All language subtitles for 08. Adding Interactive Lighting to Our Scene

hi everyone

welcome back to our 7th class

in our course on creating high tech uh

weaponry and nuke

um last class

we focused on creating

um plate uh

distortion effects

and in this class

we will focus on creating interactive lighting

from the muzzle flash and projectile on our weapon

as well as our soldier

so in our earlier classes

we created um some mats

created a gun mat

and we also created

um a body mat

so we will be using both of those in this lesson

so I'm just gonna grab those right now

and bring those down

that's these right here

and so we'll start with our

the gun portion

so if we go to where our muzzle flashes are

so let's frame

43 44 that's where we'll create these

so what we're gonna wanna do is we've created

our gun mat here

we're gonna want to

also pull a key

on the plate

to get some of the highlight areas of the gun as well

so we did that for the body mat here

where we were able to get some of the highlights

not so many

but just a few

and we'll do the same for the gun

so if you grab a key or node

and we can just share off of this stream here

we're gonna key this until we get

some of the brighter areas

kind of limited into the key so kinda

something like that it's probably good

so I'll name these this is gonna be our body key

this is gonna be your gun key okay

now this plate distortion we did last class

is affecting the placement of a gun

so we might add this

before the distortion on the plate happens so here

so we're gonna grab a grade note

we're gonna attach it to our mat

put that into the stream

and we will also take our gun mat

and multiply that with

are gun key so if we multiply these two

we get the gun by itself

within the gun mat

so if we go to our grade node

in our plate here

and we start gaining up

you'll see that we're getting our gun here

so we're gonna do this two fold

we're going to use

the gun mat on its own

and we're also gonna use gun mat within the key so

we're gonna be color correcting two portions of the gun

so this first portion here will be our

entire gun that we're going to color correct

so we're gonna want to animate this again

with the muzzle flash

where the muzzle flash is smaller

will have a smaller value for our interactive lighting

where the muzzle flash is larger

will have more

so Frame 43 will say something like

maybe something like that and we'll set a keyframe

then the next frame will go even more again

these are it's daytime

it's a very powerful

we'll assume it's a very powerful futuristic gun

so we can again push these effects a bit more

so we'll do something like that

and we'll animate that

and then next frame

because there is still a projectile

will keep the lighting on

but a little bit less

we'll bring it down

then our next frame

we can turn that completely off

all right then for the second portion

we'll go back to our first frame

and we will gain this up as well

it's also the key frame

for where the muzzle

fascist larger

will go a bit more as well

with this set

our key frame

and then a little less

once the projectile exits the gun

and then completely off once again

once it's exited the screen

so there we go

we will also do the same thing for the soldier's body

so for his body mat we will grab a grade node

looks like we only did roto shapes for

the frames before the muzzle flash

so we'll do a few more

again this can be pretty rough doesn't need to be exact

it's a frame 43

see we're gaining them up here

so we'll maybe do something like this

for the first frame of the muzzle flash

next frame a bit more

next frame little less and the frame after back to one

so if we view what we've done

we should see some

lining effects happening on the gun end the body

now normally

what I would like to do

it I'd like to kind of go in and like

make the lighting effect a bit stronger and the nozzle

have it fade off

but um you know

these are all things you can do later on

I don't need to show you how to do that

just want to give it basic overview of

just kind of how the lighting effect works

um so we've done that and um

we're done for this class

and I will see you next class
