Importing into Unreal was another issue for me as my models’ scales were tiny. I got in contact with Alec and he was able to help figure it out as a scale issue with the Maya file. I had to open the Maya files and go into:

This fixes the scale issue when importing into Unreal and my assets were now fine to scale and move within the scene. I made a new level just for my assets, to get them ready for the scene. It was tedious but I got all models textures imported and applied and ready for my version of the Taverns layout.
For the glass objects, I added these textures in Unreal, Example:
