Unity 2021.3
Super Simple Skybox is a fast, lightweight skybox asset that uses Shader Graph. Configure your sky colors to nail down the exact look you’re going for. Use procedural stars and night sky texture blending to create realistic or stylized night skies. Render fast, simple clouds that look good. Add a sun and a moon, position them, then let the time of day system do the rest. Setup is easy with one material to apply to your environment.
