[Autogenerated] in this clip, we're going to be looking at the remove note.

Remove channels.

Node allows us to very quickly get rid of other channels

that we do not need for a particular task.

This image has a lot of image layers.

We have ale, multi diffuse body direct spec U V s.

I mean, we have lots and lots of different layers,

but we may not need those, so let's get rid of everything.

Let's select remove and its default will remove all channels so you

can see all channels are now empty for go back.

You can see that on Lee.

The default three are there now.

So what we're gonna do is we're going to remove not but

all but will remove just the oil multi.

So you can see now that is no longer there and will remove

body diffuse and you ve depth and multi Matt.

And you can see as I get rid of those different layers,

they're gone from the primary list.

They're still in the secondary list, but they're no longer here,

and you cannot select them or see them.

Now let's go back to default and switch our operation not from remove,

but to keep What are we going to keep?

We can keep all or weaken.

Just keep the UV depth.

So now everything is gone except UV depth,

which weaken select, but it's not in the RGB.

So if we want to, just keep the UV depth, but copy it to the RGB A.

We could use a shuffle or a copy note to move those channels around.

The removed node is a really great way to remove data

quickly from our image layers so we can composite with

better workflow and better efficiency.

To recap,

I want to talk about how channels are the foundation of all good compositing.

The shuffle node lets you rearrange your channels.

Shuffle copy adds another input.

The copy node moves and copies channel sets.

Add channels will create empty channel sets and remove channels.

Lets you easily delete large amounts of channels for optimization ins.

Don't be afraid of these powerful notes.

These nodes will help you define your greatest composites.
