Change Vehicle Color (C++ Template)

I created a Unreal project using C++ Vehicle template. I would like to change the color of the Vehicle on Begin Play. The specific material that I would like to change it’s color is the third material (element 2).

This is what I have inside BeginPlay function but it does not work.

UMaterialInstanceDynamic* myMaterial = UMaterialInstanceDynamic::Create(GetMesh()->GetMaterial(2), NULL);

	if (myMaterial)
		myMaterial->SetVectorParameterValue(FName(TEXT("BaseColor")), FLinearColor(0.0f, 0.0f, 0.0f));
		GetMesh()->SetMaterial(2, myMaterial);

Kindly help.
