Unreal Engine 4.18 Released!

Bug editing the Light Color of a SkyLight
Every time you double-click to open the colorpicker, the hsv value is loaded incorrectly - an offset is added.
(if value is 0, then this does not happen).

Steps to reproduce:
Drag SkyLight into scene.
Double-click Light color to open Color Picker. Change to non-zero value and save (V in HSV)
Double-click Light color to open Color Picker again Incorrect value shown…

You know that there has to be AH report in order for Epic even to start looking into your bug?!

[adigyran]

can you please explain, what happened with tango classes? I can`t see any mentions in patch-notes about it

Hey fellow Unreal Developers,

We have successfully upgraded our project to 4.18 with all the help of these transition guides from 4.15 to 4.18. However we have now stumbled upon a problem which I am not sure if some of you have encountered this and might have an idea how to tackle this.

We have excluded the following files from our version control server:

• .target
• .modules
• .pdb

We (programmers) compile the latest DLLs and push them the to the server so that the whole team have the latest C++ changes and can continue working with the new changes we make daily. The rest of the team (non-programmers) do not have Visual Studio installed and have not required to need it installed on their PC.

However with upgrade to 4.18 the project keeps asking to build the DLLs because files are missing and it might be build with an different engine version. This was not the case in 4.0 - 4.17.

I have created an answer topic with a new project in 4.18 so you can see the differences.

Is there any kind of world/enviroment collision with the clothes?

Hi,

I have encountered an trying to build a dedicated server for a 4.18 project. The engine was built from source, then a binary version was created from that.

My problem is the content of the “MyGame.Server.Target.cs” file located in the MyGame/Source folder.

I am following this guide: https://wiki.unrealengine.com/Dedica…ows_%26_Linux)

The guide suggests using the following lines:

using UnrealBuildTool;
using System.Collections.Generic;

public class MyGameServerTarget : TargetRules
{
public MyGameServerTarget(TargetInfo Target)
{
Type = TargetType.Server;
bUsesSteam = true;
}

// TargetRules interface.

public override bool GetSupportedPlatforms(ref List<UnrealTargetPlatform> OutPlatforms)
{
// It is valid for only server platforms
return UnrealBuildTool.UnrealBuildTool.GetAllServerPlatforms(ref OutPlatforms, false);
}

public override void SetupBinaries
(
TargetInfo Target, ref List<UEBuildBinaryConfiguration> OutBuildBinaryConfigurations,
ref List<string> OutExtraModuleNames
)
{
OutExtraModuleNames.Add("MyGame");
}
}

Now as far as I know that is outdated, so I changed it to this:

using UnrealBuildTool;
using System.Collections.Generic;
public class MyGameServerTarget : TargetRules
{
public MyGameServerTarget(TargetInfo Target) : base(Target)
{
Type = TargetType.Server;
bUsesSteam = true;
ExtraModuleNames.AddRange( new string] { "MyGame" } );
}

// TargetRules interface.

public override bool GetSupportedPlatforms(ref List<UnrealTargetPlatform> OutPlatforms)
{
// It is valid for only server platforms
return UnrealBuildTool.UnrealBuildTool.GetAllServerPlatforms(ref OutPlatforms, false);
}
}

However, upon generating the project files, I get the following error:

ERROR: c:\MyProjectPath\MyGame\Source\MyGameServer.Target.cs(22,36) : error CS0122: 'UnrealBuildTool.UnrealBuildTool' is inaccessible due to its protection level
ERROR: c:\MyProjectPath\MyGame\Source\MyGameServer.Target.cs(22,52) : error CS0117: 'UnrealBuildTool.UnrealBuildTool' does not contain a definition for 'GetAllServerPlatforms'
ERROR: UnrealBuildTool Exception: Unable to compile source files.

Does anyone know how to do this correctly?

Thanks!

I’ve this problem too, any suggestions ?

I wanted to point out that there is no PS4 devkit Firmware version 4.730.001, instead there is a devkit 4.730.011, is that the one you support? or should I go for the 4.740.001?

(Tagging @Kontur as well since he had the original question).

Follow the updated instructions on that page (the 4.17 should still be valid). If you are using anything newer than 4.14 - you don’t need to override GetSupportedPlatforms.

Your Build.cs should look exactly like this

using UnrealBuildTool;
using System.Collections.Generic;

[SupportedPlatforms(UnrealPlatformClass.Server)] // This line replaced the need for override GetSupportedPlatforms.
public class MyGameServerTarget : TargetRules
{
       public MyGameServerTarget(TargetInfo Target) : base(Target)
       {
        Type = TargetType.Server;
        ExtraModuleNames.Add("MyGame"); 
       }
}

Thank you very much ExtraLifeMatt, this has solved my!

Looks like on 4.18 shipping I get this crash right when I enter the game.

Fatal error!

Just tried on development and it works.

Ps how can I get logs on shipping version?

looks like tcp/udp plugins have to be activated in the project in order to run on shipping…even if we don’t need them

Anyone else noticing slow load times for large cooked packages (1GB+) ?

Between 4.16.3 and 4.18 I did some basic testing and our cooked game load times are 2x faster in 4.16.

Both Async and EDL enabled, shipping configuration. Pak file mode disabled. Tested both initial load time (non Cached) and successive load times (IO Cached) both on Physical and SSD drives.
It’s more noticeable on Physical drives but the factor of difference is the same.

I feel 4.18 is a lot slower than 4.16 and 4.17 in general. Not sure what they changed that causes this, but it’s definitely noticable. I probably have to downgrade to 4.17 again.

[anonymous_user_7d438cea]

4.18.1 will be in soon, so maybe before downgrading see if the slow still persist.

[BlackFangTech]

Anyone else getting really bad performance on this version compared to 4.17?

Seems great to me, especially compiling C++.

Any idea on the release date of 4.18.1? I am running 17.2 I feel I am in a good stable place with 4.17.2

[RVillani (Rod Villani)]

4.18 seems pretty stable for me. Worked a whole day without a single crash. Kind of simple project though, not many structs (the source of most of my crashes). Also, compiled ok. I haven’t noticed the performance issues. But I hope it is improved before I do. hahahaha

Should be soon… on github you can see they have TONS of fixes for 18.1… Should be good.
