IsCasting from the [Oculus.Settings.MixedReality] section in the Saved/Config/Windows/Engine.ini file.
bIsCasting (GetIsCasting/SetIsCasting): Turns MRC on and off. Does not get saved to or loaded from ini.CompositionMethod (GetCompositionMethod/SetCompositionMethod)
ExternalComposition: Default. The casting window includes the background and foreground view.DirectComposition: Rift only. The game scene is composited with the camera frame directly.BindToTrackedCameraIndex (BindToTrackedCameraIndexIfAvailable/GetBindToTrackedCameraIndex): Index of the calibrated external camera to which the in-game MRC camera should be bound.ClippingReference: Specifies the distance from the camera to the mixed reality capture casting background/foreground boundary. For stationary experiences, set to CR_TrackingReference to use the distance to the tracking reference. For room-scale experiences, set to CR_Head to use the distance to the HMD (the default setting).bUseTrackedCameraResolution: Set to True for the casting viewports to use the same resolution as the camera in the calibration process.WidthPerView: Set bUseTrackedCameraResolution to False to set the width of each casting viewport (foreground, background, or direct-composited).HeightPerView: Set bUseTrackedCameraResolution to False, to set the height of each casting viewport (foreground, background, or direct composited).CapturingCamera (GetCapturingCamera/SetCapturingCamera): Set CompositionMethod to DirectComposition to choose which physical camera device should provide the video frame for compositing. Available options are Web Camera 0 and Web Camera 1.CastingLatency - Set CompositionMethod to ExternalComposition to set the latency of the casting output. This setting may be used to help sync with the camera latency in the external composition application.ExternalCompositionPostProcessEffects: Set CompositionMethod to ExternalComposition to set the amount of post process effects that are shown in the mixed reality capture. Setting it to Off will disable all post-process effects. Setting it to On will enable post-process effects, but may cause visual inaccuracy.BackdropColor: Set CompositionMethod to ExternalComposition to show the color of the backdrop in the foreground view.HandPoseStateLatency: (Deprecated) Set CompositionMethod to DirectComposition to add a delay in seconds (up to a max. 0.5) to the tracked controllers in the composited scene to correct for camera latency.ChromaKeyColor: (Deprecated) This specifies the approximate color of your green screen as a compositing reference. The default value is Color.green, which matches a typical general green screen under good lighting conditions.ChromaKeySimilarity: (Deprecated) This determines the visibility of pixels based on color. When the distance between pixel color and chromaKeyColor is less than chromaKeySimiliarity, the pixel is hidden. Increase this value if the green screen is partially visible and reduce this value if the person in the scene partially disappears.ChromaKeySmoothRange: (Deprecated) This defines a small range of color distance between the pixel and the green screen in which the video frame pixel will be rendered as semi-transparent. Increase this value to make the person’s image smoother and decrease the value to sharpen the image.ChromaKeySplitRange: (Deprecated) This defines a small range of color distance between the pixel and the green screen, in which the video frame pixel will be desaturated. Increase this value to reduce green edges around the person’s image and decrease it if the person’s image looks overly desaturated.VirtualGreenScreenType: This specifies the type of virtual green screen based on the guardian boundary type. Available options are Off, OuterBoundary, or PlayArea.DynamicLightingDepthSmoothFactor: This determines the smooth factor of the lighting. Larger values make dynamic lighting effects smoother, while values that are too large make the lighting look flat.
