This doc is not useful. [https://docs.unrealengine.com/en-US/…ain/index.html](https://docs.unrealengine.com/en-US/Platforms/Linux/NativeToolchain/index.html)

Is there somewhere we can suggest corrections?

For example with the GetWorldTimerManager at [https://docs.unrealengine.com/en-US/…ger/index.html](https://docs.unrealengine.com/en-US/API/Runtime/Engine/GameFramework/AActor/GetWorldTimerManager/index.html) is says the include is #include “GameFramework/Actor.h” but you actually need to #include “TimerManager.h” to use it.

Easy one here, and not high priority, but still important I would think:

In “Archviz Interior Rendering” page, under “Samples and Tutorials \> Engine Feature Examples”, there’s a typo of the label of the ray tracing quality switch replace node. The label of the actual node is, I think, “RayTracingQualitySwitchReplace”, while this page has two instances of it typed as “RayTracingQualityReplaceSwitch” in the following location:

> **[Archviz Interior Rendering](https://docs.unrealengine.com/4.27/en-US/Resources/Showcases/ArchVisInterior/)**

Hello,

A lot of the language throughout the documentation uses masculine pronouns by default. For example this passage from [Exposing C++ to Blueprints Visual Scripting in Unreal Engine | Unreal Engine 5.2 Documentation](https://docs.unrealengine.com/en-US/Engine/Blueprints/TechnicalGuide/Guidelines/index.html)

[]  
At Epic, a lot of the workflow is that content creators will make a very complex Blueprint, and a programmer can see how he can compress a lot of that work into C++ by coding a new Blueprint node, so he moves that chunk of functionality into a new C++ function.  
[/]

It would be neat if we could change the pronouns in the documentation to use the more inclusive “they” where appropriate, or at least have a more even mix.

Thanks 🙂

The right side has the nav for contents of the current doc page / section in a little hovering window. In Firefox 79.0, it’s covering lots of the table text in the Sky Atmosphere Reference page for Console Commands, and is likely doing it on other pages if it’s working like that on other pages.

> **[Sky Atmosphere Reference](https://docs.unrealengine.com/4.27/en-US/BuildingWorlds/FogEffects/SkyAtmosphere/Reference/)**
>
> A reference page for the settings and properties used by the Sky Atmosphere system to create physically-based sky and atmosphere renderings in UE4.

I cannot read the text descriptions of settings and such easily enough. I’ll attempt to go to the same page in Edge and Chrome.

The Unreal Engine C++ API has many “weak” design choices i.e. ways the API allows being used that are incorrect. Case in point how “CreateDefaultSubobject” must ONLY be called from within a constructor but this is in no way of being enforced by the compiler due to the design.

If a software design choice means the software expresses MANY incorrect possible uses that the compiler will not be able to detect this increases the burden and cost on everything and everyone downstream. Even if a mistake is not made the cost of testing and uncertainty is still increased regardless.

Improving the documentation for the C++ API regarding critical programming theory for the engine is seriously needed and requires an expert on the architecture and workings of the engine in order to write it ( not another “beginners guide” by dummies for dummies please! ).

The translation of the Chinese version is not very good. In many places, the semantics are impractical, or the sentences are repeated, and some polysemous words are incorrectly translated. It feels like machine translation. I hope it can be optimized manually.

That is the least issue but I thought of informing you.  
Here:  
[https://docs.unrealengine.com/en-US/…ity/index.html](https://docs.unrealengine.com/en-US/Engine/Actors/Mobility/index.html)  
In the table describing mobility types, you have a typo.  
It states: “Not, however, that their Materials can still be animated.” while it perhaps should be: “Note, however, (…)”.  
But I am not a native speaker so perhaps it is some structure I cannot understand, but probably no.

In the Behaviour Tree Quick Start Guide, Section 5 Step 7 shows a Blueprint setup that’s impossible since it has two Patrol Location variables. When you try to set it up that way, you get an error that says “PatrolLocation is in use by another variable or function!” If there’s a way to make this work, it’s not described in the tutorial.

Hi, in the Automation Spec page ([https://docs.unrealengine.com/en-US/…pec/index.html](https://docs.unrealengine.com/en-US/Programming/Automation/AutomationSpec/index.html)), inside **BeforeEach and AfterEach** feature description, at the second example I think that:

```auto

BeforeEach([this]()
{
    RunOrder = TEXT("B");
});

```

Should be changed to (note the +):

```auto

BeforeEach([this]()
{
    RunOrder **+** = TEXT("B");
});

```

Because after it, the test checks if RunOrder is equal to “AB”, but it’s “B” instead.
