bEnableHDRTonemapper Source code

PreviousLUTBlender Source code

LUTBlender parameters used last frame.

SceneHDRTonemapperScale Source code

Bloom,Shape

BloomSizeScaleLarge Source code

Scales the large kernel size. A good number is in the range from 2 to 4. This property is only used if BloomWeightLarge specifies some weight.

BloomSizeScaleMedium Source code

Scales the medium kernel size. A good number is in the range from 0.5 to 1.5.

BloomSizeScaleSmall Source code

Scales the small kernel size. A good number is in the range from 0.1 to 0.5. This property is only used if BloomWeightSmall specifies some weight.

BloomWeightLarge Source code

To adjust the bloom to get an extra outer, more wide spread glow. 0=off If this feature is used, it might costs additional performance depending on the bloom radius. However in some cases it might get faster as the bigger radius is done in lower resolution. The actual weight is computed as the ratio between all bloom weights.

BloomWeightMedium Source code

To adjust the bloom shape to reduce the extra inner and outer weight. Should be bigger than 0. However in some cases it might get faster as the bigger radius is done in lower resolution. The actual weight is computed as the ratio between all bloom weights.

BloomWeightSmall Source code

To adjust the bloom to get an extra inner, more sharp glow. 0=off If this feature is used, it might costs additional performance depending on the bloom radius. However in some cases it might get faster as the bigger radius is done in lower resolution. The actual weight is computed as the ratio between all bloom weights.

MotionBlur

MotionBlurSoftEdgeKernelSize Source code

The radius of the soft edge for motion blur. A value bigger than 0 enables the soft edge motion blur. The method improves motion blur by blurring the silhuette of moving objects. The method works in screen space. Therefore the performance of the method only depends on screen size, not on the object/vertex/triangle count.

PostProcessEffect

bScaleEffectsWithViewSize Source code

affects BlurKernelSize, the attribute is scaled depending on the view size

Scene

bEnableImageGrain Source code

Whether the image grain (noise) is enabled, to fight 8 bit quantization artifacts and to simulate film grain (scaled by SceneImageGrainScale)

SceneColorize Source code

SceneDesaturation Source code

SceneHighLights Source code

SceneImageGrainScale Source code

Image grain scale, only affects the darks, >=0, 0:none, 1(strong) should be less than 1

SceneMidTones Source code

SceneShadows Source code

Tonemapper

TonemapperRange Source code

This tonemapper property allows to specify the HDR brightness value that is mapping to the maximum LDR value. Brighter values will be mapped to white (good values are in the range 2 to 16). Only affects the "Customizable" tonemapper.

TonemapperScale Source code

Scale the input for the tonemapper. Only used if a tonemapper is specified. >=0, 0:black, 1(default), >1 brighter

TonemapperToeFactor Source code

This tonemapper property allows to adjust the mapping of the darker colors (tonemapper toe). As the adjustment is independent per color channel it can introduce slight shifts color and saturation changes. Only affects the "Customizable" tonemapper. 0=linear .. 1=crushed darks (more filmic)

TonemapperType Source code

Allows to specify the tone mapper function which maps HDR colors into the LDR color range.
