All language subtitles for 05. Creating the Distortion Projectile

hi everyone

welcome back to our 4th class

in our course on creating high tech projectile weaponry

in nuke last class

we focus on creating muzzle flash

lighting effect for our gun

in this class

we're gonna focus on creating the actual projectile

that exits the nozzle of the gun

so let's get started

so for creating our

distortion effect that's gonna be leaving the gun

one of the first things I like to do is

actually create the mat for that

so we can go ahead and bring in a rhotal paint node

we will time it to exit the gun right after his first

gun blast

to somewhere there

so we'll view our Roto Paint node

bring it in ellips

leave that there

next we will grab a noise node

we'll view that

um we'll bring down the size a little bit

something like that

and then we also wanna animate this so that it's moving

so you can kind of go to

early on the frame range and set a key frame

uh the Z is the actual motion of the uh particles

so if you slide the z uh

parameters you'll see that the noise actually moves

so I'll set a key frame here

then I'll go to the end of my frame range

and set it somewhere there um

the further on you well

the higher the number

the faster it goes

so you can kind of just play with it and see what works

it's a little slow for our purposes

so I'll increase this

to maybe like a 6

now if we play that

let's look could be a little faster

so maybe we'll make this

that's probably okay so we'll stick with that

next we're gonna multiply the two together

I wrote a shape in our noise

and we'll get something like that

we'll throw on an edge blur

this is soften up the edges

yeah we'll say something like that

we can maybe make this a little smaller as well

alright so if we go and view our current comp

and go to the first

frame right after the muzzle flash right there

and we'll place our noise shape over

and we'll grab a transform node so we can move our

noise shape scale that down a little bit

now I'm going to make the

alpha of this a little bit stronger

so we see it a bit more

alright so we see that there

next thing we're gonna do is

we're gonna bring in an eye distort node

to be used for a distortion

and actually before we do that

I will actually just go ahead and animate this

kind of through

so we'll turn this off in our overnode for this frame

where we don't see it

and then for as soon as the muzzle flashes off

we will see the

distortion so we'll have that

we'll say exiting here

we'll set a keyframe for our translation on that

as well for that

so if we go for nothing we'll see our that

in the next frame it'll be off screen

so basically this is what we have

alright

now for this distortion to work

we're going to need to copy in

the alpha of this into our stream

and then use that as a map for the distortion

so grab a copynote

now if you view the alpha after the copy node

you'll see that

the distortion bubble is actually in there now

so if we go to our eye distort node

and the channels we want affected

will be our RGB channels

our UV channels

are the channels that we're gonna be bringing in

to create the distortion

that will be our RGBA

our alpha channel

and once you start

actually we do not need to see the

distortion bubble to actually visibly see it

so we can kind of kill that for now

we just want to see the distortion

we will also use a mat to hold in our distortion effect

so we'll add that to the chain here

and maybe we'll actually

do it this way

will use the unnoised effect

instead

forgot to add our transform mode

so there we go

so if you toggle between on and off

you can see that there is a distortion happening

right around where it's supposed to

so we can scale that up

maybe make it a bit stronger

now we can bring back the actual RGBA portion

you can

keep that

light

and if we play this now

we'll stop it

we'll set a key frame or key frame range to view this

so there we go

you can see that we now have somewhat of a distortion

effect exiting the gun as he blasts

we will refine that next lesson and

keep going from there

so thanks for joining us

and we'll see you in our next class thanks
