Struct GlobalIlluminationSettings

Contains settings for Global Illumination effect rendering.

Assembly: FlaxEngine.dll
File: Engine/Graphics/PostProcessSettings.h
Syntax
public struct GlobalIlluminationSettings : public ISerializable

Fields

BounceIntensity

Global Illumination infinite indirect lighting bounce intensity scale. Can be used to boost or reduce GI effect for the light bouncing on the surfaces.

Declaration
public float BounceIntensity = 1.0f
Field Value
float

Distance

Camera-centered draw distance of the Global Illumination effect. Scene outside the range will use fallback irradiance. DDGI automatically derives its cascade layout from this distance and the global probe spacing, so continuously blending this value can recreate probe resources and cause a visible lighting reset.

Declaration
public float Distance = 20000.0f
Field Value
float

FallbackIrradiance

The irradiance lighting outside the GI range used as a fallback to prevent pure-black scene outside the Global Illumination range.

Declaration
public Color FallbackIrradiance = Color::Transparent
Field Value
Color

IndirectResolution

The indirect lighting render resolution. Full gives better quality, but half improves performance.

Declaration
public ResolutionMode IndirectResolution = ResolutionMode::Full
Field Value
ResolutionMode

IndirectShadowsStrength

Indirect lighting shadows intensity. Default is 1 for fully opaque shadowing, lower values bleed the lighting into shadowed areas. Can be sued for artistic control over GI.

Declaration
public float IndirectShadowsStrength = 1.0f
Field Value
float

Intensity

Global Illumination indirect lighting intensity scale. Can be used to boost or reduce GI effect.

Declaration
public float Intensity = 1.0f
Field Value
float

Mode

The Global Illumination mode to use.

Declaration
public GlobalIlluminationMode Mode = GlobalIlluminationMode::None
Field Value
GlobalIlluminationMode

OverrideFlags

The flags for overriden properties.

Declaration
public GlobalIlluminationSettingsOverride OverrideFlags = Override::None
Field Value
GlobalIlluminationSettingsOverride

Reflections

The indirect specular reflections rendering mode to use.

Declaration
public ReflectionsMode Reflections = ReflectionsMode::EnvironmentProbes
Field Value
ReflectionsMode

ReflectionsResolution

The indirect specular reflections render resolution. Full gives better quality, but half improves performance.

Declaration
public ResolutionMode ReflectionsResolution = ResolutionMode::Full
Field Value
ResolutionMode

TemporalResponse

Defines how quickly GI blends between the current frame and the history buffer. Lower values update GI faster, but with more jittering and noise. If the camera in your game doesn't move much, we recommend values closer to 1.

Declaration
public float TemporalResponse = 0.9f
Field Value
float

Methods

BlendWith(GlobalIlluminationSettings& other, float weight)

Blends the settings using given weight.

Declaration
public void BlendWith(GlobalIlluminationSettings& other, float weight)
Parameters
GlobalIlluminationSettings other

The other settings.
float weight

The blend weight.
