List of shader effects and sources that I used:
💡 Sun - Screen Space God rays (expensive, and needs Forward+): https://godotshaders.com/shader/screen-space-god-rays-godot-4-3/
💡 Earth/Venus Atmosphere Shader: https://github.com/Zylann/godot_atmosphere_shader
💡 Earth Day/Night/Clouds Shader with Specular map: https://github.com/LesusX/YouTube/tree/main/Rotating_Earth
💡Saturn Rings - All standard built in Godot capability. 2 sets of rings geometry. One is using TRANSPARENCY_ALPHA, but does not cast shadows. This allows semi-transparent rings that allow sunlight to come threw. Second copy of rings is rendering SHADOW_CASTING_SETTING_SHADOWS_ONLY, and using TRANSPARENCY_ALPHA_SCISSOR to cast shadows on Saturn,
Note have not tried using custom shadow shaders that is available in Godot 4.5 yet: https://github.com/godotengine/godot-proposals/issues/4443 implemented in: https://github.com/godotengine/godot/pull/93142
