A simple Godot 4 project with day-night and season systems, a procedurally moving sun and moon, and a stylized sky shader.
Features:
- Extremely simplified day-night system with support for seasons based on latitude and earth axial tilt
- Calculated position of the sun and drawing it through the sky shader
- Shorter days in winter and longer in summer
- Changing position of the sun depends of the day of the year
- Calculated position of the moon and drawing it through the sky shader
- Include the inclination of the orbit and the period of time to cover it
- Sky shader
- Clouds based on noise function (without repeating texture)
- Phases of the moon depending on the position of the sun
