Accessing Methods (eg GetHeight() ) of Class pointed at (eg UMediaTexture) fails?

Dear all,

I am new to C++ and it might be an easy question for you all professionals, but I am stuck somehow and are not moving forward anymore.

I would like to setup a blue print which takes a VideoTexture as Input, calculates the alpha based on chormakey calculations and returns as output the now change videoTexture.

So going step by step, I first setup the blueprint node like:


#include "ChromaKey.h"
#include "MediaTexture.h"


UMediaTexture* UChromaKey::CreateChromaKeyTexture(UMediaTexture* ChromaTexture) 
{
	uint32 VHeight = 0;
	uint32 VWidth = 0;
	// VHeight = ChromaTexture->GetHeight();
	// VWidth =  ChromaTexture->GetWidth();
	return ChromaTexture;
}

Which worked fine and the blueprint node shows up with the correct type of input / outputs.
When removing the comments of VHeight = … and Width = …

I receive a compiler error saying: .
Error C2039. “GetHeight” is not an element of “UMediaTexture”

My Header-File looks like:


#include "Kismet/BlueprintFunctionLibrary.h"
#include "MediaTexture.h"
#include "ChromaKey.generated.h"







…


UFUNCTION(BlueprintPure, meta = (DisplayName = "ChromaKey Conversion", CompactNodeTitle = "ChromaKey", Keywords = "Converts ChromaKey Texture"), Category = Game)
       static class UMediaTexture* CreateChromaKeyTexture(class UMediaTexture* ChromaTexture);



};

In my Build-File I have included 

PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "RHI", "RenderCore", "ShaderCore", "MediaAssets", "Media"});

What am I missing here ?

Any idea is welcome…

Thanks

Andreas

[EDIT]
No one any hint for me?

Figured it out:

Somehow the Header file showed up in the Visual Studio Explorer but when opening the file, MS states, that the file was not found.
After I setup a new project using the unreal source code, it now compiles without error.

I dont know what I did wrong in my first setup - but I somehow corrupted the installation :-(.
