tank and I just realized how fucking STRONG the boob physic is on mother gothel like wtf
Ariel’s weren’t bad during the famous wave-splash scene either.
That would be Secondary Animation (Secondary motion). In 3d the primary animation would be done by one person or group of people and then refined to get every intricacy down. In this case boob jiggles. Attached to the bones under the 3d model usually a muscle rig would be added and a even a slight cloth modifier to show stretching of the muscle underneath the skin.
In 2d of course it would have to be hand drawn. Also in animation, Ive learned that there is no coincidence and things are either overlooked or done on purpose. So when you see all those Disney sex references, they are mostly true.
Side note:When I was attending school for animation I went and saw The Watchmen. Dr. Manhattan was a complete 3d model with primary animation taken from the actors motion capture markers. However he was naked. and when he walked his butt shook and his frank and beans swayed around. We had a discussion in class with our teacher and he said it was up to a team for secondary motion (I mean look at the credits, tons of animators) and probably a persons sole duty to make sure Dr. Manhattans junk moved correctly. Haha.
