>3d cars look better than 2d cars, even in an otherwise 2d show.

This is quite debatable, if you notice that the car is a 3D object, then something is already wrong.

It was a major consideration for Initial D, which is pretty much the definitive car anime. Animating movement in tandem with dynamic camera movement is very difficult (also why shows like Love Live use 3DCGI for dance scenes, and why Disney was using 3D elements in films like Beauty and the Beast) and modeling accurate vehicle physics in hand drawn animation is also difficult. It simply wouldn't have been viable without 3D animation.

Usually you can tell by the fact that nothing is wrong, since the 3D model is very consistent and on model. A hand-drawn car is usually not that.

The same could be said for a 3D human character, it's very consistent because it's a 3D model but it's horrible to look at.

Do you notice when Bluey characters are animated from 3D or 2D? The software they use allows to do 2D drawings from 3D animated models.

I have never seen Bluey but from the software you linked it is clear that it looks 2D because of how inconsistent the character looks at different angles, for example when you rotate the character the mouth changes position, the hands jump from one sprite to another, it's cel shading with a lot of 2D element on top, it works with simple animation but for anime I'm not optimistic.

His point, I believe: artistically interpreting the motion and shape of humans or objects with larger moving parts makes animation look more on-style.

But for "boring" rigid objects, there's less of this advantage; hence, the consistency benefits often are more important.

unless it's Miyazaki films - in which case most humans are intended to be lifeless rigid objects and every machines are to be lifelike animations (/s)

[Hamuko]

I've seen 3D animation where the people are still quite fluid and not awful to look at. Not as good as 2D animation but still pretty good and more than watchable.
