Replace ALL materials from Revit in Unreal Studio

I can seem to make any progress replacing Revit materials in Unreal. Can anyone provide some help? I have tried this process (https://epicgames.app.box.com/v/Python-Examples/folder/47028699457) but it only does one material and there seems to be an error in the Replace Material Blutility. I have also tried this link. (The Journey from Revit to Unreal Studio | Feature Highlight | Unreal Studio - YouTube) and it does not exchange Revit instance materials with UE materials.
