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."

    They changed the way 2-players on one machine works in 4.25.  Now if I play with 2 clients (they got rid of Dedicated Server?), both viewports show the view from my VR headset.  It used to show the 2nd client with his own non-VR view... anyone know how to fix that?

    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



    @GRADGR can you elaborate on the CLIENT COLOR setting, please? I can't find any info about it.

    In 4.25 if you set number of players to 2, both windows show the same VR view now.  In 4.24 and before, the second player had his own view.  Is there any way to fix this?

    I guess he's referring to either of these two docs:


    not tried myself yet though as building a "development" build with "for distribution" ticked is a good workaround for now.

    I have, with 4.25.1 + 1.50 integration. Seems to be working a way better than in 4.24 and I dare to say as good as ES3.1 (although still uses more RAM)

    @motorsep And no glitches? Last time I tested there always were some purple dots in the view without any logic to them.

    Haven't seen those yet (saw them in the older versions). Are you seeing them with OC fork of 4.25.1 + 1.50 ? If so, have you submitted a new bug report?

    @motorsep Was just checking. Haven't tested or built anything myself the last month. Too busy with my arch work.
