Nebula HDRI and Skybox Generator is a ready-to-use project file designed for creating volumetric space backgrounds in Blender. The system is built around a customizable volumetric shader setup that allows users to adjust the appearance of the nebula directly within the Shader Editor.

Optimized primarily for Cycles, the project is configured by default to render HDRI backgrounds and skyboxes. While tailored for Cycles, it can be adapted to work with EEVEE with some material adjustments. The rendered outputs can be exported as standard image sequences or video files for use in external applications like game engines and compositors.
