welcome to this overview of PXF Merge Wrap

so here I have

an image an RGBA image that's from a key and I have a

background random background here

and I'm combining the two with an over

I would like to have a little bit of cross talk

between the two layers

I want the bright areas from the background

to spill on my character

have a bit of light pollution and vice versa

because I have

some very bright and saturated colors here

I want to bloom a little bit of her color

on the background

as if the light is bouncing on her and lighting the

you know moisture in the air or the pollution

or the dust in the air

just a little bit of pollution on the background

so you can kind of do that by

double comping and using the new Collide Wrap node

but I found this always to be clunky

so I've created a tool called PXF Merch Wrap

so let's have a look

we've got PXF Merge Rap here

and Merge Rap is meant to replace

your final over when you combine your best key

with your best background here

so if we combine our layers with Merge Rap

by default we have a pretty heavy merge wrap

let's disable both

so I've got disabled switches here

if both wraps are disabled

I end up essentially with an over

so there's no difference between merge wrap and over

if we disable both wraps

if I enable the back wrap

then you can see that her color

bleeds onto the background

so we've got two

adjustments here

how big do we want it so that's the backs blur

so the more we blur the farther we go out

and vice versa

and the back mix which is the opacity of the

backwrap

so if I lower the mix I can make this more subtle

so to see the effect I can

toggle it on and off

and you can see the skin tone and her

the red from her shirt is

bleeding a little bit on the background

I can choose to blend the

back wrap either as an over

or as a plus

so plus will behave more like a light wrap

so if you set it to plus

then the bright areas will spill on the background

but the dark areas won't affect your background

if you set it to over

then the bright areas will affect your background

but also your dark areas will affect your background

so in this case I want to simulate light bounce

so I'm going to use a

you also have the front wrap

which is a more typical edge wrap

so if you enable that

then you have the colors from the background

bleeding onto her

you can choose how far in you want to go

so you can go really far if you want to

create more of a halation effect or a bit

less further in by using the front blur

and you can use the front mix

to adjust how intense you want the effect to be

you can choose whether you want to over so again over

if you have some dark areas on the background

the dark areas will darken your foreground

if you set it plus then it's more

like a light bounce type of effect

where the dark areas will not affect your character

only the bright stuff will affect your character

and then you can adjust the size and the opacity

like so so this is a pretty heavy wrap I'm

going pretty ham for the demo here

you want this to be subtle

usually if you can tell right away there's a wrap

it means it's too strong

new for this version of Merge Wrap very exciting

we have a new secondary

tab here where we could add an extra

front merge and an extra

back merge so if you want to have a big one

to just

have a bit of a light bounce and then a smaller one

for example an extra

back wrap here we can enable it

make it small

like so and less intense here

so we could use the smaller one just to have a really

tight bounce really close to the edge

and then you can have your

front one or your primary one

and to have a big

big ol light bounce here so we can have two layers of

back wrap and front wrap

so if I enable a front wrap

I could have a very tiny front wrap here

like so and just

step on the edge here to blend the edge with my

background so now we have two

back wraps and two front wraps in the same node

and also a big upgrade now we have a mask input

and the mask input can behave in two different ways

so let's create some alpha with the roto whoops

with a roto here

like so so now we can

choose whether or not the mask will only limit the

effect of the wrap

so now I only have wrap inside my alpha here tell

so I can

choose to limit the effect of the wraps with the mask

or I can behave like your merge node

and limit the effect of my entire merge operation

so this would be the same

as using the mask input on your over

so most likely you want to limit the effect of the wrap

only so that's the default setting

so there you go

that was an overview of PXF Merge Wrap

I hope you've enjoyed it and I'll see you in the next

video goodbye
