MaterialInterface which is a base class for other classes (such as UMaterialInstanceDynamic) is not being exported which causes compiler errors when a user attempts to access the functions of this class. Specifically, GetWidth and GetHeight are having this issue.
1. Create a new project
2. Add a C++ class of the type Actor
3. Below "virtual void Tick( float DeltaSeconds ) override;" (Line 21) in MyActor.h, add "UMaterialInstanceDynamic* DynamicInstance;"
4. Below "PrimaryActorTick.bCanEverTick = true;" (Line 11) in MyActor.cpp add "DynamicInstance = CreateDefaultSubobject<UMaterialInstanceDynamic>(TEXT("DynamicInstance"));"
5. Below "Super::BeginPlay(); (Line 18) in MyActor.cpp add "Height = DynamicInstance->GetHeight();"
6. Attempt to compile the project
Result: Compiler errors are given due to the function in step 5 not being accessible
Expected: The compiling should complete without any errors
