Ambient Occlusion (AO)

The ambient occlusion map is usually something you get from a bake in Substance Painter, Blender, Marmoset etc.

It controls how indirect specular and diffuse (light volumes, light probes, reflection map) is received. The presence of occlusion indicates that the lighting model should not integrate these lighting elements into the shading of the pixel.

General Settings

AO Texture

Allows you to specify an ambient occlusion map.

• Uses UV0.
• Only the 'red' component is used.
• Defaults to white (no occlusion) when not set.

AO Strength

Controls how intense the AO texture is.

• A value of 1 will just use the AO texture raw.
• A value of 0 will disable the AO texture.
