All language subtitles for 12. Setting focal distance in pgBokeh

in this lesson

we will learn how to set the focal point

in Peragon Labs Bouquet Plugin

so one one thing that I have discussed is

how to control focus

focus is done with the camera node

so if we look at focal distance it says 185

but let's set it to maybe 100

so we can see Grolo now which should be our focal point

he's now completely out of focus

in fact everything's out of focus

and something to point out is the bouquet shape

that is what you would use for the kernel input

the circle here we can actually change this

go to optical artifacts

excuse me go to kernel

instead of circular

so here's where we would select input

instead of circular we're gonna check aperture blades

currently blade count is six

so now we can see there's six blades

let's just change this to maybe three

get a much more dramatic effect

here we go it becomes much more triangular

set this back to 6

which is the most common type of amateur blade shape

okay let's try to do something else

maybe set this to 200

maybe set it to 500

okay so we can see now

the foreground is completely out of focus

but the backgrounds in focus

so let's say that the default value of the camera

from Maya was not already set to the

focal distance that we wanted

but would be an easy way to figure this out well

lucky for us

we can do that in Nuke's 3D system

so let's make quick

deep to points to plug in the deep

plug in the camera

and then jump over to 3D

alright so this is where things are in 3D space

can see this is where our scene is this is our camera

so if we look here

we can see the camera

right back here

there's this little X

this little cross

this is actually representing the focal point

this is at a distance from the camera's origin

from its filmback

that is the number of units we're looking for

so obviously we'd want to set it to something

a little bit more reasonable

something around the character

so just zoom in a little bit here

and then I'll show you as I move this

bring this down to 400 300 now it's appeared in frame

be a little bit more granular about this

now you can see it's moving

moving let's just set it back to 1:00 85 which is

I knew it would needed to be anyway

so it's right

right here in front of Gorilla's face

this is the focal point

so if you didn't know

where the focal point was supposed to be

this would be a really great way to do it

and if you needed to animate the focal point

for some kind of a rack focus

you'd be able to follow along in 3D space perfectly

just by using this

as a reference point

so there we have it

so this is how you use the basic functions of pgbok

you can obviously get into the details

of some of these things

but in general

these are the most important ones to creating a look

I'll go over them again

real world lens

real world lens simulation

make sure that's checked

and then make sure that the aperture

width and height match what the plate

or what the CG cameras aperture size should be

in this case

aperture just means filmback size they've

changed the name

depth style real and of course depth channel

deep dot front

always use deep if you have it

and the kernel to dial in some realism

so that's it

that's PG Bouquet

and I hope you've Learned something

we have now reached the end of the lesson

we Learned how to set the focal point in PG Bouquet

using point clouds and a camera in Nuke's 3D system

in the next lesson

we will put the finishing touches on our composite
