Open Example Read Tutorial Download

Screen-Space Ambient Occlusion is a post-process that coarsely approximates a shadowing effect from ambient light. Its practical effect is a better perception of spatial relations between objects in. Screen-Space Ambient Occlusion can be enabled with the Environment node’s attribute “SSAO”. The attribute “SSAOamount” determines the strength of the SSAO effect. The attributes “SSAOblurDepthTreshold” and “SSAOradius” must be tweaked according to the scale of the scene.
