getting this as well - no idea how everyone else is able to test these previews 
A reminder to fill out the bug submission form if youâd like to make us aware of the issues you come across. A message here on the thread as well is great to make us aware, but donât forget to fill out the form. Thanks all!
So what does it mean if the response to a bug report is
Hello,
Thank you for submitting your bug report. Please be aware that preview releases are not completely quality tested, and are actively under heavy development, they should be considered as unstable until the final release.
with no issue number?
(the bug in question being that unreal insights does not work at all in 4.25, in neither of the previews so far, which seems like quite a big problem)
looks like there are actual path tracer updatesâŚ
UPDATE!
We have just released Preview 3 for 4.25! Thank you for your continued help in testing the 4.25 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.
For a list of known issues affecting this latest preview, please follow the links provided on the original post in this thread.

Thank you
Iâm excited to say that Preview 3 seems to have fixed this error!! Thank you Epic games!
Assertion failed: !Material->IsDefaultMaterial() [File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/Engine/Private/Materials/Material.cpp] [Line: 335]
@ Looks like the " UATHelper: Packaging (Windows (64-bit)): ERROR: Missing precompiled manifest for âLaunchâ. This module was most likely not flagged for being included in a precompiled build - set âPrecompileForTargets = PrecompileTargetsType.Any;â in Launch.build.cs to override." bug has been fixed in Preview 3, I got a successful packaged build!
Oh man. This is great. The curve editor was so hard to work with before while the sequencer curve editor was pretty good.
Did a speed test in 2 hours with Groom Niagara Physics in 4.25/3.
Groom is getting better & better , only mirror doesnât work.
Is this test using realtime raytracing?
- The UMG Webbrowser canât update web page some times, when modified web pageâs content.
- And when displayâs resolution over 4k, it not refresh well(I have a page there is a div display time, this div well flash every second).
- When will the media player support to play RTSP Streaming?
Realtime raytracing , I got about 40-50 fps on a RTX 2080ti.
thanks for the heads up!
NOT Fixed! UE-86191 âScene Capture Component 2Dâ Causes Big Performance Dip In VR
Fix is on its way! worked with the devs to get this bug squashed! canât wait for the release!
Work around if anyone needs it.
before compile go into your
WindowsEngine.ini and add these lines.
these settings work in 4.20 to 4.25 confirmed.
you will only get 25fps using this âWork Aroundâ in 4.25 there is a serious regression in this component. in 4.24 you get 45fps so it is even worse in 4.25âŚ
but at least the major lag of 3FPS will be gone.

Hello. When Iâm trying to build for Android Iâm getting this error.
âUATHelper: Packaging (Android (ETC2)): ERROR: Unhandled exception: System.IO.IOException: The process cannot access the file âIntermediate\Android\gradle\app\src\main\AndroidManifest.xmlâ because it is being used by another process.â
Iâve reinstalled UE 4.25 but still the error persist.
try going into processes in task manager and close ALL programs that have to do with ue4. even the stub one and reporting tool etc.
then open it and compile. also go into your project folder, rightclick the project folder, goto options, uncheck read only, then apply to all files and subfolders, restart your pc then try again
@StyleMarshal Which is the number of âMax. Bouncesâ set into your postprocess volume (inside section Ray Tracing Reflections) ? The default is 1 and maybe it needs a higher value for you to be able to see the hair reflections. Make sure the checkbox for âInclude Translucent Objectsâ is checked.
Updated to 4.25.0p3, Also Packaging Failed Error when trying to build for Oculus Quest.
Same for brand new 4.25.0.X project and 4.24 converted project to 4.25
UATHelper: Packaging (Android (ASTC)): ERROR: cmd.exe failed with args /c "D:\....\Intermediate\Android\armv7\gradle\rungradle.bat" :app:assembleDebug
Updated Android already by going to c:\NVPack\Chooser and let it update everything
@ : Thx for the Info , I tried all raytracing settings , also Pathtracer. I rendered with Octane for UE4 but no luck. I guess itâs to early , still experimental.
