Super Simple Nebula Creator

Super Simple Nebula Creator gives you three ways to fill your space scenes with rich, procedural nebulae — each with a full custom editor, seed system, and save-able presets.

Nebula Skybox

A full 360° procedural skybox with domain-warped noise, a configurable star field, and an interactive preview you can orbit inside the editor. Click a preset, hit "Apply to Scene Skybox" and your sky is done. Customize colors, coverage, warp strength, rotation, and more. Works in any render pipeline. Zero runtime cost — it's a skybox shader.

Nebula Cloud

A particle-based nebula built for flythrough scenes. Smooth camera-proximity fading means no hard billboard edges when you fly through the cloud. World-space procedural noise makes neighboring particles share coherent density patterns, giving the cloud a continuous volumetric feel. A very performant option. Works in any render pipeline.

Nebula Volume

A raymarched volumetric cloud sphere you place anywhere in your scene. Scale the Transform to any size, from a wispy 50-unit accent to an 800-unit centerpiece. This one is resource heavy and will require good hardware. URP only.

All three types share:

• Seed-based generation — type any word or number and get a unique, fully reproducible nebula
• "New Seed" randomization button for instant inspiration
• Save-and-recall user presets per component
• Matching gizmo handles for resizing directly in the Scene view

Included:

• Demo scene with flythrough camera (WASD + right-click look)
• 2 NebulaVolume prefabs, 2 NebulaCloud prefabs
• Full Getting Started documentation
