Unreal Engine 4.24 Released!

[blackerl]

in 4.24 release, New: Network Engine Test Suite You can create a network test by extending AFunctionalNetTest, then create steps for that test by extending UFunctionalTestStep for each one. Each test step must be designated as a Server or Client step, then added to the Test. You can then run a test by placing it in a level.

where can I find AFunctionalNetTest or UFunctionalTestStep?
I cannot find any sample project or classes in engine source.

I truly dislike new collections display system. I am constantly selecting assets from the collections and CB (rest of the project).
Now i have to first switch to CB or collection, then select the asset i need. Granted, it is just one more click, but it is very annoying when forced to constantly use it.
What was wrong with the old system where we could see both Content browser AND Collections? Can i have it back?

We are still trying to find the root of the issue but it seems to be the engine, we have tired testing outside the editor on a packaged build and the issue is still there, there seems to be a traffic issue in 4.24 as all our multicasts which aren’t set to relevant are just skipped, let’s hope 4.24.1 fixes this issue.

Have you solved your problems? I seem to be having traffic issues too, i have been spending a lot of time hunting down the problems between server->client. I cast to player controllers from the game mode to trigger events on each controller and im getting a lot of events just not triggering… seems making some reliable will work, not always.

All worked perfectly fine in 4.22, I might go back

It seems that Landscape with layers does not return Physical Material from trace hit. I have a project in 4.23, and there landscape returns Physical Material appropriate to trace hit location. However, in 4.24 the trace hits Landscape and it is identified correctly, but the Physical Material is always None.

Here It’s returning only the Default sound, ignoring all footsteps switch that was working 100% on previous versions.
I think this change made on the Landscape layer construction just broke the Phys material system.
Sadly I can’t get back to the previous versions with my project, because somehow my project just stop working on 4.23 and 4.22 from no reason, And the only solution I found was to convert the project to 4.24 version. It’s working fine, excluding The Footstep switch system.

I have problem with 4.24 using Virtual Texture crash the Engine and also try to compile 55000 compiling shaders

No it seems to be related to the engine it seems worse in the editor than a packaged project, I did report it as a issue to epic but haven’t had time to give them more info, the more people that report it the faster it will get fixed I hope haha :).

I have a “generic type” which I use to insert and replicate arrays inside of arrays/maps/sets…
Maybe I should convert it to a plugin (extract from project sources) and upload to GitHub, I always forget to do that *been busy

That looks handy how does it know which variable it setting and returning?

That looks handy how does it know which variable it setting and returning?

The “set” node gets type of input wildcard.
The “get” node uses Autocasting flag.
In C++ it’s just operators overloading.

For those still having issues with compiling Chaos for 4.24 please give this a try:

Compile it with this in the UE4Editor.Target.cs:

bCompileChaos = true;
bUseChaos = true;

Instead of:

bCompileChaos = true;

[anonymous_user_2709d010]

Is there a bug report for the broken landscape / physicsmaterial problem? I mean nevermind the crashes that 4.24 apparently shows but without that fixed I am stuck with 4.22

When it finished compiling was Chaos there?

[codewing]

[USER=“1062093”] Z[/USER] It successfully compiles the engine, thanks!

When running the code though the geometry collections make the engine crash. Is there something to do when migrating from 4.23.1 to 4.24.1?
I’ve also added

bUseCustomSceneQueries = true;

because it was necessary in 4.23.1 is it still?

It didn’t come ok for me. When running the Chaos demo, multiple asserts happen, nothing happens when you get to the switches during the level… it is a completely different history if you try 4.23 where the demo does work as expected. I am definitely inclined on not trying out the feature as it is, it is just too much of a time waste compiling the engine to not get the product working as expected, as far as Chaos feature is concerned.

[MothDoctor]

Don’t waste time on Chaos in 4.24. I have crashes on player movement (player capsule moving over the landscape) and tons of ensure hits.
Chaos is a mess

[Geodav]

BUG
just in case it hasn’t been reported, using “Force Delete” freezes the engine version 4.24.1 , to layz to try and search this forum tbh

[acxsasx]

Anyone else seeing long delays after pressing Play in selected viewport after updating to 4.24.1 (built from source)?

I am using dedicated server with 3 players.

1. Press Play
2. Wait 3 seconds
3. Viewport goes black
4. Wait 10 seconds <–This used to be a hardly any time in 4.22.3
5. Start to see graphics

Probably it is due to garbage cleanup taking too long to finish.

@MaximeDupart

Answering partially to what i noticed: there’s a new behaviour for Nvidia GPU owners, while previous engine version were not impacted by nvidia control panel settings (i had vsync forced ‘on’, yet my editor framerate was at 120fps).

From 4.24 Nvidia control panel settings are effective in editor viewports, as well as PIE.

I’ll see if it fixes my Editor crashes, but it seems i was forcing triple buffering and vsync in editor.

not sure if this going work here, but worth of give it a try
thanks for sharing, the editor random crashes was driving me crazy

[illYay]

This fix broke BeginOverlap events not firing at all if objects are initially overlapping on startup. I end up getting issues where OverlapEnd events are called when my character moves out of an Overlap event but the OverlapBegin event was never fired.

https://github.com/EpicGames/UnrealE…dbc44eade26ba6

Not sure what the original issue was. World->HasBegunPlay() returns false until all actors have had BeginPlay called. I tried tracking the updates so they are deferred until after level load, but BeginPlay on each component gets fired before that. There would need to be some kind of PostBeginPlay function added to make this properly work.

Perhaps AreActorsInitialized() is a better check than HasBegunPlay()?

Ta-da, my Plastic SCM source control provider has been integrated by default in Unreal!

After the Git plugin, this is my second big plugin

Edit: although someone from Epic forgot to put my name in the list of community contributors, not sure who to bug for this…

WOW loved seeing it in unity, its my choice as well.

Ty for notify.
