SSGI

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

Global Illumination Settings

Screen-Space Global Illumination Settings

Enabled

Toggles SSGI on and off. It enables indirect illumination in the scene.

Intensity

Brightness of illumination:

Intensity = 0.2

Intensity = 1

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

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

Limits ray-traced SSGI in areas where SSRTGI cannot get information.

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