Using Ambient Occlusion

Ambient Occlusion is a shading method in iClone which helps add realism to models and scenes. It enhances edge shadows by simulating the attenuation of light due to occlusion. Ambient Occlusion simply attempts to approximate the way light radiates in real life, especially off what are normally considered non-reflective surfaces.

Enabling Ambient Occlusion

1. Switch to the Atmosphere tab on the Visual Settings panel.
2. In the Ambient Occlusion section, enable the Ambient Occlusion box.
   

   Rendering State: Smooth
   Ambient Occlusion = Off	Ambient Occlusion = On
   Rendering State: Normal
   Ambient Occlusion = Off	Ambient Occlusion = On

Modifying Ambient Occlusion

• The Strength decides the darkness of the Ambient Occlusion.
• The Range decides the spread of the ambient shadow from the creases on the objects.

  Ambient Occlusion: Off	Strength = 30 Range = 15
  Strength = 100 Range = 15	Strength = 100 Range = 50 (the spatial feeling is diminished)

• When you decide the Strength and the Range values, you may also use the Distance value to increase or decrease the effect of the Ambient Occlusion effect.

  Distance = 1	Distance = 3
