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.

You also promised tuts about how you did the motion graphics with the AE2 in the product.. And please tell me that you didn't finish posting the demon cam tuts. And is there an estimated time for when you'll publish Element 3D?

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.

Nic.

Andrew, could have sworn I saw a commercial for some upcoming TV special that had effects suspiciously similar to your sneak previews of Element. Are you beta testing in the broadcast world?

Hi Mr.Andrew....about Expressions? how can i identify the expressions? i mean make any expression my mind set to...i can't save them in my mind....how can u do that?
November 28th, 2011 @ 8:27 pm
Very cool.. I used your 108. tutorial to figure out what you did with that earlier machine gun sample like a year ago. So this is fantastic to see it used in such a tailored way and expanded on. Thanks so much!
November 28th, 2011 @ 10:27 pm
I was all like, "Hey! I'm going to try out that new awesome shattering orb tutorial Andrew Kramer made!" Then I got to the page and was like, "WHAAAT?!? Another one!" I know what I'm going to be doing now...

LK
November 29th, 2011 @ 9:24 am
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

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.

November 30th, 2011 @ 5:50 am
Kramer...cool 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.

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.

Regards
Jens

Wow Mr. Kramer ! I think you guys should make a plugin with this effect ! You rule ! Greetings from Denmark

December 7th, 2011 @ 1:02 am
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 we’re buying your great products!!!
Looking forward to buy VC Element 3D

THANK YOU. i remember asking you to do a 'tut' on this last summer.me 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
