I passed the design off to the tech artists, and they began constructing the full Costume Party experience. But it wasn't all easy... We ran into a few complications!
We had limited space for art materials within each effect. This caused us to make artistic sacrifices to the quality of some of the art pieces, and we had to swap out some parts for new ones. Luckily we were able to come out with 12 costume items that looked great in game.
Some of the costume pieces were causing glitches when paired with other items. Through extensive testing, we were able to identify and alter any pairings that caused glitchy facial distortions.
Costume Party was one of the most-used interactive effects on real-time calls for Messenger!
