ClearSky provides a procedural sky generation system for Blender using a customized node group. The setup integrates directly into the World environment, allowing users to configure atmospheric lighting and sky appearance within the shader editor.

The package includes the primary sky generation node group, alongside three additional node groups designed to complement the sky system. These include a procedural reflective ocean setup and two tools for controlling sun direction. The system is fully compatible with both the EEVEE and Cycles render engines.
