There is a typo on this page: [Placing Material Expressions and Functions in Unreal Engine | Unreal Engine 5.2 Documentation](https://docs.unrealengine.com/en-US/RenderingAndGraphics/Materials/Editor/index.html)

I know it has been brought up a few times, but I think it would be great to make the source of the documentation available on github, so the community can fix errors like this and submit PRs. It is much more streamlined than coming to a forum, and writing a comment about it…

UMG Designer Quickstart docs appear to be out of date. UI does not match 4.26. Difficult to proceed. Looks like docs are 4.23 and Blueprint editor has changed significantly. Any ref to new UI?

Hi Epic Games, I was loking at some images on the [docs.unrealengine.com](http://docs.unrealengine.com) website and when I come out of image fullscreen I cannot seem to scroll up and down on the page. I dont know if anybody else is getting this issue but the only way to get out of ir is to refresh the page.

The documentation is misleading or outdated. In the last code example it states that “// Unreal Header Tool (UHT) will create GetMySparseClassData automatically.” which UHT doesn’t actually do. The documentation also doesn’t specify whether classes with SparseData actually create the sparse data at runtime, which is what I assumed when I read the documentation. I ended up having to use “GetClass()-\>GetOrCreateSparseClassData()” which does exactly what I thought the UHT “GetMySparseClassData” would do. Some clarification is needed.

Hi,

I don’t know any other right place where I have to note and I’m newcomer in Unreal engine and If I’m wrong just ignore my post. 🙂

It seems like, on the documentation [Player-Controlled Cameras | Unreal Engine Documentation](https://docs.unrealengine.com/en-US/ProgrammingAndScripting/ProgrammingWithCPP/CPPTutorials/PlayerCamera/index.html) in the First step code isn’t working. We need to add the next lines code:

```auto

#include "Camera/CameraComponent.h"
#include "GameFramework/SpringArmComponent.h"

```

It should look like below:

```auto

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/Pawn.h"
#include "Camera/CameraComponent.h"
#include "GameFramework/SpringArmComponent.h"
#include "PawnWithCamera.generated.h"

UCLASS()
class FPSPROJECT_API APawnWithCamera : public APawn
{

```

Please, fix the documentation.

Thank you.

Hey Echo\_Four, I could have been more specific. The code samples appear to have been HTML encoded. This is a declaration that compiles:

Hi there, you might want to double-check this, but I think the module name is incorrect on this page:

[https://docs.unrealengine.com/en-US/…ule/index.html](https://docs.unrealengine.com/en-US/API/Runtime/HttpServer/FHttpServerModule/index.html)

It is not HttpServer. It is HTTPServer, like the folder in the include file. HttpServer would compile for me but not package. HTTPServer packaged.

If you look in the file HttpServer.Build.cs, you’ll see the module declared: `public class HTTPServer : ModuleRules`. It’s a mixed case aerial turkey-romp, but the packager needs the class name.
