We're gonna look at the shuffle.

Copy.

Node Shuffle Copy is just like the shuffle node.

Except it has to external inputs.

We can get the shuffle Copy from the drop down over here.

Now let's take a look at what our shuffle copies doing A shuffle copy

you can see now has are two inputs allowed into it.

Now, this input is not connected to anything.

Now let's take a look at our Alfa Channel Are Alfa Channel is empty,

Does not have anything available.

So what we're gonna do is we're going to bring in an

external image as an Alfa channel.

I'm gonna bring it right down here.

We're gonna hook it up to input number two.

So now we have a RGB pass, which is just over here in the RGB.

And then we have a Alfa Channel, which also exists in RGB,

but not as a alfa itself.

Now the Shuffle copy is gonna let us rearrange these

channels in the way that we want.

So let's take a look.

We have input.

Number one is gonna be our RGB.

So input number one.

We want to make sure it's r g and B right here like that.

Now, Alfa, let's turn that off.

We don't need it coming from input one.

What we want is input number two and we can select

just the RGB inputs and weaken.

Do that and we can say, you know what are red is gonna be our Alfa,

so we'll check that off.

So now what we have is input.

Number one is pulling in the red,

green blue of this image and it's pulling in the Alfa

of this image from the Red Channel.

So let's take a look at this.

There's our Alfa.

There's are rgb So I'm heading the a key to toggle back and forth.

I can also hit the M key to see the Alfa over laid on top of the RGB.

Let's go over to the shuffle copy and disable it.

It's on Lee giving me one of the channels.

Disable that again and now I can see hit the M.

That shows me a map overlay.

Let's go back to our shuffle copy interface Now,

we didn't have to do it this way.

We can keep these linked together or we can

actually invert these connections now.

Easy keyboard shortcut to invert Any connection on a node is

select a note and hit shift acts and that will flip whatever

connections are and reverse them.

I'm a shift x again.

So this time the alphas coming in on Input one and the RGB is coming in on

input to so we can see that our images kind of broken.

So let's redo this RGB So here's our a Red is coming in on input to want

the red We want that green who want that blue that we have a full color

image if I look at the Alfa Alfa looks all wrong.

In fact, the Alfa looks like one of the color channels.

We look at the shuffle Copy.

We can see that the Red Channel is currently being shuffled into the Alfa.

The Alfa Channel is being stored externally off of him.

Put one So we go to input one read,

Here's the red we come down and we see that is our connection.

So we select that and there we go.

Now we have our Alpha channel in the right place and were able to

rearrange and pack our channels accordingly.

So the main difference in the two nodes.

Shuffle and shuffle copy are in where the inputs come from.

Shuffle copy allows us to bring in external additional input.

One end to shuffle only has that one input,

but we can bring in additional inputs from the internal side within the shuffle.

Note.

In the next clip,

we're going to learn about creating new layers and channels

within side of the shuffle and shuffle copy nuts.
