XR Compositing

SettingDescription
XR Compositing Enables a pass for use with CloudXR streaming and SDI-video compositing (experimental)
Composite in Linear Space Applies the XR Compositing pass prior to any other post processing. Therefore doing any compositing work in Linear space, prior to exposure or tone mapping adjustments.
Composite in Editor Enables alpha compositing with a backplate texture or SDI video input, as opposed toto outputting the rendered image with an alpha channel for compositing outside, either by saving to EXR images or outputting the rendered image to a Cloud XR stream
Default Backplate Texture The path to a texture to use as a backplate
Default Backplate Color A constant color to use instead of a backplate texture, if a backplate texture is not set
Enable Lens Distortion Enables distortion of the rendered image using a set of lens distortion and undistortion maps provided in the next two settings. Each of these settings is expected to point toa <UDIM> EXR texture set, containing one image per each of the discrete focal length values specified in the array of float settings under /rtx/post/lensDistortion/lensFocalLengthArray(to be exposed here in the future)
Lens Distortion Map The path to a <UDIM> EXR texture storing the distortion maps for specified focal lengths
Lens Undistortion Map The path to a <UDIM> EXR texture storing the un-distortion maps for specified focal lengths
