I guys will welcome to this new lecture and this lecture we wanted to explore the null object and see
how we can use it.
What's the benefit and what are the methods that are mainly used for object.
Let's take a simple example.
And this composition I have four squares that are rotating on their own anchor points.
If you select them you see that the rotation is happening on their own and at that point.
Now what I would like to do is to rotate the four of them in the middle of the composition.
So they rotate on their own and could point and then they rotate around the position center as soon
as you have two or more layers that you want to animate exactly in the same way.
Think about the object it will help you a lot.
In this case we have four letters that we want to animate in the middle of the composition.
It means one single anchor point.
And of course null objects are the thing to use here.
Let's create a null object.
We come to layer new and click on an object an object here is created.
Actually this object has nothing that has no colors and it would not render like we said and the anchor
point is on the upper left column.
You're not just a folder that's great for you.
And inside this folder you have your null free.
This is the one.
It has an internal numeric system that will number or not 0 1 2 3 4 or whatever.
Now I will come to all the layers and use of course the printing to print them to the non-theory.
And obviously now if you listen carefully to the lecture about parenting you know very well.
If I move or rotate or scale the knol it will also do the same for the other four layers.
I will open for example rotation keyframe the rotation in the beginning go to 4 seconds to make it slow
and nice and give it a two here two rotations if you run your animation now all your legs will be rotating
on it themselves and also rotating on the anchor point of the null object.
This is the power of the null object.
Also you can click on the null object and move it around.
And that you still maintain the animation of course for everything.
So actually after creating the null object you are back to parenting and how to use parenting as simple
as this fun.
Let's go to another animation here.
We have several layers.
Some of them are shaped some of them are text and you want them to turn all together and then shrink
a bit down scale down and then move out.
How do we do this.
Any mission symbol or any mission by the way.
Let's go to new and create a null object again.
The Null Object is the center here.
That's very fine.
We select all our layers and we will weep for parenting.
You do you have them now.
Let's open the scale position and maybe the rotation of the null object.
So the first thing I want to do is to keyframe descale and after some time let's bring this one here.
After a few seconds just make it 80 percent real do.
So they get smaller even more 60 percent call and you know this how they are all getting done.
Of course we're talking about parenting here.
But also we are demonstrating how easy is it to use the null object to move the five or six letters
that we have.
I will keyframe the position I would keyframe the rotation here come a few seconds or a few frames and
turn them minus 90 degree at school.
Keyframe again the position was necessary to keep them in the beginning but nevertheless come to one
second.
Now hold the anchor point press shift and move it on this side and then after two seconds just move
it to the outside.
OK.
That's a sample of how you can use the null object to any.
Similarly as you are actually grouping them.
Let's play our animation.
And it's pretty nice.
Pretty cool.
Not this that this animation would have been almost impossible without the null object.
This is all about the null object for now and we are going to use it mainly to create some superb animation.
The power of use of the object will become more obvious for you when we are using a 3-D animation and
we are doing motion tracking.
This is all explained in the course later on.
Thanks very much for listening.
I'll see you in the next lecture.
