HammUEr, a Hammer/Worldcraft map importer for Unreal Engine

I am having an issue. I have done everything right I believe. When importing the .vmf the models appear with their textures but the brushes and displacements do not. The materials exist in Ue4 after importing with TextUEr . I’m using UE4 4.18.3 and Hammuer 1.8 Alpha for UE4 4.18.
