Unreal 4.25.X changes and issues

New UE version 4.25 - some changes / issues. Lets put them in one topic for an easy overview and catching up..

4.25.0 preview 1
- Too bad, the new Epic-GPU lightmass plugin is not in this version. Target might be 4.26 (if you build the dev branch you get 4.26)
- When you make a build for Quest, it will fail and you need to install a newer NDK (21). Normally its in the UE extras directory. Not yet. Find it here https://developer.android.com/ndk/downloads ; Download it, extract the zip and put it in the NVPACK dir. Change the Dir in the project settings.
- With the new NDK, building for Quest works but it immediately crashes on Quest. There are a few new project settings but haven't found the right combo yet. ADB logcat has: 'Abort message: 'The requested API version in ovrInitParms (1.1.29.0) is not compatible with this version of VrApi Loader (1.1.31.0)!''. No clue if this is a user setting or a Engine-bug. Reported at Epic.
- update 03-05: tried both building a new project and re-using an existing and working 4.24 project. Both crash on Quest. Only difference is the existing project takes longer to crash.
- update 03-06 "The crash on Quest is known and we're working to have it fixed prior to full 4.25 release."

    My app built on UE 4.25 failed to launch on Oculus quest...
    I could somehow find the error log, but I don't know how to fix the error.
    Does Anyone know if this is an engine bug or my configuration issue?
    Thanks,

    @ikyhdst No clue. There are a few issues on Google regarding ... libUE4.so so maybe do a search for that.
    A few suggestions;
    - are you using Vulkan? If so, try if vulkan is disabled.
    - in the project settings - plugins - oculusVR; disable the auto-enabled splash screen. This one caused a few crashes for me

    @MaxArch
    Thank you for your suggestion!
    But I found out this issue was caused by my configuration.
    I managed to solve the problem by changing NDK API Level to `android-19` from 'latest' in "Project Setting|Platforms|Android SDK" .
    However I appreciate your advice!

    I'm getting an error with 4.25 oculus src, when I try cook my project. It works with a brand new project, but as soon as I start adding my content I get the following error: use of undefined type 'APlayerController'. Compiles fine in visual studio, only when I cook I get this error. Any suggestions?

    Got mine to build but it crashes almost instantly after start and gives this error.
    Seems to be something with Vulkan. Need to test without Vulkan next.

    Was able to build my project and had no crashes using OpenGL.
    Got some widget issues tho, but not sure if they stem from the engine upgrade.

    Just updated to the official 4.25.0. Only did one test build. First impression;
    - arm 64 works again for Quest builds.
    - splash screen (default settings in project settings-Oculus) is still broken
    - shader compiling seems a bit faster (havent timed before/after upgrading though)

    will update when I have had more time to test

    @@Mad_Methods No - Oculus hasn't released/created it for UnrealEngine yet. No eta as far as I know.


    Re the splash screen seems better to use the XR splash screen APIs Add Loading Screen Splash from the new XR Loading Screen function library. Not much docs about this

    Color Grading Issue on Oculus GO ( Been an issue since 24.0 ). Tried also OculusSource 4.25.0 , and only the Client Color = UNMANAGED come to be something near 4.23 version. Also FPS take a massive hit on this setting...

    Ticket is here : https://developer.oculus.com/bugs/bug/2633758633400646/

    Not to mention that Oculus GO inputs are broken, but atleast work with oculus touch ones

    Seems like the input mapping for the motion controller menu buttons (the flat buttons below the thumbsticks) are not working in 4.25.  In 4.24, they were Gamepad Special Left / Right.  Anyone know how to access them now?

    EDIT: I found it.  It is Oculus Touch (L) Menu for the left controller.  I guess they already had that in there and just dropped support for the 'Gamepad Special'.

    I tried with/without vulkan enabled. I also tried to set "NDK API Level to `android-19`" as suggested by  ikyhdst somewhere above.

    @ikyhdst , could you be so kind to show me the rest of your project settings as well? Vulkan? Mobile HDR? I must admit I'm a bit lost here...

    I'll try again with the updated 4.25.1 binary from Epic, maybe that gives a better result.
