All language subtitles for 12. Exploring Beam Effects as an Alternate Look

hi welcome to our course

on creating high tech projectile weaponry in nuke

in this class

I wanna show you guys

how to create some alternate looks for our projectiles

I just want to show you guys some different ways

of creating different looks for these type of effects

so for this new look that we're gonna do

we're gonna create a look that is more of a

more of a bean coming out of the

the weapon as opposed to a

a shell or a pulse

or a singular shot

we're gonna create a look that's more of

like a bean type effect

so in order to create the look

what we're gonna do is

we're gonna basically replace

our distortion blast with the new element

so I've gone ahead and just

disable the nodes that create the distortion blast

and I just created some space in between that

and the rest of the script to

for us to create our new nodes

so one of the first things we're gonna do is

we're gonna create the beam itself

so for that

I'm gonna bring in a roto node

and I'm going to create my first frame of the node

right after the muzzle flash

so I'm gonna scrub through

and find out where the muzzle flash is

so it ends on frame 45

so that's where we're gonna create our beam

using our roto shape

so all we're gonna do is just create

a long rectangular line

like this

and we're gonna just feather it out

so something like this

we're gonna plus it over

just so we can see how it's looking

I want a bit of a stronger center

and a bit of a weaker fall off

so I'm gonna

reduce the size of the center of this a bit

something like that okay

next I'm going to track this to the tip of the gun

so I'm gonna bring in a tracker note

and we'll begin the track on the last frame of the

muzzle flash

so we can set the frame to frame 44

we'll do a match move

if there's any motion blur we'll turn that on

and we'll add our tracker point

and what I'm gonna use to track is

I'm gonna use this little divot here to track

so I'm gonna place my

tracker point here

actually what I'm going to do is I'm going to

track this I'm gonna hand track this

so I'm gonna have to track this off of the plate

so we'll just go up to the top of the script

and just track it off of the plate here

I like to add a grade node when I'm doing a hand track

I find that it works better

when you're not viewing the actual tracker node

you kind of need to view above it

to do your hand tracking

so that's kind of why we're doing it this way

so if I view my grade note

and I start scrubbing forward

I can manually move this

and it'll track as a hand track

so I'm gonna do this for about

you always wanna have

more tracking information than last

so I'm gonna track this for about

maybe 10 to 15 frames or so

so we started from 44

alright that ought to do

it's enough key frames for our tracker

so I can delete this grade and disable that

and bring this back down

so if we go to our first frame of our beam

frame 45 only attach our tracker and we place this over

there we go

we'll just move this over a little bit

alright so we'll throw a little blur on that

um something like this is probably good

we can always adjust this as we go

I'm also gonna add a little tint to our beam here

to our but I'm gonna add it to the roto paint node

so we can just do that within the color

um again I'm gonna go something within the blues

slash purples so

yeah we could do something like that that

that that works for me we'll leave it like that for now

so now if we scrub through

and we can see that our beam is tracked to the nozzle

which is what we want

perfect

next we're gonna add a grade node

to the main part of our script

main part of the tree

right under the

where the beam goes over the rest of the script

and with this grade note

we're gonna use this to gain up our beam

so it's really bright

quite bright as you can see we're gaining everything

so I'm gonna mask it off with this

there we go

so now when we gain it's just affecting the beam

so maybe something like that works pretty good

then I'm gonna wanna glow this

so I'm gonna throw a glow node under the grade

I'm also gonna mask that off as well

I like to add a filter road in a blurred

just before it goes into the glow

just so I can control the size and

density of this being here

I may not use them

but I like to have them there

just in case they do want them

coming into the glow

no this is where we kind of again

push and pull until something cool that we like happens

the brightness is brightening it up too much

so I'll leave that alone

I will increase the blur here

maybe I'll go back into our grade here and

reduce that a bit

as well as this glow here

something like that it's probably okay

again what I'm trying to do is I'm trying to get a nice

hot center with a nice fall off between

so something like this with a nice hot White Center

with a nice blue cool fall off

so that's what I'm trying to create here

I don't want it like that and I don't want it like that

so somewhere in the middle

it's pretty good

yeah something like that it's good

so I'm gonna just animate this on and off

just so that we have some

working points to work with

the first frame this is on is on frame 45

so that's where I'm going to use this

and what I'm gonna use to animate on is

I'm not gonna animate the over

I'm just gonna animate the actual road of paint

note itself

cause that's the base of everything

so if I go to the opacity and I set a keyframe

have one go back

turn that off

and then again

this is something we can adjust

I'm gonna allow this to stay on

for about 10 to 12 frames and then turn it off

I can adjust that to make it longer

shorter as we go throughout the shot so one

we'll see here

it's probably good for now so I'll set a key frame of 1

go forward and key frame of zero

there we go

so now if I play this if we view this

this is what we have

alright which is what we want

alright so we've created the

first part of our beam effect

uh next class

I'm gonna show you guys

how to create some particles to add to this

to kind of boost the look and feel of the uh effect

so join us next class

see you next time bye
