With the features currently available in the app, it is possible to load both regular badges and the new event badges in the same way. The only thing that matters is the order in which they are loaded.
If you have any other questions or need further clarification, please don't hesitate to ask through this channel.
The application automatically prepares a .zip file containing all emotes and badges, rescaled to the dimensions required by the platforms where they will be used. Final files, ready to be delivered to the client.
