- [Voiceover] Let's have some fun adding wind
to the plants and clouds.
First, for the plants, select them in the World Browser.
Maximize the top view, and get in closer.
You will see a blue triangle.
And that's the wind manipulator or gizmo.
As you hover your mouse over that, the cursor will change.
And you want to see a cross for your cursor.
And at the same time you'll see
at the lower left corner of the interface, down here,
Intensity and Direction.
Click and hold on that blue triangle,
and drag to set the intensity and direction.
This tool is imprecise,
and you'll not be able to get those values exactly,
but intensity of about 15 and direction of about 60.
Release the mouse and check the results in the camera view.
We can see that those trees are bent over in the wind.
If we play the animation,
we'll see the camera dolly forward as usual.
But when the camera settles down,
we don't see any motion on those plants.
We need to do an animation preview to see that motion.
To speed that process, I'm going to disable renderability
for some of the objects in the scene.
Click on the icon to the left of each object.
I'll disable renderability for the island,
the procedural terrain, the sea, and the clouds.
I'm only going to be rendering the trees in the preview.
Right-click on the preview options.
And let's do a final quality,
5 frames per second,
and increase the size of the preview to 4x size,
and click OK.
We don't want to unnecessarily render
the entire timeline here.
Because I want to test the movement of the trees,
I should render out a section
in which the camera is not moving.
To do that, I can change the animation start time.
Simply click and drag on this bar.
We've got a ground line there.
And click on that bar and drag it over
until you get to five seconds and zero frames.
And now this is the only time
that will render in the preview.
Left-click on the Camera Roll to generate the preview.
When the render has completed now, it plays automatically.
And we can see that, indeed,
the trees are blowing in the wind.
Awesome, so when I click anywhere,
we can now scrub through the timeline
and see that at different speeds.
Cool, so that's our wind for plants.
And in the following movie, we'll add wind to clouds.
