Be a part of movement designer Tim Lucke as he walks by means of his character animation course of in Adobe After Results. He’ll use expression controls, monitor mattes, and character rigging to carry an animated intro to life!
On this lesson Tim will undergo expression controls to indicate you easy methods to add wiggle expressions in After Results for a cute, easy animation. To study extra, you may watch the entire free After Results course Grasp Movement Design – Dynamic Character Animation in After Results.
Add Wiggle Expressions in After Results
I will present you easy methods to add an Expression in After Results – a wiggle. I need the bubbles within the beaker to jiggle round, like a kind of chemical compound.
Place Properties
You possibly can see above that the layer Bubbles 1 pertains to the bubble with the sq. round it within the flask. We’ll add some place properties, and we’re not going separate the scale on this case.
When you hit Choice / Alt on the keyboard after which Place, you will see that the expression editor will seem to the correct of the layer. All you must do now could be sort wiggle, and that wants two properties:
- Frequency: How typically
- Amplitude: How a lot
What the values ought to be would possibly require slightly trial and error. I began at 10 and 10 however that was fairly erratic so I settled on 2 and 10 after taking part in it again.
Wiggle expressions are a very easy means of including slightly little bit of randomness to the animation, and all I needed to do was write one line of code.
Copying an Expression
Now we have one bubble and the expression, all we have to do is seize the expression and apply it to the opposite bubbles.
You possibly can right-click on the bubble layer and select Copy Expression Solely.
Then you may choose your different two bubble layers and paste that expression, after which by urgent E,E you will see these expressions now related to the opposite layers.
What’s additionally nice is that these different two wiggle expressions are literally utterly impartial and can generate its personal random numbers, so relative to one another there’s going to be random motion, which is what we wished.
One other Wiggle Instance
Rotation
On this instance we will take a look at including Wiggle with rotation.
Hit the stopwatch icon – circled above – after which add ‘Wiggle’ once more, however this time the frequency goes to be 4 instances per second. As that is rotation do not forget that we’re pondering in levels, so 360 levels is a full circle and we simply need this to rotate slightly bit so it must be delicate, so I’ve chosen 4 levels for amplitude.
I additionally need this to be slightly bit chunky, so I am going to introduce you to a different expression which is named Posterize Time.
Posterize Time
Posterize Time ought to all the time go on the highest, consider it like an adjustment layer. That is in frames per second and I solely need this to maneuver a really small quantity, so I’ve gone for 4 frames per second which supplies it a little bit of a kiddy vibe.
Copy Expression
As you probably did earlier than, you may then right-click to repeat the expression after which paste that to all the opposite letters within the phrase, and so they’ll all rotate barely in another way. Now we would like them to come out slightly.
Dad or mum to Null Layer
Go to Layer > New > Null Object in after which pop that in the midst of the phrase. Subsequent, you might want to mum or dad the opposite letter layers, and provides that null layer a reputation of something you want.
Be sure you lock the size in order that every thing strikes in unison and you are not making modifications to just one letter. You possibly can, in idea, have introduced all of the letters in as one piece however you are able to do a lot extra when you deal with every layer independently than you possibly can all collectively. We simply noticed that by including the wiggle expression in After Results to every one, however you may apply that to scale, and different actions too.
Conclusion
We hope you’ve got realized some new issues about After Results expressions, and specifically in regards to the After Results wiggle expression. It is a actually fast instrument to make use of that can assist you add animation simply to your video initiatives. Keep in mind, as soon as you’ve got created your expressions in After Results, you may copy and paste them to different layers to get the identical actions, however independently, so they will not look too uniform.
