hello everyone and welcome to another After Effects tutorial my name is Tyler Bradway and
this is creative it's studios today i'm going to be showing you how to make blood in After
Effects so that you don't have to use like action essentials or things that you can't afford let's
make a new composition and hit OK make a new solid command Y hit enter and type in particle
world right particular add particle world so this is what we have it's just going to be this crappy
little explosion thing first we want to change the producer radius to 0 for all dimensions and then
for physics we want to change it to Direction axis and that gets us this lets move the origin
so like right here next make a keyframe for the first frame and then come over here and put it to
zero like one frame in that's gonna make it just a squirt you know and we got to change the particle
type because it won't work if it's a line so we'll change it to faded sphere and that reduced the
amount of particles for whatever reason it just does that so we'll just increase this to like
10 or 15 so we're gonna make multiple instances of this particle world so we're gonna we'll try
to keep the birthrate pretty low the number of particles pretty low for velocity we want to
and resistance we can have it at like point two so that's just gonna slow it down as it as it catches
the air sort of for extra that's the important one we want 0.9 or one I'm actually gonna do one
and that's gonna spread them out horizontally if you go over one it it spreads it too far so we'll
just do one change the size variation to 100 and we don't really need to change anything else other
than the color obviously so we're gonna change that to dark red and let's take a look so let's
duplicate this layer and go back to the bottom layer because it already has all the parameters
open change the velocity to like nope we're gonna change the extra sorry we're going to change the
resistance to like 0.7 ish and that's just gonna slow down those particles some and as you can
see they're just duplicates of the first ones so we're gonna actually want to add a random C
so that they're not the same particles reduce the size if we have smaller particles they're going to
catch the air easier and have more drag so that's why we increase the resistance and we also want to
increase the velocity just a little bit because they're smaller particles they're gonna come out
faster we'll increase the volume of these smaller particles so we'll do like 17 so duplicate this
top one and we're gonna reduce the birth rate to 5 decrease the velocity to like 1.5 gravity
resistance can be 0 for particle size we want point three and point three take a look so that
one was these particles so now we have a bunch of like particles going at various speeds and they're
kind of spreading out when they come down that's what we want so let's make it look like the one
command alt Y to make a new adjustment layer and add a vector blur to it change the amount to 150
and that greatly reduces the amount of blood there is we're gonna add a simple choker to that and
enter minus one for the back - - just to add more thickness to the blood that's too much actually -
one something great about particle world is that you can actually turn on motion blur for it so
that's gonna help our particles a little bit more know why it's making new adjustment layer and add
pixel motion blur this is gonna make motion blur out of the difference in the pixels between the
frames so let's just take a look so that's it for this tutorial guys I hope you learned something
this is a valuable technique I think if you want to see more subscribe like this video if you liked
it and share it - because that's helpful thanks for watching guys I'll see you guys next time
