All language subtitles for Nuke Compositing for 3D Artists week 2 - Classroom - CG Master Academy_9

for week two's homework assignment

you will have two options

option 1 will be using this landscape footage

and the plan is for you to

use this footage

and based on what we Learned with the camera tracker

to solve for a camera

which we did um in the earlier video

so I want you to use the camera tracker node

and solve for a camera

and using that camera

I would like for you to use the um

use one of the point clouds to generate a verticy

to generate an axis node

and uh using that access note

I would like for you to use that to

along with the reconcile 3 d note

to output a x

y z coordinate

I'm sorry x

y coordinate

and from there

I would like you to use the data

the 2D position datas from that to either

apply volume raise to your footage

so have it have something that looks like this

using volume rays or

use the Reconsaw 3D data to um

apply a lens flare to the plate here

so the option is yours

I will provide the link for the Flair Factory gizmo

that's available on Wikipedia for you to do a um

variety of flares in there

or you're welcome to use nukes regular flare node

um to apply the lens flare to it

and the um the other option

like I mentioned would be the volume raise

and um apply volume raise to the footage here

um it's really up to you which one you wanna do

you're welcome to do both um

volume raise and flair on the comp

um feel free to also play with grading as well

so in this case

what I've done is

taken our raw render

done a little bit of um

color correction on there as well

so feel free to apply any kind of grading

so the scene looks different than what we started from

so here we've gone a little bit cooler

cast to this footage

so the option is yours

um and again

with the flare as well too

I've taken the flare

I've done a little bit of color correction to it and

plus that on the um

footage as well

so main uh main idea

for this assignment is to use what we learn to do

a camera tracker

and we would like to

for you to solve for a 3D camera

and then output and access

from the point cloud in the camera tracker

and use the access to solve

a reconcile 3D node

so that we could have x

y coordinates

and it really doesn't matter what

area you select based on your point cloud

in this case

I pick something that

gives us a good

good sense of like volume shadow

so you have this silhouetting happening here and

volume rays poking through

and same with the uh

flare note as well

so the position doesn't really matter

you're welcome

to put your flare or volume rays on the left

on the distant mountains

um somewhere in the middle of frame

feel free to experiment with that

but that is option 1 for your homework assignment

option 2 for this week's homework

assignment is using the um

3D renders of the Zilla and

3D City renders

and based on what we

looked at with the vector blur note

I would like for you to

set up the vector blur node using the velocity renders

for our renders here and apply

proper vector blur to your

to your renders here

based on what we did in this

in the lectures

I'd like for you to

make sure you're properly passing through

velocity data in um

your merge operation where your city

and Zilla renders meet

and um I want you to make sure that

you do any proper

clamping to the velocity pass along with making sure

you have the um

proper settings selected in your vector blur

like Normalizing Soft Lines

and Motion Blur amount

and then selecting

the proper velocity pass in your vector Blur node

and filtering out the channels just so you affect the

RGBA and from there

I would like for you to apply vector blur and um

go through and check

to make sure that it's behaving correctly

and correct for any issues that you see so that

throughout the frame range you can um

you're getting proper motion blur without any issues

um so feel free to um

look at the vector blur video again

for refresher on the

on the setup for the vector blur and this scene but um

that would be option 2 for your homework assignment

um it's it's up to you

you're welcome to do both

both options of the camera tracker

uh and also the vector blur if you like to um

tackle both

both aspects of this week's assignments

thank you so much
