Hi there, I am working on an application that uses the SRWorks pass-through mode with a Vive Pro in UE4. Until yesterday everything worked fine, however the cameras suddenly stopped sending out images. I can't even run the Experience_Unreal sample or create a blank project - all I see are the default textures. I've attached a screenshot of the VR preview, which mirrors the right eye. On the left eye, I am seeing the default brick wall texture. Also, when I turn my head, I can see, that those textures are simply put on a plane, which is not following my head (as expected). I already tried a number of possible solutions, none of which worked. The things I have tried include: Repairing SRworks Uninstalling and reinstalling SRWorks Reinstalling SteamVR Unplugging the HMD and plugging it into another USB port Rebooting Creating a blank UE project in UE 4.18 Creating a blank UE project in UE 4.25 Reinstalling Unreal Engine Creating a fresh copy of the Experience_Unreal sample in UE 4.18 Unplugging the base stations and re-running the samples (to disable head tracking) ... I am now running out of ideas. Using SteamVR to test the cameras never worked for me and allways shows a "Communication Error". This, however, also has been the case when it worked before. I also can't tell what should have changed to cause this problem in the first place. I have also attached my SR_logs directory. Hope you can help, searching for a solution. Thanks in advance, Carsten. SR_logs.zip @Daniel_Y, @Marios Bikos

Hello, Trying to integrate a "passthrough" feature that will emulate the passthrough feature accessed by the double tap on power button on the Vive Focus Plus, so I can use the image to setup the virtual environment for my users. However, we're running into a problem : when the application is launched, if the headset enters power saving mode and the application is paused, the camera doesn't work and update anymore. Unity version is 2018.3.0f2, WaveSDK version is 3.1.94. If anyone has a bit more stability with their camera usage in their application, I would love to know how you made it.
