Hello, In my application I receive materials info by network then I need to create a material with it. so far I create the material in the code bu I have no Idea about how to add roughness texture + intensity, metalness texure + intensity, normal map …
here is the code that I wrote create the material.

struct MaterialMetha
{
	bool side;
	bool transparent;
	float opacity;
	FString map;
	FColor color;
	FString roughnessMap;
	float roughness;
	FString metalnessMap ;
	float metalness;
	FString emissiveMap;
	FColor emissive;
	float emissiveIntensity;
	FString normalMap;
};

bool AShapeGenerator::GenerateMaterial(FString id, MaterialMetha metha)
{
	FString name = FString(TEXT("Material_")) + id;
	FString path = FString(TEXT("/Game/Material/Generated/"));
	FString packageName = path + name;

	UPackage * package = CreatePackage(*packageName);
	UMaterial* mat = NewObject<UMaterial>(package, FName(*name), RF_Public | RF_Standalone);

	mat->AddToRoot();
#if WITH_EDITOR
	mat->PreEditChange(nullptr);
	mat->PostEditChange();
#endif
	FAssetRegistryModule::AssetCreated(mat);
	package->FullyLoad();
	package->SetDirtyFlag(true);
	//mat->Set
	return true;
}

when I send the material by network It will appear with unreal default value on the editor, what I want to do is fill it with the value from MaterialMetha structure.
Thanks for you time.
