This section contains settings related to screen-space global illumination (SSGI).
| Enabled |
Toggles SSGI on and off. It enables indirect illumination in the scene. |
| Intensity |
Brightness of illumination:
- By the minimum value of 0, the illumination is the darkest.
- By the maximum value of 1, the illumination is the brightest.
Intensity = 0.2
|
Intensity = 1
|
|
| Quality |
Quality (number of the used samples) of the screen-space global illumination:
- Low — 4 samples
- Medium — 8 samples
- High — 16 samples
- Ultra — 32 samples
Quality = Low
|
Quality = Ultra
|
|
| Resolution |
Resolution used for the screen-space global illumination:
- Quarter — quarter resolution
- Half — half resolution
- Full — full resolution
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:
- By low values, each point affects only the points in the close range.
- By high values, each point affects farther positioned points.
Radius = 0.5
|
Radius = 1
|
|
| Normal Threshold |
Determines sensitivity of GI to normals. Normals affect ray intensity: smaller angle of incidence increases ray intensity.
- By the minimum value of 0, normals are ignored.
- By the maximum value of 1, normals are taken into account.
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). |
