Newton

Newton is not an effect, and you won't find it in the Effects & Presets panel. You open it using the Newton command from the Composition menu.

I like how he acknowledges that modeling has very specific standards, and just because you dont meet then doesnt mean you cant be beautiful

Newton ignores the following layer types: audio layers, guide layers, 3D layers, and video-disabled layers.

When creating a scene in AE it is important to keep in mind that Newton doesn't look at layer pixels, it only interprets the shape/contour of a layer. For instance, precomp or footage layers will be interpreted as rectangles, no matter what they contain or represent. Every custom body shape must be created with masks, shapes, or text.

linear dampng gives some resistance to the bubble

Pin Objects Like A Tail

Yea I think it has something to with having separate nulls on the tail. So they are separate objects initially. Then have a script that connects them together to make a tail. Probably named "Connect Layers Pro"

What is AEMatic? Merge between Kinematic and Dynamics. Can still art direct while being affected by dynamics.

Kinematic Need keyframem from beginning to end. to have manual effect other wise it will result to dnamics..
