Cannot open include file: 'FbxImporter.h': No such file or directory

Hello,
I’m trying to use the built in FBX importer of UE4. For this, what I seem to need is FbxImporter.h. However, when I’m trying to include it, I’m getting this error :

Cannot open include file: 'FbxImporter.h': No such file or directory

Here is my Build.cs file :

// Copyright 1998-2016 Epic Games, Inc. All Rights Reserved.

using UnrealBuildTool;

public class ImportIntoLevel : ModuleRules
{
	public ImportIntoLevel(TargetInfo Target)
	{
		
		PublicIncludePaths.AddRange(
			new string[] {
				"ImportIntoLevel/Public",
                "Editor/UnrealEd/Public"
				// ... add public include paths required here ...
			}
			);
				
		
		PrivateIncludePaths.AddRange(
			new string[] {
				"ImportIntoLevel/Private",
                "Editor/UnrealEd/Private"
				// ... add other private include paths required here ...
			}
			);
			
		
		PublicDependencyModuleNames.AddRange(
			new string[]
			{
				"Core",
                "CoreUObject",
                "Engine",
                "InputCore",
				"Projects",
                "UnrealEd",
                "Networking",
                "Sockets"
				// ... add other public dependencies that you statically link with here ...
			}
			);
			
		
		PrivateDependencyModuleNames.AddRange(
			new string[]
			{
				"Projects",
				"InputCore",
				"UnrealEd",
				"LevelEditor",
				"CoreUObject",
				"Engine",
				"Slate",
				"SlateCore"
				// ... add private dependencies that you statically link with here ...	
			}
			);

        AddEngineThirdPartyPrivateStaticDependencies(Target,
            "FBX"
        );


        DynamicallyLoadedModuleNames.AddRange(
			new string[]
			{
				// ... add any modules that your module loads dynamically here ...
			}
			);
	}
}

I followed the .Build.cs found in the UE4 code where they needed FbxImporter.h, so I’ve got a similar Build.cs file, but it’s not working. Any idea ?

EDIT : here is what I get when I try to include the absolute path to the file :

You should see that file in “Engine\Source\Editor\UnrealEd\Private”. If you see the file you can try adding the absolute path to the include line. And if that works, try "#include “/Editor/UnrealEd/Private/FbxImporter.h”

That seemed promising, but it’s now working. I’ve updated my question and put the errors I get with your solution. When I try to include the whole absolute path (i.e #include "C:/Program Files/Epic Games/4.12/Engine/Source/Editor/UnrealEd/Private/FbxImporter.h") I get this whole load of errors that come from the .h file. Am I missing something? Maybe in my Build.cs ? I didn’t touch it compared to what’s in my original question.

Those errors are due to the FbxImporter.h not finding the fbxsdk.h.
If you use the GitHub build of the unreal version you are using, it should find the library and thus ending your errors, though i’m not sure.

Yup, this solved my issue ! Just using the built-from-source UE4 version instead of the launcher one. Thank you !
