A company wanted me to design the assets that they primarily use for their booths they used when at conferences. Basically, it was creating a 3d booth for them to easily visualization the layout before going to the show. This way the person in charge of booth design can visually see how the booth will look and make any changes beforehand instead of scrambling before the doors open at the event.
After leaving the company, I decided to take those assets and go a few steps further when creating my Expo Hall Environment. Ended up making a full set of stands and parts that I found were the most common among the references I could find. Now the Expo Hall lives on in various digital marketplaces for others to create their own expo/conference for their company.
