Shaders: Ambient Occlusion

Node Interface

Example Output

This is the same scene with no AO on the left and full AO on the right.

Overview

Function	Implements ambient occlusion in a material
Nearest C4D equivalent	Simple material with ambient occlusion effect added

This node adds ambient occlusion to the material. You can see the effect in the above example. AO makes the render look much more realistic than a plain render without AO.

Settings

Note: a * symbol next to the name indicates the parameter also has an input port. A # symbol indicates that the parameter can only be changed with an input node, not in the node itself.

Color *

The shader will colour the surface with this colour (or bitmap) which will get progressively darker in areas of maximum AO.

Output

AO

A shader output you can link directly to the Surface input of an Output node, or mix with other shaders using a Mix shader. If you use the same colour (or bitmap) in the AO shader as in the shader you are mixing it with, the Fac input of the Mix shader controls the amount of AO you see in the scene.
