OS: 12.0 Beta I'm interested in the Object Capture API and am trying to get the sample app to work. https://developer.apple.com/documentation/realitykit/taking_pictures_for_3d_object_capture https://developer.apple.com/documentation/realitykit/creating_a_photogrammetry_command-line_app/ After trying a few times, I noticed that the output doesn't change much even if Depth (.TIF) and Gravity (.TXT) aren't in the folder. I wanted to use Depth, so I tried using PhotoGrametorySample. Because, I noticed PhotoGrametorySample.depthDataMap The session was successfully created by using the same CVPixelBuffer as this. AVCapturePhoto.depthData.converting (toDepthDataType: kCVPixelFormatType_DisparityFloat32) .depthMapData However, the output from the session is .invalidSample only for the id containing the depth. [command-line app log] Successfully created session. (PhotogrammetrySample API) Using request: modelFile(url: ***, detail: RealityFoundation.PhotogrammetrySession.Request.Detail.full, geometry: nil) Invalid Sample! id=1 reason="The sample is not supported." Invalid Sample! id=2 reason="The sample is not supported." Invalid Sample! id=3 reason="The sample is not supported." Invalid Sample! id=4 reason="The sample is not supported." ... What is this reason ? "The sample is not supported." Is there sample code to use Depth in the process?

iPhone12 Pro, iOS 15.0.1  * Occurs on most iPhone devices I am using True-Depth on the Front side that I got from ARKit for my own application. (ARFrame.capturedDepthData) ...     func session(_ session: ARSession, didUpdate frame: ARFrame)     {         // get capturedDepthData         guard let depthData = frame.capturedDepthData else { return } ... There are many other processes, so the CPU gets hot as soon as I launch the app. When the CPU is hot, the True-Depth frame rate drops from about 15 to 5 fps. Is there a way to maintain a constant frame rate? Is there a way to get a lower resolution? QVGA resolution is enough for my app. A simple code is attached below.
