Method

Add a screen space ambient occlusion (SSAO) node to the scene, this will produce subtle ambient occlusion shadows, to ground objects to surfaces and to add depth to geometry details.

Example
Nodegraph Example

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the x-axis.
Rotation Pitch Rotate the object about the y-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Shader Ability to over-ride internal shader. See writing custom shaders.
Blur Size Size of the blur from the ambient occlusion.
Max Ray Distance The maximum distance between surfaces that SSAO will be visible.
Z Bias Increasing Z bias will improve the accuracy of grounding objects to other surfaces
Blend Amount Decreasing blend amount will
Apply Mode How the Ambient Occlusion is applied to the scene.
  • Lighting * Ambient, Multiply the ambient occlusion lighting values by the colour values of the scene.
  • Ambient Only, Multiply the ambient occlusion lighting values by the ambient occlusion in the scene.
  • Lighting Only, Multiply the ambient occlusion lighting values by the lighting of the scene.
Samples The number of samples to produce the SSAO.
Animate Noise A simple noise animation on the SSAO

Inputs

Name Description Typical Node Input
Objects Add objects that are affected by the ambient occlusion. 3D Object.
