Example 1: Direction of the VRaySun light

This example demonstrates the effect of the sun direction. Note how in addition to the scene brightness, the sun position also changes the appearance of the sky and the sun light color.

 

Enabled: on, Turbidity: 3.0, Shadow subdivision: 8, Intensity multiplier: 0.01, Size multiplier: 1.0

 

Sun Z height: 500
Sun Z height: 1600
Sun Z height: 6000 (almost straight above)

Example 2: The Size multiplier parameter

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).

 

Enabled: on, Turbidity: 3.0, Shadow subdivision: 8, Intensity multiplier: 0.01

 

Size multiplier is 4.0
Size multiplier is 10.0
Size multiplier is 40.0

Example 3: The Shadow subdivs parameter

This example demonstrates the effect of the Shadow subdivs parameter. Note how lower subdivs cause the shadows to be more noisy.

 

Enabled: on, Height Z: 1200, Turbidity is 2.0, Intensity multiplier is 0.01, Size multiplier: 10.0

 

Shadow subdivs is 8
Shadow subdivs is 16
Shadow subdivs is 48

Example 4: The Turbidity parameter

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, Shadow subdivision: 8, Size multiplier: 1.0

 

Turbidity is 2.0
Turbidity is 4.0
Turbidity is 8.0

Example 5: The Intensity multiplier parameter

Enabled: on, Turbidity: 3.0, Shadow subdivision: 8, Size multiplier: 1.0

 

Height: Z = 0, Intensity mult: 0.01
Height: Z = 0, Intensity mult: 0.03
Height: Z = 0, Intensity mult: 0.05
Height: Z = 500, Intensity mult: 0.01
Height: Z = 500, Intensity mult: 0.03
Height: Z = 500, Intensity mult: 0.05

Example 6: Color mapping types

In addition to the parameters of the sun and sky, their appearance also depends on the selected color mapping mode. This example demonstrates the looks achieved with several different color mapping modes. See also the section on Color mapping for more details.

 

Enabled: on, Height Z: 800,Turbidity: 3.0, Shadow subdivision: 8, Intensity multiplier: 0.01, Size multiplier: 1.0

 

Color mapping: Linear
Color mapping: Exponential
Color mapping: HSV exponential
Color mapping: Intensity exponential

Example 7: Ozone value

The Ozone parameter affects only the color of the light emitted by the sun. Higher values color mapping mode. This example demonstrates the looks achieved with several different color mapping modes. See also the section on Color mapping for more details.

 

Enabled: on, Turbidity: 2.0, Shadow subdivision: 36, Intensity multiplier: 0.01, Size multiplier: 10.0

Ozone: 0.0
Ozone: 0.5
Ozone: 1.0

Example 8: Shadow bias

Enabled: on, Turbidity: 2.0, Shadow subdivision: 36, Intensity multiplier: 0.01, Size multiplier: 10.0

Shadow bias: 0.0
Shadow bias: 7.0
Shadow bias: 13.0
