Edits In Progress, Highly Unfinished Page
Valve's Source engine uses SSAO which stands for Screen Space Ambient Occlusion.
What Visual Difference Ambient Occlusion Makes
Enabling Ambient Occlusion
Enabling Ambient Occlusion is as easy as right-clicking the viewport and heading to your render settings. In the dialog box for your render settings, check the box adjacent from the Ambient Occlusion setting which reads "enable". Make sure that the drop-down menu next to the AO setting reads "AO Only" and not "Outline(link) Only" or "AO & Outline" (edit for proof, add pictures).
Note:If there's ugly black speckles frequenting the scene upon enabling AO, that is normal. All this means is that you are not looking through your scene camera with at least 8 samples of depth of field rendered in the viewport (you must be in the Clip Editor).-Comparison picture: No DoF versus DoF at varying sample rates
Camera Settings
SSAO Bias: Determines the threshold for visible ambient occlusion
SSAO Strength: Determines the intensity of the shadows cast by ambient occlusion
SSAO Radius: Determines the filtersize (spread) of shadows cast by ambient occlusion
Tip:In almost all situations, you will find that increasing your bias while restricting your radius will produce the most realistic ambient occlusion. In order to refine your AO to a precise level, go into your viewport render settings and check "Show AO". Your viewport will only show your ambient occlusion shading and you'll be able to know exactly where it's affecting your models.
