• ⚠️ Important Upgrade Notice: Due to the new package format, any previous installations of this asset must be deleted before upgrading to avoid conflicts.

🌌 Procedural Nebula Patterns

Create colorful, dynamic cosmic skyboxes with this modular procedural shader built with Shader Graph. Bring your artistic vision to life with infinite cosmic backgrounds generated by modern procedural pattern generation techniques.

🧩 Asset Contents

Procedural Space Skybox - a procedural shader built with Shader Graph with the following subgraph modules:

• ☀️Sun: Procedural sun effect linked to the main directional light in the scene.
• ✨Background Starfield: Densely packed stars with randomized colors and sizes.
• 🌟Glowing Stars: Larger stars with spherical glow effects.
• 🌌Galactic Band: A detailed Milky Way-like structure divided into outer glow, disk, and rift regions.
• 🌫️Nebulas: Customizable vibrant nebula patterns generated by domain-warped noise.

🎨 Modular Shader Components

Various visual effects organized in neat subgraphs and HLSL functions for easy customization:

• HLSL modules
• Shader Graph Sub Graphs

If you're looking to extend this shader or build entirely new procedural shaders, use these building blocks to kickstart your development.

🛠️ Performance

This shader can be used as a dynamic skybox at runtime, with the following performance when using all modules on an NVIDIA GTX 3060 GPU(performance can be increased by disabling modules or rendering a static skybox):

• 82 FPS average at 1080p
• 25 FPS average at 2160p

⚡ Static Skybox Rendering

For optimal performance, an included editor utility allows you to capture and render procedural skyboxes into static cubemap textures. This process significantly improves runtime performance:

• 500+ FPS average with static cubemaps.
• Maintain the visual fidelity of the dynamic procedural skybox while reducing GPU load.
• Keep the dynamic procedural sun effect with the custom Cubemap Skybox with Procedural Sun shader.

URP and BRP compatible

This package can be used with both the Built-in Render Pipeline and Universal Render Pipeline. It does not support the High Definition Render Pipeline.
