Cannot open HandsTrainSample because Engine modules are out of date.
I wanted to try out Hand Tracking with UE4, and I just did git clone the engine source from Oculus github, and build the engine following the instruction in the Oculus website. I cloned 1e09d2f (the latest one) from branch 4.25, which is release "oculus-4.25.3-release-1.51.0-v19.0" and built the engine using Visual Studio 2019. It worked fine, I could make a new project. I could also open HandSample project and it works great with Oculus Quest & Link. But I couldn't open HandsTrainSample. I built the engine and clicked Debug/Start a new instance in Visual Studio, then it opened up the editor. Then I chose the sample, but I couldn't open it. I also tried to open .uproject directly but it just says "The following modules are missing or build with a different engine version: HandsTrainSample Would you like to rebuild them now?" and if i go Yes, then I get Missing Modules error with the message "Engine modules are out of date, and cannot be compiled while the engine is running. Please build through your IDE." and I couldn't open it. I guess I have to find and fix errors in VS but I don't even know where I can get .sln file for this project so which I need to see errors in VS. I tried Generate Visual Studio project files from HandsTrainSample.uproject but .sln file wasn't generated in the same directory although I got no error. This is my first time to build the engine from source and I might misunderstand some stuff. I hope someone helps me with it.4.7KViews1like5Comments
How can I display oculus friend list in Game for UE4?
I would like to display friends and the ability to send invite using the Quest 2's native UI like I have seen in other games developed in Unity. A quick look on the UE4 engine's plugin OnlineSubsystemOculus, it doesn't have IOnlineExternalUI implemented. So, I am curious if this is not yet supported for UE4.1.8KViews0likes3Comments
Oculus Quest and WebBrowser (WidgetInteraction) Widget
Hi everyone, I am having a problem getting any interaction with the WebBrowser Widget with the WidgetInteractions Component on Quest. On Linux, Windows etc (they use usually CEF as their Web access platform) it works but on the Quest it doesn't react at all. UMG Widget, like Buttons, Checkboxes works. Only the WebBrowser seems not to work. Is that a known issue? Are there any permissions needed for the Quest?1.1KViews0likes1Comment

New Meta XR Plugin -> Oculus VR plugin depricated when?
Hi! We are still heavily in producing a multiplayer-windows-based VR app using the OculusVR plugin (together with UE4.27.2 and life is good) . Since there has been a complete new MetaXR plugin released we are wondering about how long the old Oculus Plg will work since I assume that on some point there will be updates on the headsets that will produce errors by the communication between Oculus app (which I assume will be replaced by some "Meta app" in the near future too) and the Unreal plg? So if anyone knows something about how long the OculusVR-plg will be supported I'd appreciate an answer. Thank you very much!1.3KViews1like0Comments
Hang on headset launch - Problems getting started, is Mac *really* supported?
I'm trying to get started developing for the Quest 2 on my Mac. I'm new to Android, UE4 and the Oculus Quest 2. I've followed the instructions to build the Oculus fork of UE4 from source, installed Android Studio and set things up. I did have to modify the UE4 source to get it to compile. See PR #108 to github.com/Oculus-VR/UnrealEngine/pull/108 (I'm not allowed to post proper links yet). I also had an issue with a type -P command in SetupAndroid.command failing because the default Mac shell zsh doesn't appear to support the -P option to type. The two things make me wonder if developing on a Mac is actively being supported? I have been able to build the sample template project in UE4. However, on launch, everything hangs, and the last message in the output log is: LogPlayLevel: Running: /Users/erland/Library/Android/sdk/platform-tools/adb -s <serial> shell am start -n com.YourCompany.QuestOS/com.epicgames.ue4.GameActivity LogPlayLevel: Starting: Intent { cmp=com.YourCompany.QuestOS/com.epicgames.ue4.GameActivity } In the headset I first see the three dots, and then just a "black" world. At some point during troubleshooting, I got some messages indicating the .obb file was not found, and download of it was starting which might have I'm running Android Studio 3.6.3, UE 4.25 from source, MacOS 10.15.7, XCode 12.4, Oculus VR Plugin version 1.55.0.

But there is no "/OculusVR/Materials" that can be selected, and I'm wondering if this is due to the plugin not working completely?5.2KViews1like5Commentsshared spaces in you own UE4 project?
Hi, I have the sharedspaces API working in our own project based on the example project but basic replication of some actors isnt working as i would have expected. We have the VRE plugin working and our pawn is replicating as exepected. We have a simple ball in the game as a test actor and it is not replicating , as the client moves it it is not seen on the server and then is reset when the server toouches it. Has anyone else got sharespaces API working on UE4 with actor replication? Would like to confirm we are not bleeding edge here...2KViews0likes2Comments

Quest 2 Battery Level on Windows Platform
Hi everybody, is there a way for a Windows Build to retrieve the battery level of the Quest 2? I think "Get Battery Level" from the "Optional Mobile Blueprint Library" will only work if you develop a native android app. Using the nodes provided by the OVR Plugin there seems to be no way at all?
