SSGI
This section contains settings related to Screen-Space Global Illumination (SSGI).
| Enabled |
The value indicating if the SSGI (Screen Space Global Illumination) effect is enabled. Enabled by default.
Console access: render_ssgi |
|---|---|
| Preset |
The currently used SSGI (Screen-Space Global Illumination) preset. The following presets are available:
Console access: render_ssgi_preset |
Notice
Presets override user-defined custom settings. When any preset other than Custom is active, modification of the parameters via API has no effect. The parameter value set via the last API call shall be used only when the Custom preset is active. When checking the current parameter value via API you'll get the corresponding setting stored in the active preset (default or custom one).
Customizable Settings#
The following settings are available when the Custom preset is selected.
Screen-Space Global Illumination Settings
| Intensity |
The intensity of the SSGI (Screen Space Global Illumination) for the scene. By the minimum value of 0.0f, the global illumination is the darkest. Range of values: [0.0f, 1.0f]. The default value is 1.0f. Console access: render_ssgi_intensity
|
||
|---|---|---|---|
| Intensity Boost |
The boost intensity value. Increases the SSGI intensity by raising the value to the specified power. One of the following values:
Console access: render_ssgi_intensity_boost |
||
| Color Clamping Intensity |
The intensity of TAA color clamping at zero pixel velocity for the SSGI (Screen Space Global Illumination) effect. Lower values result in more accumulated frames combined, which reduces noise flickering, but increases ghosting effect (to reduce ghosting in this case you can use SSGI Color Clamping Velocity Threshold, while higher values reduce ghosting effect, but increase flickering. Range of values: [0.0f, 1.0f]. The default value is 1.0f. Console access: render_ssgi_color_clamping_intensity |
||
| Color Clamping Velocity |
The sensitivity of TAA color clamping for the SSGI (Screen Space Global Illumination) effect to pixel velocity change. This parameter is used to reduce ghosting effect for lower Color Clamping Intensity values: it automatically increases clamping intensity for higher velocities, and disables clamping for low velocity values. Range of values: [0.0f, inf]. The default value is 0.0f. Console access: render_ssgi_color_clamping_velocity_threshold |
||
| Threshold |
The threshold value for the ray-traced SSGI (Screen Space Global Illumination).
Notice
Ray-traced SSGI calculation available only when the SSRTGI technique is enabled. Range of values: [0.0f, inf]. The default value is 1.0f. Console access: render_ssgi_threshold |
Denoise Options#
| Denoise |
The value indicating if noise reduction for the ray-traced SSGI (Screen Space Global Illumination) is enabled. This option reduces noise by using blur effect. SSRTGI technique must be enabled. Enabled by default.
Console access: render_ssgi_denoise |
|---|---|
| Radius |
The radius of the area to be affected by noise reduction for the SSGI (Screen Space Global Illumination) effect. Range of values: [1, 3]. The default value is 1. Console access: render_ssgi_denoise_radius |
| Quality |
The noise reduction quality level for the SSGI (Screen-Space Global Illumination) effect defining the number of samples used. Higher values provide better reduction, but for a performance cost (choosing Medium is enough in most cases). One of the following values:
Console access: render_ssgi_denoise_quality |
| Intensity |
The noise reduction intensity for the SSGI (Screen Space Global Illumination) effect. Higher values provide a less noisy, but more blurred result. Range of values: [0.0f, 1.0f]. The default value is 0.2f. Console access: render_ssgi_denoise_intensity |
| Gaussian Sigma |
The sigma parameter of Gaussian blur used for noise reduction for the SSGI (Screen Space Global Illumination) effect. This parameter controls the amount of blur applied. Range of values: [0.0f, 100.0f]. The default value is 10.0f. Console access: render_ssgi_denoise_gaussian_sigma |
| Threshold |
The threshold value for color difference of neighboring pixels used for noise reduction for the ssgi (screen space global illumination) effect. Blur is applied when the color difference is less than the threshold value. Notice Setting too high values result in blurring the whole image. Range of values: [0.0f, 1.0f]. The default value is 0.1f. Console access: render_ssgi_denoise_threshold |
