Unfortunately, I ran into an issue when it came to importing the OBJ pebble archway from Maya into UE4. For some reason, it imported as an incomplete mesh (see above), no matter how I exported it.
I ended up having to use the school facilities to do this – it seemed like there was a problem with my at-home software. Once I did this, the mesh was fine, and I could continue onto texturing normally.
I was concerned, however, that it would take too long to export a series of different rocks for the landscape, so I decided to use the original pebble OBJ and scale and rotate it in various ways to create the rocks within the landscape design in UE4.
I also added the two sculpted and unwrapped background trees I had done, to add more life to the overall landscape:
