Postoffice has shared a glimpse at their new Crowd and Stadium Tool. The tool is said to allow artist to create new crowd looks on the fly using procedurally generated clothing. It lets users customize age, gender, flags, props, stewards, press, and more.
"Build stadiums in realtime with an endless array of tweakable options. Great for advertising, series or feature film projects. With the Euro Cup and Olympic games coming up this tool will allow brands and ad agencies to create stunning crowd shots for their ads. All Olympic / Euro cup countries are pre-programmed and ready to go," wrote the team.
At the moment the team is not licensing the tool, you can contact to see if they can help you with your project.
