- [Voiceover] Animating clouds in Vue is very easy.
We just need to know in advance that
the atmosphere editor has its own rules
for dealing with creating key frames.
Most objects will respect the auto key frame state,
currently I have it disabled.
In the animation menu, auto key framing is disabled.
But whether or not that is on does not influence
how the atmosphere editor creates key framing,
because it has its own key frame option
that you can enable and disable.
So let's go into the atmosphere editor,
and we wanna go to, in this case, the clouds tab.
And there's a big button up here
and it's called forbid atmosphere animation.
If that's on, then you can change any values
that you want in here, and you will not
generate key frames.
If it is off, and you're at a non-zero
point in your timeline, then you will start
creating key frames.
And currently, because we changed our animation range,
I'm at a time index of five seconds.
If I make changes here now,
and the forbid button is off, then Vue is gonna think
that I want to create key frames.
For these parameters here, for the cloud wind,
I'm not gonna be key framing those.
I want those just to be a static value
over the course of the animation,
pushing the wind in a certain direction
at a certain speed, and morphing, or churning
at a certain rate.
So let's not create key frames for those,
but just set static values.
Under these conditions, if I click in any one of these
property fields, then I get a dialogue saying,
you're modifying the atmosphere at a non-zero time,
do you want to create key frames or not?
We don't want to create key frames.
Click no.
And that enables the forbid animation button up here.
Okay, now we can make our changes.
The direction will be 60 degrees,
velocity of 20 meters, and the rate of change
or churning of the clouds, 0.1.
And that's all there is to that.
We've set up the parameters for the uniform simple repeater.
Click okay.
And we'll render another preview,
this time we'll turn the uniform simple repeater
layer on, and turn the trees layer off.
And that way we'll only render the clouds.
Once again, we can delete what we have,
right-click on the preview options.
Discard current preview, and then render a new one.
After a few minutes that preview has rendered,
and as you can see, the clouds are moving
from left to right, according to the direction
of 60 degrees, and they're also changing shape
ever so slightly.
We can pause that, scrub through and examine one of these.
Remember that, if you hover your mouse over it
it will be highlighted,
so that's gonna change its color.
We can see that they are in fact changing shape
as well as moving.
All right, that shows us how to create cloud wind
and it also illustrates the importance
of the forbid atmosphere animation button
in the atmosphere editor.
