Post-Processing

Post-Processing allows you to toggle on and off, as well as tune the look of each of the supported post-processing effects in Remix.

Ref	Option	RTX Option	Default Value	Description
1	Composite
2	Enable Fog Checkbox	rtx.enableFog	Checked
3	Fog Color Scale	rtx.fogColorScale	0.250
4	Max Fog Distance	rtx.maxFogDistance	65504
5	Bloom
6	Bloom Enabled Checkbox	rtx.bloom.enable	Checked
7	Bloom Sigma	rtx.bloom.sigma	0.100
8	Bloom Intensity	rtx.bloom.intensity	0.06
9	Auto Exposure
10	Eye Adaptation Checkbox	rtx.autoExposure.enabled	Checked	Automatically adjusts exposure so that the image won’t be too bright or too dark.
11	Average Mode Dropdown	rtx.autoExposure.exposureAverageMode	Median	Average mode. The mean mode averages exposures across pixels. The median mode is more stable for extreme pixel values. Choices: Mean & Median
12	Adaptation Speed	rtx.autoExposure.autoExposureSpeed	5.000	Average exposure changing speed when the image changes.
13	Min (EV100)	rtx.autoExposure.evMinValue	-2.000	Min/Max values are tuned by moving from bright/dark locations in game, and adjusting until they look correct.
14	Max (EV100)	rtx.autoExposure.evMaxValue	5	Min/Max values are tuned by moving from bright/dark locations in game, and adjusting until they look correct.
15	Center Weighted Metering Checkbox	rtx.autoExposure.exposureCenterMeteringEnabled	Unchecked	Gives higher weight to pixels around the screen center.
16	Center Metering Size	rtx.autoExposure.centerMeteringSize	0.500	The importance of pixels around the screen center.
17	Exposure Compensation Checkbox	rtx.autoExposure.useExposureCompensation	Unchecked	Uses a curve to determine the importance of different exposure levels when calculating average exposure.
18	Exposure Compensation Graph Values	rtx.autoExposure.useExposureCompensation	1 (for all Curve Values)	Curve Values for Exposure Compensation
19	Reset			Reset Curve values for Exposure Compensation to default
20	Tonemapping
21	Tonemapping Mode Dropdown	rtx.tonemappingMode	Local	Global tonemapping tonemaps the image with respect to global parameters, usually based on statistics about the rendered image as a whole. Local tonemapping on the other hand uses more spatially-local parameters determined by regions of the rendered image rather than the whole image. Local tonemapping can result in better preservation of highlights and shadows in scenes with high amounts of dynamic range whereas global tonemapping may have to compromise between over or underexposure. Choices: Global & Local
22	Mip	rtx.localtonemap.mip	3	Top mip level of tone map pyramid.
23	Display Mip	rtx.localtonemap.displayMip	0	Bottom mip level of tone map pyramid.
24	Boot Local Contrast Checkbox	rtx.localtonemap.boostLocalContrast	Unchecked	Boosts contrast on local features.
25	Use Gaussian Kernel Checkbox	rtx.localtonemap.useGaussian	Checked	Uses a gaussian kernel to generate a tone map pyramid.
26	Finalize with ACES Checkbox	rtx.tonemap.finalizeWithACES	Checked	Applies ACES tone mapping on final result….
27	Exposure Level	rtx.localtonemap.exposure	0.750	Exposure factor applied on average exposure.
28	Shadow Level	rtx.localtonemap.shadows	2.000	Shadow area strength. Higher values cause brighter shadows.
29	Highlight Level	rtx.localtonemap.highlights	4.000	Highlight area strength. Higher values cause darker highlights.
30	Exposure Preference Sigma	rtx.localtonemap.exposurePreferenceSigma	4	Transition sharpness between different areas of exposure. Smaller values result in sharper transitions.
31	Exposure Preference Offset	rtx.localtonemap.exposurePreferenceOffset	0	Offset to reference luminance when calculating the weights a pixel belongs to shadow/normal/highlight areas.
32	Post FX
33	Post Effect Enabled Checkbox	rtx.postfx.enable	Checked	Enables post-processing effects
34	Motion Blur Enabled	rtx.postfx.enableMotionBlur	Checked	Enables motion blur post-processing effect.
35	Motion Blur Noise Sample Enabled	rtx.postfx.enableMotionBlurNoiseSample	Checked	Enable random distance sampling for every step along the motion vector. The random pattern is generated with interleaved gradient noise.
36	Motion Blur Emissive Surface Enabled	rtx.postfx.enableMotionBlurEmissive	Checked	Enable Motion Blur for Emissive surfaces. Disable this when the motion blur on emissive surfaces cause severe artifacts.
37	Motion Blur Sample Count	rtx.postfx.motionBlurSampleCount	4	The number of samples along the motion vector. More samples could help to reduce motion blur noise.
38	Exposure Fraction	rtx.postfx.exposureFraction	0.4	Simulate the camera exposure, the longer exposure will cause stronger motion blur.
39	Blur Diameter Fraction	rtx.postfx.blurDiameterFraction	0.02	The diameter of the circle that motion blur samplings occur. Motion vectors beyond this circle will be clamped.
40	Motion Blur Minimum Velocity Threshold (unit:pixel)	rtx.postfx.motionBlurMinimumVelocityThresholdInPixel	1	The minimum motion vector distance that enables the motion blur. The unit is pixel size.
41	Motion Blur Dynamic Deduction	rtx.postfx.motionBlurDynamicDeduction	1	The deduction of motion blur for dynamic objects.
42	Motion Blur Jitter Strength	rtx.postfx.motionBlurJitterStrength	0.6	The jitter strength of every sample along the motion vector.
43	Fringe Intensity	rtx.postfx.chromaticAberrationAmount	0.02	The strength of chromatic aberration.
44	Fringe Center Attenuation Amount	rtx.postfx.chromaticCenterAttenuationAmount	0.975	Control the amount of chromatic aberration effect that attenuated when close to the center of screen.
45	Vignette Intensity	rtx.postfx.vignetteIntensity	0.8	The darkness of the vignette effect.
46	Vignette Radius	rtx.postfx.vignetteRadius	0.8	The radius of the vignette effect starts. The unit is normalized screen space, 0 represents the center, 1 means the edge of the short edge of the rendering window. So, this setting can be larger than 1 until it reaches the long edge of the rendering window.
47	Vignette Softness	rtx.postfx.vignetteSoftness	0.2	The gradient that the color drops to black from the vignetteRadius to the edge of the rendering window.
