SSGI

This tab contains settings related to screen-space global illumination (SSGI).

Global Illumination Settings

Notice

Screen-space global illumination (SSGI) should be enabled via the Rendering mode panel (Rendering - > Features - > SSGI).

Intensity

Intensity of SSGI:

Intensity = 0.2

Intensity = 1

Ray tracing

Enables or disables ray tracing for SSGI calculation. When enabled, SSGI recreates light reflections from the object’s surface.

NoticeRay-traced SSGI calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).

Ray tracing denoise

Enables or disables noise reduction for the ray-traced SSGI. This option reduces noise by using blur effect.

NoticeRay-traced SSGI calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).

Ray tracing threshold

Sets the threshold value for the ray-traced SSGI.

NoticeRay-traced SSGI calculation available only when the SSRTGI technique is enabled (Rendering -> Features -> SSRTGI).

Quality

Quality (number of the used samples) of the screen-space global illumination:

Quality = Low

Quality = Ultra

Resolution

Resolution used for the screen-space global illumination:

Resolution = Quarter

Resolution = Full

Resolution color

Resolution of the color buffer used for screen-space global illumination.

Radius

Determines the size of the region surrounding a particular sampling point:

Radius = 0.5

Radius = 1

Normal threshold

Determines sensitivity of GI to normals. Normals affect ray intensity: smaller angle of incidence increases ray intensity.

Normal threshold = 0

Normal threshold = 1
