For this project we imported pre-made assets from different locations into a single level/project in UE4. We then placed the assets into our level and connected everything to source control.
Note that I made nothing in this scene I just put everything in there:
Because I am still getting used to both Perforce and UE4, this project was kind of confusing for me and I am still not completely sure if I did everything correctly. I'm sure as the year progresses though the process will become much more comfortable.
