Unreal Engine 4.20 Released!

Hi all,

This is my first post here and I am a total n00b to UE4.

However, I noticed a change that impacted the projectile’s behaviour. It seems they are no longer able to bounce at all.

Can anyone else check please? It is a real pain because I am actually working on a bouncing ball game

Thanks for your help guys, cheers.

sometimes when an update comes along, you have to re-compile your blueprints and re-set some properties and settings and such…

purrrfect timing guys, just finished up my motley crew of chars yesterday… thank you to all those that aren’t always in the spotlight, that just hunker down on sleepless nights to get the job done… i’m well aware of your efforts and contributions…

Hi,
I tried to add this line and remove list of folders that I added to public include paths before. Unfortunately, it doesn’t work.

[SPOILER]
public VRIKBodyRuntime(ReadOnlyTargetRules Target) : base(Target)
{
PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;

PublicIncludePaths.Add(Path.Combine(ModuleDirectory, “Public”));

PublicIncludePaths.AddRange(
new string] {
//“Runtime/AnimGraphRuntime/Public/BoneControllers”,
//“Runtime/Engine/Public/Animation”
}
);

PublicDependencyModuleNames.AddRange(
new string] {
“Core”,
“CoreUObject”,
“Engine”,
“InputCore”,
“HeadMountedDisplay”,
“AnimGraphRuntime”
}
);

PrivateDependencyModuleNames.AddRange(new string] { });
[/SPOILER]

If i uncomment these two lines in the build.cs, the plugin would compile successfully.

That line is only a template and not meant to include everything that you need. You would need to edit it to refer to the files that you need to include. As this doesn’t seem to be a bug, it may be best to make a separate forum topic or Answerhub for this particular issue so that it may be discussed by the community in detail. If you do believe this is a bug, feel free to provide a simple reproduction and submit a Bug Submission form

Hello,

If you believe this is a bug with the editor, please use our Bug Submission form to report the issue. When reporting the bug, you will need to provide more information however. Information to include would be the error that you’re receiving, when exactly this issue occurs, and what kind of things you’ve tried to fix it.

For some reason it just took like 10 mins for my firewall to pop up and ask me to allow the software to launch. Weird, but it’s working now.

Converted project from 4.18.3 to 4.20 today and am getting error during packaging, this project packages fine on 4.18.3. I saw someone post this error in the 4.20 preview but never saw a response any help would be very much appreciated. I did do a test on FPS template project and 4.20 worked fine I just don’t know what changed between versions to cause this to happen on my project.

Thank you!

Thanks for your answer. I started a whole new project in 4.20, there is nothing I took from the previous version. I compared the settings of the “old” and new BPs, they are absolutely the same.

Am I the only one not able to get a projectile to bounce?

Edit : Nevermind, I found the issue, my static mesh was not the root of my BP and, therefore, the projectile was not working as expected. Sorry for the mess

…
I didn’t really understant the purpose of this? Could you elaborate?

From my understanding it allows you to make gameplay tag containers only allow selection of tags in a specific subsection. Like weapon tags HAVE to start with Equipment.Weapon etc.

Hey guys, I downloaded 4.20, installed and lauched the Games Launcher but there is no button to install UR 4.20, just the orange Launch button for 4.17 and 4.19. How do I install 4.20?

Click on the Plus sign next to engine versions. Select 4.20 for the new launcher item.

Edit:
I found the WinX and WinY setting for each node so it works under fullscreen mode to put in different monitors.
Just if I want to set lower the window size and put all the nodes on one screen for testing, still have no idea.

Tried the nDisplay XD It’s a great feature! Looking forward for the beta release I’m trying it on one PC, and a problem currently is that it’s fullscreen by default, so if I have several monitors on one PC I have no idea how to move the different node screens to different monitors…

Not seeing a plus sign anywhere, or in the pulldown…see pic

You need to go to your library

You need to go to your library

And apparently how to upload images. Thanks Kvogler, for the assist

New: Scripted Extensions for Actor and Content Browser Context Menu Easily create in-context tools and workflow enhancements without writing a line of code by extending the context menus for Actors and Content Assets in the Browser using Blueprint Utilities, or Blutilities.

• Create a new Blutility using one of the new parent classes - AssetActionUtility (for Content Browser extensions) or ActorActionUtility (for Actor extensions).
• You can specify what types of Actors or Assets the actions apply to with the GetSupportedClass function.
• Add logic in events (or functions) with no return value, marking them as “Call In Editor” so they show up in the context menu, and a pop-up dialog will display when the event is triggered to fill in values for any parameters you define on your events

I can’t get this^ to do anything, following the instructions in the release notes.

1. I enable the Editor Scripting Utilities plugin, restart the editor
2. Make a blueprint of class ActorActionUtility (or AssetActionUtility)
3. Make a function or event in it with Call In Editor = true
4. Override the GetSupportedClass function (though it seems like thats optional)
5. Right click on a supported actor (or asset) - nothing?

Am I misunderstanding “Context Menu”?

So… apparently UHT is appending search paths instead of effectively “search” directories for include headers now.
Then we can omit any directory listed in PublicIncludePaths… But never omit any sub directory within them.

If a plugin’s directory path is added to PIP, for example:

PublicIncludePaths.Add( Path.Combine( ModuleDirectory, "Public" ) );

And we have a header within:

Path.Combine( ModuleDirectory, "Public/folderA/folderB" );

Now we have to specify the path in full below the ending directory of PIP (“Public/” in this case):

#include "**folderA/folderB/**MyHeader.h"

While previously we could just tell UHT to search for it within any PIP folders, like:

#include "MyHeader.h"

---

Fine, I think it’s fair and logic change… but annoying headache fix for soooo many #include directives I have to fix now =

I saw that mentioned a while ago in the commits, they were getting more include paths than some compilers could handle and decided to cut everything off at the Public folders to fix it

@Zeblote

I saw that mentioned a while ago in the commits, they were getting more include paths than some compilers could handle and decided to cut everything off at the Public folders to fix it

The problem is that if you place the engine source in a really deep path (C:\Development\GameEngines\UnrealEngine4\Latest\Engine…) then when compiler tries to compile source code, UBT will add all the include paths to a .response file used as input by the compiler. The max .response file for Windows (when compiling with symbol information) is 64K. Having the really long explicit path to all include folders in the .response file can easily cause it to exceed 64K in size. Having a shallow path (C:\UE4\Engine…) will prevent this, but not everyone has things set up that way. So now, instead of adding all sub-folders for a module/plugin to the .response file as an include path, UBT only adds “Classes” and “Public” folders and you have to modify the #include statement to specify the rest of the path to your .h file.

Ok, I am crazy or Niagara makes some basic stuff super time consuming? To create a simple particle with 3 emitter you need:

• Create a Niagara System
• Create 3 Niagara Emitters
• Add the 3 Niagara Emitters inside the Niagara System

And if I need to add 1 more Emitter I need create another emitter outside the Niagara System and Add it to the the System.

Add a way to create Emitter inside the Niagara System that go inside the Niagara System folder. Them you create a Niagara System and add 3 emitters inside the system.
