All language subtitles for 06. Preparing rough layout via 3D projections

in this lesson

we will continue roughing in our mushroom cloud

via our 3D projections

so where we left off

as we had just selected the point cloud data

to be able to give ourselves a rough idea

where we might want to place our overall card

in 3D space

so now we're gonna take that card

and drag it forward in space

and just kinda zoom in just a little bit there

and you can kinda see that we're dealing with the fact

that all the point cloud data

is kinda clustered right there

now that's the mid ground data

a lot of that is

some of it is building information

from the background of our plate

some of it is midground

as well as there might be a little bit of foreground

but I'm willing to bet there's not

because that railing kind of disappears

quite the majority of the time

in the actual background plate

so right now

I'm just going to

put that mushroom cloud somewhere right about there

it's not it's not in a perfect spot yet but we can

we can just assume that it might be there

now I'm going to jump back into 2D view

and now you can see where that mushroom cloud

currently is residing

based upon running it through the scan line render

so what I wanna do is

if we turn off that transform node

you can see it's just scaling it up and moving down

we had moved it around just a little bit

that's fine

what we're going to do is

we're just going to adjust

and get it lined up for where we want it to be

so let's just uh

full screen

and I'm gonna actually take that center point

of the control

and I'm gonna move it down here

just so it's easier to work with

so what you can do is

you hold down control

and left click on that

and just move it over

and that you'll actually see where the center XY

the coordinates will adjust when you do that

if I do this

you actually see

right there

just adjust

and it's compensating the

translate XY as well

so now that just makes it a little easier

so let's move him

what we're gonna do is

we wanna put him downtown somewhere

right about there

I'm thinking

uh so let's zoom out a little bit

give ourselves a little more viewing

we wanna we

we might wanna move it up a little bit

give ourselves

you know let it

let it use the frame just a little bit more

that's possible

uh we it's really up to

taste how you

how you feel that blowing up this uh

the cityscape might look

it's really up to you

now we're on frame 4:20 eight

so let's do this

just for kicks

let's jump to frame 600

or somewhere around there

let's see if it lines up

check that out

see it's now tracking with our camera movement

and that's exactly what we were intending for

to do via this image projection

so always remember that

at this point

frame frame

frame 4 28 is sort of our master frame

and at this point

we've just roughed in

nuclear explosion

uh for downtown

now the whole point of this

though is we want it to go behind those buildings

so for to go behind those buildings

we're going to need to

in the next lesson

actually work on

creating some holdout mats of those buildings

but in the interim

for the moment

what I want to do

for our our final

just quick step in this lesson is uh

just do a little bit of comp cleanup

we kind of have a bit of a messy comp at the moment

just because

some things

we're not using

some things

we don't need

uh our grid warp

we are going to need

so we'll use that shortly

uh and where the grid warp's gonna happen

will be prior to the 3D projection

so it's actually gonna go somewhere probably

I would be willing to bet

between the transform

of the time offset

but for the moment

what we wanna do

is just clean up

some things we don't need

these nodes

we've already used

over there we aren't

we aren't gonna use them again

so let's just delete those nodes

this point cloud data

maybe we might need it again

but let's leave it

leave it off the side

without deleting it

the lens distortion

we are going to use

because we want to run

our nuclear

mushroom cloud through that

so I'm gonna take that off

I'm actually move it over here

for the moment

it's actually gonna go

after the scanning render

and finally

our camera is just gonna go right down there

we lined everything up

and make just

makes it look a little more tidy now

at this point

I think what we're going to do

uh reorganize

while we're

reorganizing

I think we're gonna shuffle things

a lot of times

at least for my personal taste

I like top down

compositing

uh which means

you're gonna work from top down

so anything on the B input is

it's a over B

so B is your primary

so that's basically

from the back of the plate

to the front of the plate

so the back

and kind of think of

top is your back

and bottom is your front

so that's why I'm shuffling these nodes over

just to kind of

line things up

and then what we'll do

is just move these cameras

off to the side here

and this information

can just go over here

we can get rid of that shuffle

and we really don't need

any of that information

we don't need the plate anymore

but I'll just leave it

for the moment

because it's good to

it might it might be

useful later

on or you might want to use it

at this point

to mess around

with your camera

track a little more

maybe you wanna try to

clean it up

a little bit more

or not anyway

so at this point

we have roughed in

our nuclear mushroom cloud

I think at this point

what we're gonna do is

we're gonna

take a quick break

and then we'll come back

and we'll begin on the

working on the holdout

for the buildings

and then we'll start

refining that

mushroom cloud

and further

integration

to better seat it

into our actual plate

but to do a quick recap

in this lesson

what we did was

we finished up

working on our

3D projection

in using frame 4:28

as our master frame

and just lining up

that nuclear

mushroom cloud

with downtown

so that then

it would match

with the movement

of our camera

uh tracking data

that we have uh

run through

a few lessons ago
