Unreal Engine projects seem to be getting bigger and bigger. Gone are the days of importing one Datasmith file through one Dataprep pipeline and doing some polish work for one presentation. Now, we are expected to have multiple high-fidelity buildings with intact metadata, occupying a high-fidelity city context, within a geographically correct country. This talk gives an overview of the increasing number of approaches to handling projects of this scale and keeping up to date with design changes as they happen.
