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

lighting error when night

light shining from underneath terrain/other objects that should be blocking the light?

Change day_time while running

Is there any way to change while the day_time while debugging / running the project. Because if you change the value "Day Time" in Main it will be overwrited after one frame.

By the way. I really like your shader. All the features and the beautiful athmosphere.

Shadows

Faced with the problem that the shadows are not displayed.

I was trying to implement a simple sun clock.

The shadows enabled but light energy is turns to 0 when I run the AnimationPlayer, I also was trying to run with 1 - shadows also not works

Here DirectionalLight3D with shadows enabled
