Animating nine girls dancing onstage is hard work. It’s why the Love Live! anime usually reserves 2D animation for moments with three girls or less, and has 3DCG do the grunt work when showing the entire ensemble. One consequence of this is that, throughout the original Love Live! anime’s run (as well as the music videos made prior to the anime), the transition to 2D and 3D would look fairly awkward. However, what I’ve noticed from the first and especially the second season Love Live! Sunshine!! is that its CG portions are a lot better at removing the kind of “plastic” feel from the characters.

While I think the CG has just generally gotten higher in quality, making the models just look better overall, one major change I noticed that I think goes an extra long way in smoothing the switch between 2D and 3D is how the eyes are portrayed. In the 2D sequences, the girls’ eyes have a kind of soft glow that gives them an appearance of liveliness, of soul and depth. In the two Love Live! openings, when the CG switches occur, their expressions just look much blander, as if they’re puppets in the shape of the characters. With Love Live! Sunshine!!, the girls of Aqours have very pronounced and bright eyes even in the CG portions of their performances. In the second Sunshine!! season, the performance scenes keep the angles of backgrounds more consistent to make the transitions much less jarring.

This reminds me of a talk I went to at Japan Society in New York City, where anime writer Sato Dai (Eureka Seven, Battle Spirits) was giving a presentation on 3DCG in anime. One of the things he mentioned was that capturing “kawaii” in 3DCG was a major step in its implementation in Japanese animation, and I think we’re seeing the fruits of it. If the appeal of characters approaches appealing to the inner feelings of its viewers, then having eyes that appear to reciprocate emotionally would serve that direction quite well.
