SSAO

This tab contains settings related to screen-space ambient occlusion (SSAO).

Ambient Occlusion Settings

Notice

The settings of the screen-space ambient occlusion can be adjusted if the Occlusion is enabled on the System menu -> Render panel.

Intensity	Brightness of shadows: By the minimum value of 0, the ambient occlusion shadowing is the lightest. By the maximum value of 1, the ambient occlusion shadowing is the darkest.
Intensity lighted side	Intensity of the lighted side.
Intensity reflection	Intensity of SSAO on reflections.
Cavity	Enables or disables the cavity option for the SSAO (Screen Space Ambient Occlusion) effect. This option improves (sharpens) the look of junction contours at low resolutions, so it should be used for detail enhancement (small stones, bolts and so on).
Cavity intensity	Intensity of sharpening of contours for the cavity option.
Cavity radius	Size of junction contours area for the cavity option.
Ray tracing	Enables or disables ray tracing for SSAO calculation. When enabled, SSAO provides more realistic shadows between the objects. Notice Ray-traced SSAO calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).
Ray tracing denoise	Enables or disables noise reduction for the ray-traced SSAO. This option reduces noise by using blur effect. Notice Ray-traced SSAO calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).
Ray tracing threshold	Sets the threshold value for the ray-traced SSAO. Notice Ray-traced SSAO calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).
Quality	Quality (number of the used samples) of the screen-space ambient occlusion: Low — 4 samples Medium — 8 samples High — 16 samples Ultra — 32 samples
Resolution	Resolution used for the screen-space ambient occlusion: Half — half resolution Full — full resolution
Noise	Enables screen-space ambient occlusion noise Notice We recommend to use it with TAA enabled.
Radius	Distance for each of the points in the world space, up to which they can cast shadows on their neighboring points: By low values, each point can shadow only the points in the close range. By high values, each point shadows farther positioned points.
