Create Control Bus Mix Asset from within BP

I’ve dug around and found the FEditorFileUtils::SaveAssetAs() C++ utility function, which was really easy to put in a BP function library

In your MyGame.Build.Cs:

PrivateDependencyModuleNames.AddRange(new string[] { "UnrealEd" });

In your project create a new BP Function Library C++, with:

#include "FileHelpers.h"

...

UCLASS()
class UMyUtils : public UBlueprintFunctionLibrary
{
	GENERATED_BODY()

public:
	UFUNCTION(BlueprintCallable)
	static void SaveToDisk(UObject* Asset);
};

Then in the CPP it’s as simple as:

void UMyUtils ::SaveToDisk(UObject* Asset)
{
	TArray<UObject*> Assets;
	Assets.Add(Asset);
	TArray<UObject*> OutSavedAssets;
	FEditorFileUtils::SaveAssetsAs(Assets, OutSavedAssets);
}

It will produce a file save dialog and generally do what it says on the tin. How refreshing!
