Unreal Engine 4.25 released!

[Maximum-Dev]

Is that with or without raytracing?

Without RT.

Hey everyone, I am curious abut the section for Advanced Users. How do you actually extend the Painter to paint extra vertex attributes? It would be awesome to paint custom attributes in engine and access them in Materials.

I want to build for Android and followed this steps Updates to required setup for Android NDK 21 in Unreal Engine 4.25 - Unreal Engine but when I run SetupAndroid.bat I have a warning
‘Failed to find package llbd;3.1’

Does the Azure Spatial Anchors implementation work with any WMR headset or is it solely supported for Hololens?

Looks like 4.25 has broken the ability to package Text3D components - Can someone double check? I had it turned on and got a ■■■■ storm of fail on packaging, then turned it off and I got warnings that it was missing but all the errors went away.

Virtual texture lightmaps seem to have been broken by 4.25, I haven’t found a permutation of settings that fixes it yet. Anyone else had this issue? I saw someone mention it for preview 5 here and never saw any followup:

Spline Meshes don’t have collision in Packaged game when it’s spawned or altered at runtime.
I already reported this for 4.24 - it was working properly in 4.23, so it was 4.24 that introduced this bug. The issue is still here, in 4.25. More info:

Please fix this.

I filed a bug report, but it looks like SSR is totally busted if you change the Anti Aliasing Method to anything but TemporalAA.

Same here. Very easy to reproduce, any reflective material will show this issue:

Steam doesn’t load in 4.25 how was this missed.

Love the new Mode tabs in 5.25. Few comments though to make a good thing better:

1. Lots of space on my 4K monitor so in order to use the wasted space to the right of main menu bar, I enabled the tabs (press on the little yellow triangle) and dragged-and-dropped the main bar and the mode side by side. Much efficient use of space.
2. Even better; I could put the the two tabs together side by side… I hope this becomes the default UI, specially the tabbed mode; works even with smaller monitors.
3. I don’t know if it’s just me but the mode tabs last icon keeps flickering between the icon and the >> arrows (usually these show up when there isn’t enough space but there is ample space (Nvidia RTX 2070, Windows 10).
4. I wish the default “Select” mode get its horizontal menu bar like the rest of them instead of this 90’s looking vertical bar; it could use the same icons currently used but live in its own tab… Currently It’s a waste of space when it’s not being used.
5. Edit: in fact if each of the modes sits at the top, each with it’s own tab then the modes button in the main toolbar would be redundant.

Finally, appreciate any comment from UE4 team, thanks!

I can’t upgrade from 4.23
I trigger a break point here

Looks like all my BP classes that read values from Structs are having this issue. What can I do ?

‘Use Emissive for Static Lighting’ seems to be screwed up, injecting ~10X more brightness than before in some cases. Will try and get a repro project.

(edit: fixed here: https://github.com/EpicGames/UnrealEngine/pull/7025 )

Oh, I thought I was using ContainerPtrToValuePtr somehow wrong, because whatever I tried, it kept crashing.

Looks like it’s not just me. Do you think you can submit a bug report?

@zacbored Open SetupAndroid.bat in a text editor, remove **“lldb;3.1” **from the line 83 (if I remember correctly the line number).

On a project ported from 4.23 to 4.25.0, on Oculus Quest when loading a map, I’ve got the following ensure condition failing:

if (PrimitiveSceneInfo->NeedsReflectionCaptureUpdate())
{
// mobile should not have any outstanding reflection capture update requests at this point
**ensure(Scene->GetShadingPath() != EShadingPath::Mobile);
...]**

It’s in Renderer/Private/SceneVisibility.cpp:2098, inside the ComputeRelevance() method.
Does anyone have an idea what could be causing this in my project/map? Or is it an engine bug? Thanks for your help

Update: It’s happening on a specific map, trying to see what in it could be the cause of this.

Quoting myself, but if someone has this bug too (or a UE4 dev knows the answer), maybe this commit on 4.25 branch will fix it?
" Fixed crash caused by the dummy reflection capture uniform buffer being destroyed immediately after it was created."

Currently doing a full engine build in order to try and see (so with my computer it will take a few hours)… Will update this post after the test.

Update: now it fails on “IsValidLowLevelFast()” in LoadMap(). I did not manage to breakpoint using AndroidStudio so I will need to continue to dig in.
Update2: it seems that one of my AI Pawn blueprints placed in map got somehow corrupted with the update. It would fail in **FAsyncPackage::PostLoadObjects() **with if (!Object->IsReadyForAsyncPostLoad()) in the while loop pointing to an invalid memory address (even if IsValid() returns true for the pointer). Removing the instanced blueprint from the map and putting it in the map again seemed to solve the issue.

I am getting an error when i launch 4.25. It pops up with " The procedure entry point DXGIGetDebuginterface1 could not be located in the dynamic library dxgi.dll" I dont get this message when I launch 4.24 and have tried uninstalling and reinstalling the engine as well as re-downloaded C++ framework. i did get this DXGIGetDebugInterface1 function (dxgi1_3.h) - Win32 apps | Microsoft Learn as a starting point for the issue. I am on windows 7 and beleive that could be the problem. What I am really wondering is will this effect my project if i use 4.25 anyway ? or will it cause me issues later on ? or will it effect only the Microsoft App store stuff outside of the engine ? any possible solutions for this ?

Same Error here and only on 4.25. Since i’m also on Windows 7, i suspect it’s related to that somehow. Despite that it seems to work, though it would be nice to have this fixed.

Material layers seems not working properly in 4.25. It also constantly crashes when trying to switch material layer in the material instance.

ive the same problem … and in Blueprint Editor -> Add Component the Text3D Component is missing…
