Procedural Nebula
A stylized galaxy/space background generated entirely with procedural nodes in Blender. The World shader layers nebula clouds and star fields using noise- and Voronoi-based patterns, shaped through Map Range/ColorRamp controls and combined with Lighten blending for art-directable density and contrast.
The final look is refined in the Compositor with cinematic post effects, including streak and bloom glare, chromatic aberration (lens dispersion), tonal tuning, and RGB curve shaping. Rendered in Cycles with GPU acceleration and Filmic high-contrast color management.
Key techniques
- Procedural World shader: Noise/Voronoi + Map Range/ColorRamp masking
- Layered blending: Lighten + intensity boosting (Add)
- Coordinate control: Texture Coordinate + Mapping
- Post-processing: Glare (streaks/bloom), chromatic aberration, tone tuning, RGB curves
