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."

    Damn... I would say it's just a Preview 1, but then again why would it not work if 4.24 worked... Damn Epic!!

    Btw, they moved all XR bug reports relevant to Quest from 4.25 to 4.26 which who knows will be coming out (by Christmas 2020 ? ).

    4.25p2 is out.. Doesn't look like there are any Quest specific (or Oculus VR specific) fixes :/
  • MaxArchMaxArch Posts: 195 Oculus Start Member
    Tested 4.25.0.p2 Can't even make an android build now because its missing essential stuff. Copying some from the 4.24 folders only results in new missing stuff. Reported.

    The next message is probably the java message. copy that folder over too. Now everything builds successfully at least.

    @rasamaya well, if it builds and runs for you on Quest, could you please check if Niagara works in VR and performs as well as Cascade ?  o:)
  • MaxArchMaxArch Posts: 195 Oculus Start Member
    @rasamaya did you run the app on the Quest as well? I copied those folders and it builds now but the app still crashes immediately on the Quest for me.

    Builds, but crashes right away. Was just making progress, one step at a time. Upon playing in headset, it crashes and its a known error they are working on. Been trying to get it to work too lol.

    Updated to 4.25.0.p3 Still Android errors so still no builds for Quest possible.
    On p2 I got a reply from Epic, they couldn't reproduce the error. Added a bit more info but no response.

    Updated to 4.25.0.p4. Finally builds for Android work again but... when opening the app on the Quest its endless stuck at the three blinking dots. Have to reboot the Quest to get control back. Used a working 4.24 project to test. Anyone succeeded in deploying for Quest in 4.25.0.p4?
    Update April 2: yesterday tested p5, still the same. Reported already.

    Did you go through the new Android studio process for your builds?
    main reason I haven't tested it yet :D

  • MaxArchMaxArch Posts: 195 Oculus Start Member
    @aussieburgerVR Yes, I did. All is installed and build is successful. We've seen something like this before so waiting for p6.
  • aussieburgerVRaussieburgerVR Posts: 252 Oculus Start Member
    Finally got around to trying it on the Go and has a black screen on load - no surprise I guess considering similar behavior on the Quest as you guys mentioned
  • MaxArchMaxArch Posts: 195 Oculus Start Member
    just tried P6 - still the same problem - three blinking dots and have to hard-reboot the Quest to get control back. Too bad. Hoping for P7...

    I think it's the integration version mismatch. Whatever comes with stock UE4 is few version behind from whatever is current on HMD and integration version should match (+/-1 version) HMD OS version, afaik.

    I would expect Epic has at least one Quest to test and a direct communication with devs at Oculus. I guess Epic has bigger problems to solve first.

    What's new in 4.25.0p6?

    No, Epic just doesn't care for VR as much as they do for Fortnite and AAA third party games in the pipeline.

    Epic released preliminary notes on what's new in 4.25 and you can read it on the UE4 forum. As for VR, gotta wait for Oculus to release their 4.25 fork to know what's new in it for Oculus VR.
