over time. This makes the tool suitable for both still imagery and animated shots where cloud movement and atmospheric changes are required.
Physically based shading and volumetric rendering
According to the developer, the shaders used in Sky are based on research into air and water particle behaviour. The goal is to approximate realistic light interaction inside volumetric clouds rather than relying on simplified noise-only approaches. This makes the system computationally demanding, as expected from true volumetric rendering inside Cycles.
The product page notes that volumetric rendering performance depends heavily on hardware. A system with at least 16 GB of memory is recommended. As a reference example, a 720p render at 128 samples using an Nvidia RTX 4090 with Optix acceleration takes roughly six minutes.
Availability and pricing
Sky is available via Superhive Market and is sold under a royalty-free licence. At the time of writing, the tool is priced at 25 US dollars and is positioned as a ready-to-use Geometry Nodes setup for artists who want procedural skies and volumetric clouds without building their own node systems from scratch.
