NEW TUTORIAL: Speed Particles

In this new 20 minute tutorial we will create a dynamic particle system that emits based on the speed of a layer. In other words when the layer moves fast enough, the particles go flying! Creating automated animation has never been easier!

I knew I would have 2 tutorials done in the same week! Mintues to spare.

I'm Sorry Shape Layers! I love you!
I must confess… I was never a big fan of shape layers…  we just didn’t get along.  I was used to using masks but suddenly (around AE CS3) the same mask tool began creating Red vector shapes. At first, they seemed cool enough but after accidentally adding shape layers to my comps, instead of masks, I lashed […]
Visualization Experiment and new Renders
Just playing around with a new After Effects experiment without using any 3rd Party plug-ins! I need to refine some parts of the effect but I really want to make a tutorial for it ASAP! Here are some other projects you may have missed! Using Element 3D bump mapping to create some Gold coins and […]
New Tutorial: Realistic Rain Drop FX!
In this tutorial we’ll use After Effects to create a realistic water effect without any 3rd party plug-ins! Great for adding atmosphere to a rainy scene or title. This effect is fully customization and can be used to create many cool FX! In this tutorial: Create a dripping water displacement map Simulate realistic camera DOF […]
Destruction Experiment!
What is this thing! I’ve basically combined a bunch of stuff into one experiment! I might have been inspired by the amazing planet explosions from The Force Awakens but wanted to see if I could get a cool version inside Element 3D. Few Notes on this experiment; I added smoke elements, shockwaves using CC Sphere, and even […]

Looks beautiful.

@Diegatxo, I think that texture is in Riot Gear.

This stuff is great. Thanks Andrew!

One question. Is there a way to get a similar effect to 'starglow' with AEs native tools? Thanks.

This is such an awesome tutorial. I will name my first born VideoCopilot in your honor Andrew and call my wife dot pest, I mean, dot net again in your honor.

Cheers for all the hard work

Thanks for this great effect, I'm putting together my first motion reel and this works great for titling. I also just purchased the evolution pack and have been experimenting non-stop with everything in it. Thanks again!

Excellent use of expressions! It made me think of an great movie idea. We could plant this bomb on a bus and when the bus goes faster than 50mph, the expression could make the bomb go off. Maybe Sam and Sandra Bullock could co-star? Anyway, great job as usual!

Hey thats wonderful tutorial I am really thankful to you for such great tutorials but I kindly request you if you could come up with wire removal tutorial in after effects it would be really graet.

Thank You.

hello I am having a problem with the render my particles do not apears at the final render! why??? please help! (I am not following the tutorial is just some inspirational results from the tutorial!)
9 years ago
Andrew! Very cool idea and realization is also cool. Very beautifully!
9 years ago
Your tutorials rock. Great work!

By the way, those '{ }' are also called curly braces.

I like this idea. One question (and I haven't tried it yet) is that I'm suprised Andrew never showed an example of using TWITCH to generate movement rather than using wiggle. Can you not get the speed from having added twitch?

I think it would be a great 'shake the drips off' kind of effect...
9 years ago
I'm starting getting expressions and they are so cool!

Thank you for all your great lessons.

Dustin, 29 seemed to work from earlier. Particles rendering was fast and it didn't seem too sparse. You're pretty much right about the other stuff too...

awesome tutorial. Ahead of the curve as usual. Keep it up

@ Dan

Andrew plays around in AE with ideas and things that he does in his time and occasionally shows us what he 'might' make a tutorial out of when he gets time.. what happens is that meanwhile he keeps playing with new things.. and decides to make other tutorials.. (that is what I think happens and I've been here a little while.)

@ Andrew

THANK YOU! I am really enjoying these expression tutorials because they are extremely useful for numerous things! I think you've mentioned a book or two about expressions but I don't remember on which blog/tutorial. Could you maybe let me know about your personal favorite?

QUESTION: Why do/did you choose random numbers like 29 in the 29*S part of the expression? Is that a number you found worked for you, or do you just like random numbers?

Congratulations for the 70th tut Andrew , this one is very nice ! Keep up the good work !

Hey Andrew,
I would love to see more tutorials with Particular you know there are some incredible results to be had. I am exploring Trapcode "Form" at the moment and playing with the audio map's very very cool.
I'm loving this use of expressions for this example btw.

Trapcode Particular is a stand-alone product from
I doesn't ship with After Effects CS3.

Great tutorial!
9 years ago
btw where did you get that texture, i can't find it in the riot gear collection or in evolution
9 years ago
Andrew, excellent stuff. Just out of curiosity. How do you know someone would fall off a car at 80 MPH??? Have you been experimenting with Sam again? Or was he trying to hang out with you and you were trying to get away and that was the speed you reached when he fell off the hood?
9 years ago
I think that i'll use twitch to create something very very cool with this technique
thanks andrew

try experimenting with twitch to see if you come up with something cool.
9 years ago
Warti, you can use the layer as the emitter but the key is to only emit particles at certain speed...

Very cool effect, Thanks!

Speed expression!
Andrew I thought you might do something like this, although I did not think it would be this cool!

Thanks man, you can have my last beer.

Hey Andrew

Amazing, these two tutorials.
I have one question, how can I use particle world instead of Trapcode Particular. Because I dont have that plug in.

Nice one!

Its all about expressions today...

Another great tut! I especially like how you sync your sound effects to the animation, it adds a lot of punch, I keep trying but never get it as good.

Thanks again,

You come up with the greatest tutorials. You make what seems so impossible like coding a cinch. You also make it possible to understand and use in other projects. Thanks again cant wait for the next one. I check this website everyday and have bought most of your products

First many THX for this new tutorial!

But is there a big difference when i use the Text Layer for the emitter Type ?

Hi Andrew
great tutorial as always but I was just wondering about the background texture you used did you photograph it yourself,
or did you get it from somewhere?

Excellent Andrew...great tutorial....

hmmm, im using AF CS3
but i dont got Effect>Trapcode>Particular
i dont got the "Trapcode"

what to do?
9 years ago
I must say i was a little disapointed that it wasn't about 3D text; until i watched it and realized how awesome expressions really are (and how they seperate the pros from the users).

Thanks a lot Andrew, i'll never judge a tut you drop ever again (no pun intended).

I thought you would make such a tut!!

just 1 thing... u had particular registered as an unlicened demo and u didnt get the watermark? any response?

Hello Mr. Kramer, thanx for all these valuable tutorials. Can you plz tell me from where you took training for VFX & 3D. I also wanna buy your DVD's, they are very valuable. plz reply
9 years ago
Hi there Andrew, all your stuff is tremendously helpful. I have a doubt, i see that in this tutorial when you wrote your text, the anchor point was set automatically in the middle. In my case the anchor point is always on the bottom left of the text.

May you please tell me how I can fix that so my anchor point can always come up in the centre of text.

All the best,

Love this effect. Thanks for the tutorial.

It would be awesome to see more examples of using expressions to drive complex animation, particularly stuff that's tedious to do by hand (e.g. imitating real physics - weight, momentum, collision etc.).
9 years ago
Thanks for your effort.

its looks sweet... i never realised this effect would be so simple...i mean i thought you need some sophisticated 3d program to achive this...
i guess the saying is right ..
