Sky

Sky is divided into Physics Sky and HDRI Sky.

TIP

• The various properties of the sky are quite complex, and it is difficult to accurately describe the function of each property in words.
• It is recommended to experiment hands-on, adjusting each property yourself to understand its function and effect.
• Here, only the properties, their types, and default values are listed, without extensive explanation.
• If you want to simulate Earth's sky, you can keep the default settings for this component.
