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 sunposition 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

Example 2: The Size multiplier parameter

This example demonstrates the effect of the Size multiplier parameter. Notice how changes in this parameteraffect both the visible sun size and the shadow softness (however overall illumination strength remains thesame). 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

Example 3: The Shadow subdivs parameter

This example demonstrates the effect of the Shadow subdivs parameter. Note how lower subdivs cause theshadows 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

Example 4: The Turbidity parameter

This example demonstrates the effect of the Turbidity parameter. Generally this controls the amount of dustparticles in the air. Notice how larger values cause the sun and the sky to become yellowish while smaller valuesmake 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

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

Height: Z = 500, Intensity mult: 0.01 Height: Z = 500, Intensity mult: 0.03 Height: Z = 500, Intensit

In addition to the parameters of the sun and sky, their appearance also depends on the selected color mappingmode. This example demonstrates the looks achieved with several different color mapping modes. See also thesection on Color mapping for more details. Enabled: on, Height Z: 800,Turbidity: 3.0, Shadow subdivision: 8, Intensity multiplier: 0.01, Sizemultiplier: 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 thesection 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
