Quest Pro Eye-tracker not detected in Unreal Engine (Air link)
Hello all, I am trying to do eye-tracking research with Unreal Engine 5.3.1 + Quest Pro with OpenXR plugin running PCVR but ran into an issue that UE does not seem to detect the eye-tracker (I got constant zero) so I am wondering if anyone has experience with it. I have "eye tracking over Oculus Link" enabled in Oculus App and have enabled eye-tracking in Quest Pro, and the following blueprint is attached to the VRPawn Event Graph, and I am using Air Link while development the app. The output is using LabStreamingLayer (if someone has experience with it also love to get your input) but I think the issue is at the connecting to the eye-tracker side. I tried to use the following nodes to check if the eye-tracker is connected and it gave me false. Thanks so much!! It is really hard to find Quest Pro eye-tracker resources......
UE4 pc build with oculus-link can not use hand tracking
I downloaded the oculus branch of UE4 4.27.2 and run the HandPoseShowcase example. It works well in VR preview with oculus-link on Quest2. But in Lauhch mode or in win64 build , I can not see any hand models. I got the error message "LogOcHandTracking: Error: Failed to get mesh or skeleton data from Oculus runtime." in the log window. I found the problem is in file OculusHandTracking.cpp : ovrpResult SkelResult = FOculusHMDModule::GetPluginWrapper().GetSkeleton2(OvrSkeletonType, OvrSkeleton); ovrpResult MeshResult = FOculusHMDModule::GetPluginWrapper().GetMesh(OvrMeshType, OvrMesh); These two function did not return right value. Is there anything I can do to make hand tracking working on a pc build?
