### **Example: Intensity Multiplier**

Common settings in this example are **Turbidity:** 3.0, **Size Multiplier:** 1.0, **EV:** 14,48 (default).

> Macro (anchor)



### **Example: Size Multiplier**

Common settings in this example are **Turbidity:** 3.0. This example demonstrates the effect of the Size multiplier parameter. Notice how changes in this parameter affect both the visible sun size and the shadow softness (however overall illumination strength remains the same).

### **Example: PRG Clear Sky New - Altitude**

This example shows how the Altitude values affect the visualization of the sky.  Higher Altitude values result in better sky clarity and a less defined horizon line.

### **Example: PRG Clear Sky New - Turbidity**

In this example, you can see how the amount of dust in the air affects the color of the sun and sky.  Smaller values produce a clear image, while higher values dim the sun and sky.

### **Example: PRG Clear Sky New - Nautical twilight effect**

This example shows how the sun's position affects the sky, creating a twilight effect. Changing the sun's position could require adjusting the Exposure Value as well.

### **Example: Turbidity**

This example demonstrates the effect of the Turbidity parameter. Generally, this controls the amount of dust particles in the air. Notice how larger values cause the sun and the sky to become yellowish, while smaller values make the sky clear. **Enabled:** on, **Intensity multiplier:** 0.01, **Size multiplier:** 1.0

### **Example: Ozone Value**

Common settings in this example are **Turbidity:** 2.0, **Intensity Multiplier:** 0.01, **Size Multiplier:** 10.0. The Ozone parameter affects only the color of the light emitted by the sun.

### **Example: Direct Light **

The **Direct Light **parameter controls the brightness of the stars in this example.

### **Example: Moon Direct Light**

This** **parameter controls the brightness of the moon in this example.

> Macro (anchor)



### **Example: Cloud Density**

The Density parameter controls the amount of clouds in the sky. The higher the value, the more clouds appear in the render.


---

> Macro (anchor)



### **Example: Clouds Variety**

This example shows the effect of the Variety parameter on the distribution and appearance of the clouds.


---

> Macro (anchor)



### **Example: Cirrus Amount**

This example shows how increasing the Cirrus Amount increases the appearance of the cirrus clouds in the render.


---

> Macro (anchor)



### **Example: Cloud Height**

This example shows how the clouds change their position in the sky with increasing the Height value.


---

> Macro (anchor)



### **Example: Cloud Thickness**

The Thickness parameter specifies how full the clouds are. Smaller values make them thinner and sheer, while higher values make them look heavier.


---

> Macro (anchor)



### **Example: Ground Shadows**

This example shows the effect of the Ground Shadows option.



---

> Macro (anchor)



### **Example: Number of Contrails**

Note that the contrails are spread randomly across the sky. In most cases, the camera does not capture all of the contrails.


---

> Macro (anchor)



### **Example: Contrails Strength**

This example shows how the strength parameter makes the contrails more visible and prominent in the sky.


---

> Macro (anchor)



### **Example: Contrails Distortion**

The Contrails distortion parameter is used to add variety to the trace line. 


---

> Macro (anchor)



### **Example: Contrails Offset**

The Contrails offset option introduces an offset along the X or Y direction in the sky. 


---

> Macro (anchor)



### **Example: Contrails Pace**

The frames in this animation show the Contrails Pace parameter, with values ranging from 0 to 2.0, in steps of 0.2.
