NEW TUTORIAL: Dynamic Machine Gun

In this tutorial we will create a particle system for emitting specific particles based on a surface type. For example, when the emitter is on the ground we see dirt chunks and when it touches the water we see water splashes. This technique is easy to setup and can be used for motion graphics situations that require dynamic particles types that would be difficult to hand-animate.

The project files contains the expressions and some sample footage to start understanding the concept. For high-resolution footage elements, please check out Action Essentials 2 from our products page!

Side Note: If you use multiple elements from Action Essentials 2, you can create more random effects, like this.

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 […]

THANK YOU. i remember asking you to do a 'tut' on this last and my brother david, we used a garden hose with holes in it,, we wanted to make it look like a spitfire was chasing us and shooting up the ground.
so w, we hid the hosepipe and then quickly turned the water on and off.
it didnt work well.

and dad went nuts when he saw the hose pipe.. maybe this summer we can try again wtih this
thanks again

Well.I Love you, Andrew)))) Doom was the first videgame I played, but I rather expected to see BF3 or MWF 3 than the good old Doom))))))))))))))) This was funny point of the tutorial. Thank you for showing us unlimited possibilities of AE.In my opinion Adobe should pay you and help to support the site!!!)))))))))))))))) May IT BE so and until then were buying your great products!!!
Looking forward to buy VC Element 3D

Hi Andrew,

Another excellent Tut. I see.

Listen. Could I please get those expressions in a
text file instead of in the project file as you originaly
suggested ?

I don't have that version of AE, but I can still use
the expressions.

If you would be so kind it would be greatly appreciated.

i realy love that tute kind
5 years ago it took me a little while to get bullet holes to appear on the wall and then the ground. I am glad you left that out, you know to make us think. Also, I took the displacement trick in the Epic Shatter to make ripples in the water hits.

What a fantastic tutorial. This is the stuff that really puts this site ahead of everything. BTW, I like the Detroit joke, I don't think you missed on that one ;)

It's cool to see your progression as the years go by. O and thanks for reminding me how awesome Doom was.

Wow, this is a remarkably cool one! Never thought about
the split clip alternative in particular,cool expression setup and very interesting use of Trapcode P.with different layers and sprites. A lot to learn from and definitely even more to play around!Thank you very much! LK

Freakaliscious mate! I was actually able to follow this one (coming from a programming background). Never thought of adding "smarts" into After Effects. This opens up a whole to new can of possibilities! Tell me, is that brain of yours always in 'thinking' mode to come up with these ideas?

Thanks again for sharing despite your busy schedule, it's appreciated.
