And come back

Understand a little bit about needs 3D system

In some of our masks

Left at the end of video five

We have our shop here and

We have this colour cracked adjusting or Scylla and the make sure that this is being tracked

In the whole time

So first let's go ahead and bring in a camera

In her element we have the shot

This was rendered that in here

And when we look

We can see here is our camera is automated it's moving to find some information about

We can see that

In The Shard

So we have that

Keira

We need to do is lie down

Just dropped that in there

Look at this is obviously very time

And we want us to be our ground plane so let's go ahead and send it to his ex

And then we're going to uncheck image aspect so it's a big or Square

So we can go ahead and scale this

Something

1700

Something like that

Search go ahead and check this out what a grid on here

Just typed that texture in

Prince empty currently that's because I'm looking at a rgba sky what switch it back

What score in just make this

Square format in cell change

Reformat no 2K

And went into this reformat is going to adapt

Format size and it will now be perfectly Square

Just like your card

Ring just make the size of a grid

Increase the number as well

Also we have our card here

Looking good what snake scanline render

Type it in here offer or Cameron we can called the

The RBS shopkin

Virgin just using him

Now we can see

It's moving based on our team

Making a couple of Samsung's in here that are potentially dangerous

Mainly assuming that are 3D seen as a ground plane

That is perfectly at 0

That is not the case should be from necg scenes but occasionally the grand final be on time

And if this is more often it's not going to track correctly

So how can we tell where

There should be in Tralee space

What is a pretty cool pass included in our render queue

Is the position pass

And it's represented by P

Position pass

If you look at are RGB values here or seen or the actual 3D coordinates

What are pixels

Any given point this is exactly where is in 3D space

Lose a few different ways to use this in you

How can I use it right now

Is with a node called

Position to points

It will make this right here let's go ahead and look back in rgba

I'm just going to play bit in the right here and look at it

It's not displaying anything

That's because we need to give it a surface point

Or position pass

And now you'll see

It's made a point cloud

H

3D space and this is really cool because what will be able to do as we can use this as a guide

Play surgery on a tree so I can have a tracker actually get in point in a scene

So what you want to do is make sure that our grid is aligned with our for

Sophie G or a widget here then we can skip this up a little bit actually

Make sure that is covering the whole ground playing

If we can get it over attach

Something roughly like that should be good you look further

Covering the brown spots to start sliding up and down and see when it starts to disappear

So we can see it starting at intersect with her points right around

Negative

You can take it down without further

Can see this is actually where our grand fine is this would have been sliding a little bit

Ahead and Chaka orthographics you feel look at the right side and

We can see that some of the points are up here there's also another level of the ground at all lower

What happen if we went right here

Go back into the normal video

Looks like we have some points you about our little bit of love

I want to make sure what was sticking to is this main ground playing so we can just go ahead and scoop that

Probably where it was

Like that

Is pretty good

Britain in wine for ground plane so if we were to merge

This over

Alexa what's going to make these lines that so

Just

Turn the size down a bit earlier Cassidy

Let's go and play this and make sure that is sticking

As we can see here it looks like it's really well

But as always we want to check this with a stabilised to make sure

It is not shifting around because it's always difficult to tell

In Motion

What's the best way to do that because we could just make a 2D point track on her shop here

And track it that way

You should never have to do any manual tracks we should be able to get the data

From your camera

And the point in 3D space

Check this

Make a note to reconcile

3D

And this note has a few different inputs

It has a camera info

Image input

And then an access input

And what does snowball do

Is it going to take a point in 3D space

Can I look at image and then it's going to look at our team

It's going to tell us where

In X and in y that point is

So it's going to result in a skin attract too deep

That we can use to stabilise

Let's go ahead and see how this works

What position 2.0 again

Cash Generator Harpurhey

Snake and access really quickly

This is just a normal in 3D space

And screwed it over here

And we want to place this where are stabiliser point b

Determined with a card

This is -12

And why is it always go ahead and type that

Negative 12

What's my head and pipe in our access

Now we can do

Is he

Create keyframes

And it's going to calculate that position is

For the entirety of our shot

And then now it is moving around it actually acting like a transformer

Matchmove

This is actually currently tracking or image

What age is Chad

Stabilise

It's off centre quite a bit

But it has stabilised are shy

Go ahead and Stuart over so we can see it here

With that back

Something like this

And let's go ahead and play and you can see this has tracked our shot and stabilise it for us

It's a very kind I love using the snow when it comes from 3D

So hyper over laces actually allows it to preview a little bit quicker

This instance

And this looks very sticky it's zooming in so it's a little bit harder to tell but I think this is

I'm not seen any sliding camera and the right

Current position

So now

That we know that is accurate we can keep this or delete it I'm not playing on using it against me now this is

Sticking

Someone's going to get rid of that

And what you can do

Is we can roughly drop or mac

On

This card here

So when is I'm gonna turn the grid off

Make a mask

This output rgba

And now let's quickly create another

You can't see her

And what I want to do

Is reiki I just want to draw

Rush hour

Probably something like this

And you'll notice that

This is inverted and flat

Go ahead and rotate this 180° in Z

And now this is on the right side and we can now just roughly

Can you something like

Make sure that we're coming at 4

Range Rover here

And then we can just copy and paste this that we had a soft mass

And so now this is nice and stick

And we can just type this into my Sky now

Let's work at rgbi Sky

Go to the frame we aligned the song 202

And when we swap these

Is pretty much no difference or mask is all tighter it looks like so we could probably scooter out

Attach

And yeah now you have a skin and we didn't really have to do any tracking workers on a medically

Sticking for us

My head

Just make a backdrop here

I like making my backdrops for 3D

2610 0 and 0 everywhere else

Chichester Ford and we can just labelled

Mask

You may be thinking to yourself that it is unfortunate that we had to read

This is rubbish

Be nice if we could have just reused the one that we had exactly how we would do that we start looking at

Fractions in a couple videos

To do this to show a basic way to get rid of a stick just using a card it's a little more straight

Then a projection setup

When you're first starting out

So we'll definitely work our way up to them later this

Another we have a mask tracked in let's go ahead and start using this exact same 3D setup

Working on our digital matte painting for the

Thank you very much for listening and catch you in the next one
