Nebula Forge

Volumetric Rendering – Create fully three-dimensional nebulae with real depth using optimized ray marching. Fly through vast cosmic structures instead of relying on flat billboard effects. Volumetric Lighting & Streaking Shadows – Add a pulsing star to the center of your nebula, and have cometary knots that cast realistic, outward-streaking shadows. Multi-Layered Detail – Design intricate formations from soft wisps to dense, complex clusters. Blend multiple layers of detail to give your nebulae a natural, highly structured appearance. Vivid Coloring – Achieve vibrant color transitions that respond naturally to density and emission, avoiding artificial, banded gradients. High Performance – Built for speed. Delivers impressive visual fidelity through highly optimized ray marching and Temporal Anti-Aliasing support, remaining efficient for real-time applications. It can even pause updating if your camera movements relative to the nebula are minimal. Endless Variations – Generate endless nebula variations with the click of a button, or manually tweak each and every setting, giving you full creative freedom. Subtle Animation – Add life to your scenes with gentle star pulses and evolving colors that keep the nebula feeling dynamic and alive. 26 Ready-To-Use Demo Scenes – Get up and running quickly with a diverse collection of pre-built scenes, showcasing different styles and setups you can learn from or use directly. Seamless Scene Integration – Easily incorporate the nebula system into your existing environments, working smoothly alongside planets, backgrounds, and other visual elements. Full Source Code Included – If you're a programmer, feel free to tweak the code as much as you like. It's clean, accessible, and designed to be easy to modify.
