We were approached by a mobile app company to create a music festival in minecraft for an event they hosted in real life, for their clients who weren't able to attend the event in real life. We accepted the challenge, and were responsible for building the world, coding the infrastructure of the server capable of handling thousands of players. We coded a VJ system in-minecraft and designed a light show. We coded a system to synchronize the music played in real life with the in-game music. For the event were created multiple quality of life plugins, plugins for cosmetics, player-interaction. At the end, the server hosted more than 10 000 unique players on a period of 4 days.
