All language subtitles for 04. Implementing the Muzzle Flash

hi everybody

welcome back to our 3rd class in our course

on creating high tech projectile weaponry and Nuke X

in this class

we're gonna focus on the fun stuff

we're gonna begin the real meat of the work

by creating some of the effects and the projectiles

that happen at the nozzle of the gun

so let's begin

so in last class

we focus on creating mats for both the gun and the guy

firing the weapon

so now we're gonna begin

some of the actual gun blast effects for the shot so

one of the first things I like to do with this

is begin with some of the actual lighting effects

so one of the things that we're gonna wanna do

is find where he first begins to fire

and then we're gonna want to do some animation

around that area

so the first actual

shot seems to take place somewhere around

you can just kind of see the recoil in the gun

and use that as a reference

so somewhere there

looks like he fires

yeah somewhere looks like

looks like frame 45 is where the recoil happens

so we're gonna want to use a couple frames before that

and a few frames after that

so let's say 45 is the frame where he fires

we'll go two frames before so 43

so we're going to want to start with is a roto shape

I like to start with an ellipse

and kind of

use it

somewhere in the nozzle there

this is gonna be our kind of our our

our light flash at the very beginning at the uh

of the gunblast

so we have that

I like to throw on an edge blur

something pretty high

like to throw out a gain

gain that up

add a little color to it

I like to work with blues light

blues tend to look pretty when doing this kind of stuff

and then a glow node

so now you can take that

and place it over our plate and see what we get

so we get something like this alright

so the way this is gonna work is that the very

we're gonna use two frames using this uh

this circular light blast effect

so the first frame

say frame 43

is gonna be a bit smaller

that on frame 44

it's gonna be a bit larger

and it's gonna disappear on the recoil

being light

the physics behind it is that it wouldn't

you wouldn't see it that long on frame

so you don't wanna hold these things for too long

so one or two frames maximum

is all you need for a lot of the lighting effects

so for this I'm going to make it a bit smaller

I'm going to

actually after the edge blur I'm gonna throw in a blur

regular blur node just to blur it out more

or say something like that

and then with our glow node

uh we can leave our brightness and saturation all alone

will just increase the size of the uh the blur

so do that and then we'll also tint it

give it some additional blue lighting or coloring

say something like that

and we can use the brightness node in the glow

to kind of play with our sizing

as we kind of animate between the

smaller frame and the larger frame

so frame 43 will place a keyframe on our brightness

in our key glow node

and I will say something like maybe that

even maybe make it a bit smaller

okay and then

on our next frame we will increase the size

okay something like that maybe

and then we can turn it off on the actual recoil frame

so in our actual merge node

we can set a keyframe off on 45

on on 44 and 43 and then

off again on 42

so this is what we look like we have

if you scrub through frame 40 41 nothing

frame 42 and 43

we have our lighting effect that kind of grows in size

and it's off on frame 45

so if we play this

we'll just I'll just set if frame range

that's not the full range

we don't need to see the whole thing um

alright so that's the beginning of the

muzzle flash gunblast effect

um we're going to be using the mats that we made before

as our interactive lighting for

for this area here

so in this class

we covered uh

creating some of the beginning lighting effects

for the muzzle blast

um next course we will

uh or destroy

next class we will push this further

and create some of the actual projectiles

ejecting from the gun

as well as some other lighting effects

uh thank you for joining us

and we'll see you next class thank you
