As part of the UE5 launch I was asked to redesign the Unreal Engine Content Examples project. This involved designing and building a more flexible room / display blueprint and swapping out all 50+ levels with the new design. Both the displays and the room use 9 slice technique (although as it's 3D I guess it's closer to 27 slice :P) to create an easily scalable space and display. I used a custom editor utility script to swap out the displays and rooms with the new one which saved a huge amount of time.
Thanks to JS for help with art direction!
