Nebula Generator is a volumetric material setup for creating 3D space environments in Blender. Controlled primarily through a custom node in the Shader Editor, it allows users to customize the structure, color, and density of nebulae for cinematic animations or custom HDRI skyboxes.

The included project file comes ready to render in Cycles. It features pre-configured camera perspectives, a customizable star background built in the World Editor, and compositor nodes set up for glow and glare effects. While optimized for Cycles, the core material can be adapted for EEVEE with minor adjustments.
