Unreal Engine 4.25 Preview

maxbrown · March 10, 2020, 2:53pm

updated to 4.25.0.p2
When trying to build for Quest you get a ‘license not accepted’.
When going to project settings trying to accept the license (android) it reports;
‘unable to read …/…/…/Engine/Source/ThirdPaty/Android/package.xml’

edit1: copied the package.xml from 4.24 to 4.25, now error ‘could not find part of the path ‘c:\program files\epic games\ue_4.25\engine\build\android\java\javaTemplates’’

Still no Chaos. Looked for 4.25P2 source(github) not there.

rasamaya · March 10, 2020, 4:26pm

That was a lot of fixs fast, go to test some things again

ChesherZ · March 10, 2020, 4:31pm

Heya! I’ve been testing the new Single Layer Water Blend Mode for the Materials and its awesome!
BUT!
I have noticed that it doesn’t seem to support Planar Reflections or reflections from Reflection Capture Actors, SSR work fine, but that’s about it.
Anywho it seems like a strange limitation or bug? Has anyone else encountered this?
I first noticed in Preview 1, but is still there in Preview 2

rasamaya · March 10, 2020, 5:19pm

yup copy that folder over too, I dont overwrite anything, just copy whats not there from 4.24. I can now build for android in 4.25 again.

Parth_Patel · March 10, 2020, 6:24pm

We are seeing the same on windows machine. Is this a bug?

Novezeil · March 10, 2020, 8:51pm

Same crashed start again, 4.25p2 on OSX 10.14.6

frostic · March 10, 2020, 9:26pm

When trying to build my c++ project i get the following error and can’t figure out why… my game has a dlc and i’m using launch profile
to package but im getting an error, it used to work in 4.24, i’m using the same settings in the build profile but its erroring.
what do you think could be causing this issue?

ERROR: Missing precompiled manifest for ‘Launch’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in Launch.build.cs to override.

in development setting for build i get this:

I get crash when try to turn on new Anisotrophic function in Project Setting/Rendering/Anisotrophic BDRF. Engine asks to restart and I get this:

frostic · March 10, 2020, 9:42pm

It even has this error without the dlc. i don’t get what the error means at all do you?

ERROR: Missing precompiled manifest for ‘Launch’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in Launch.build.cs to override.

WARNING Don’t enable the audio modulation plugin, it is missing tons of files and will kill your project.
my project will no longer open after enabling this plugin. needed to go in my ini and remove it from there to open my project again.

JW3153 · March 11, 2020, 4:10am

I get the same crash in 4.25 Preview 2 when enabling Anisotrophic under Rendering.

how to fix it?

anonymous_user_c14940f8 · March 11, 2020, 7:30am

This worked for me:

Open 4.24 and check your engine scalability settings
Set to Epic / Cinematic (medium does not work)
Save everything and open 4.25

See here:

DevJMD · March 11, 2020, 11:00am

Just a quick one: My AV is flagging libUnrealInsights-Slate.debug as a virus. Almost certain it’s a false/positive, but I thought I’d let you know as I know in the past that certain code changes can be picked up incorrectly.

EddieChristian · March 11, 2020, 11:59am

Does Unreal World Composition Still Instantly crash the editor as soon as you turn on Raytracing in the Project Settings and hit Play?

ZacD · March 11, 2020, 2:18pm

Thank you guys for fixing this so quickly! Fixed within 3 days of me submitting the report.

EoinOBroin · March 11, 2020, 11:17pm

@ Also getting that same error when packaging in 4.25 (Worked fine in 4.24). No extra plugins enabled outside of default other than Niagara.

UATHelper: Packaging (Windows (64-bit)): ERROR: Missing precompiled manifest for ‘Launch’. This module was most likely not flagged for being included in a precompiled build - set ‘PrecompileForTargets = PrecompileTargetsType.Any;’ in Launch.build.cs to override.

**EDIT: I can reproduce this on a blank third person template when packaging (the only requirement for the error to occur is at least one C++ class is in the project, then it fails to build when packaging. It builds fine if there are no C++ classes in the project) **I have filed a bug report

NilsonLima · March 11, 2020, 11:33pm

I didn’t finish all possible tests with several asset I got, but there is one bug really troublesome which is when you set Separate Translucency resolution lower than 100% makes all translucent materials (alpha composite included) to be wrongly rendered in front of all opaque materials and odd square shapes appears at the screen. Putting the value back to 100% makes the rendering to be at the correct placement. I will fill the bug report when I have finished all the tests (had to redo when preview 2 arrived).

Novezeil · March 12, 2020, 12:44am

Thanks, although this specific method didn’t work for me as I have 4 previous versions installed, setting all 4 of them to Cin still doesn’t work (I wonder why though).

What I did is nuke the ~/Library/Application Support/Epic/UnrealEngine/ to force 4.25 create a completely new setting in the .bin file.

Anyway I can see the issue is fixed but not releasing to Github yet, guess in next preview we’ll see it fixed in field.
