I made a space skybox shader using Amplify shader editor. I have exposed a bunch of the parameters to the inspector so it’s modifiable without going into the source. The sun on the skybox matches the direction and color of the directional light in the scene like the standard skybox in unity does.
The source is available for download, it’s originally made with Amplify shader editor but you don’t need it to use the shader.
Disclaimer: The shader is completely untested in any production environment.
