Lesson #9 Follow Through and Overlapping


I had quite busy days during the last month but I finally find the time to create a new lesson … ready to learn how to “section” your character? 🙂

Follow Through and Overlapping RECAP

The principles of follow-through and overlapping will help you a lot to refine your animation and make it more realistic and fluid

Behind this principle there’s a simple rule:follow_through01.png

Follow-through is the principle that a parts of the body follows the movement of an other part (the leading one), with a bit of delay

Example: when you have a stop a part stop first and an other one has a delay, so it will stop in a different timeFollow_Through02.gif

Overlapping action is the principle that some parts have different timing or speed compared to other parts, so they overlap the main actionFollow_Through03.gif

– We can use them to delay each parts of the body:

  • for human characters we can apply this principles on several parts: arms, neck and head, upper chest, legs, hair…

Follow_Through04

All this parts will move with a bit of delay compared to the main part of the body that leads the movement, they are offsetted and they OVERLAP the ACTION

  • for animals or anthropomorphic characters we can also have some different elements like long ears or tails to animate using this principles

Is quite simple, if you analyze for one second the movement… you should be able to recognize which part leads the action, here some examples:


When you know which part leads, you just have to delay the other parts

Don’t forget that… at the beginning of the action, this parts react to the movement of the leading one, by moving in the opposite direction!

In this example we have a simple arm movementFollow_Through05.gif

the shoulder and the upper part of the arm lead the movement, so when they start to move forward, the forearm reacts moving in the opposite direction, then we have the same reaction on the wrist and the fingers

When the leading part arrives to a stop, the forearm, the wrist and the fingers stop with a delay and different timing

So the arm and shoulder drag the lower part of the arm and during this movements you can also break some joints and use some deformers to emphasize the delay and the arcs

So… at first animate the upper part, the leading one, then the lower arm, then the wrist and last…add the fingers animation

You can also delay each finger from the others or even the single parts of the finger

To complete the movement you can add a…follow_through20.png

to avoid a sudden stop, keeping a slight bit of motion for all this parts for more frames

or add a…follow_through21.pngafter the stop all this parts go back and forth for few times, always decreasing the motion, keeping the delay between a part and an other. The leading part could have just a small and short settle, and the other parts a longer settle

or just the…

In this Lesson I explain more in detail Moving Hold and Settle


How to manage follow through, overlapping action, moving hold and settle depends on:

  • -the type and speed of the motion
  • -the length and weight of the parts that follow the movement

 

An other situation where you need to apply this principles is when your character has some cloths like: an hat, a scarf, a coat, a skirt, etc…

This elements will have the follow through and the overlap just like the body parts. The body movement drags this elements and they will react in different ways, depending on the type of cloths, the material’s weight and the speed of the movement


A good way to manage and animate parts with follow-through and overlap is to visualize the body as sections

In this way will be more easy and fast for you to manage all the delays 😉

Also a tail can be visually split in section:follow_through27follow_through28

the upper part would lead the movement, moving first, the second one would follow this movement, the third one would follow the second one and so on…Follow_Through08.gif

Compared to the main section, the second one has a delay of 1 frame, the third one a delay of 2 frames, the forth one of 3 frames and so on….

in this way your movement would result smooth and realistic! 😉Follow_Through09.gif

Do the same for objects or parts of the character and the practice will help you to naturally apply this principle in the right way!
