As soon as the Spark AR software became available it was inevitable that I would try and make something like this. The model itself was imported using the Sketchfab integration, but it required modifying it to separate the jaw using Blender to then work with the mouth effect.
Combining my favourite anime with the face tracking feature, I was able to build an effect that let you control the movement of the Eva. As well as having this it could react to your mouth and would play the Beast Mode roar from the series.
I attempted to make a kind of parallax, with some layered city buildings behind the Eva moving with or against the rotation of the head at different speeds.
Out of the series of Evangelion Unit effects I made this was by far the most popular.
