money rain

[Steve Roberts]

If you want your cash to bend, float and look realistic, you have to use a 3D app.

(Forge Freeform would require you to animate each bill by hand)

However, if you’re willing to put up with flat money, you might try Trapcode’s Particular and set up some turbulence therein. But a 3D app is the choice for realism.

the only 3d application we can use is cinema 4d…but I really don’t know how to start this project in an 3d app…i know with after effects i can’t do it very well but perhaps there are some tipps how i can add the money notes into the scene a little bit more realistic….is it possible to add 3d depth by duplicating the money layer a few times and changing it’s z-position?
thanks

Is particle playground still under simulation? Haven’t looked for that in years!! You could tie an image to those particles…

Also — here’s an interesting script that will simulate a falling paperish object:

Well — I couldn’t find the one I was looking for… but this might help you too:

Sure, dupe the money layer and shatter each one. However, you can’t move the shatter layer, only the camera, if I recall. So you might need to render three times, each with a different camera switched on, then combine the three renders in a comp.

Anybody else?

Why not precompose one dollar note in 3D space twisting around and then use the layer as a particle in trapcode particular? So, everything would be done in AE.

This is the way, I could imagine it to work…

If you have Trapcode particular you could check out this .aep from http://www.trapcode-people.com:

I did a short version of this effect years ago for a news item. Take 20 bills, and drop them in front of a green/blue screen. So much easier than 3D apps or even a particle system.

Once you’ve got some footage, key it and duplicate it. Or film a bunch of drops. You can also get away with dropping the bills against a black background if you don’t have enough green material.

Dan has a nice Snow Falling Composition in his tutorial “Building a 3D Particle Generator”.
You can swap your Money Pic for his Snow psd and have 3D Money raining down in no time, all highly tweakable. Click on Dan Ebbert’s head(at top of page) then scroll down to, “Building a 3D Particle Generator” and download the project aep.

In AE close all the comps, except “Snow”.

I’d dup the comp and rename it “Money”, then close snow (unnecessary step really).

Anyway, in the old Snow or new Money comp, select all the snow layer except 1 and Delete.
That leaves 3 layers,

1 – snow_1.psd
2 – Null 1
3 – AE 5.x Default Camera

Import your Money Picture (psd?), note Dane’s particles are psd files that are 128×128 pixels , so if the size is right in his comp, make your money that size (or 128 wide) or adjust as needed.

Select the only snow layer left, snow_1.psd, and while holding down the Alt key, place your Money Pic ontop of the snow_1.psd layer. This should replace the snow layer with your money layer, keeping all the attributes of the old snow layer (all that god code Dan wrote).

Now Dup the layer (Ctrl D) as many times as you want Dollar Bills.

Note, this is 3D, so if you mask off your pilings, and make that layer and the background 3D, you can have the money raining down in front of and behind the Pilings.

I love Dan’s 3D particle Generator, it’s not Particular or Particle Illusion, but is great for small stuff, and is true 3D.

Note: You can control lots of things about Dan’s particles.

Select a Particle layer, hit “ee” to see the expressions, some things you can control are:

Point:
minimum particle life
maximum particle life

Position:
gravity
wind direction
emitter width

Orientation:

Z Rotation

Read Dan’s Tutorial “Building a 3D Particle Generator” he goes into detail.

Note 2: To get this into your project without bringing in all Dan’s Comps , you can reduce the project.

In the project window, Select the Comp with the money (Snow or Money).

File>Reduce Project.

Now save the project with a name like “RainingMoney”, then in your project Import the File RainingMoney.aep

Found the one I was thinking about…again by Mr. Ebberts… Dan — I’m just down the road from you… mind if I sit in your mind for a few days?

Though I think the other one is easier…

A falling leaf can be a pretty complicated simulation – sometimes they just
fall gently, sometimes they do barrel-rolls, sometimes glide back and forth, or
any combination. These expression roughly simulate the glide back and forth
variation. I tried this on a 3D solid positioned above the camera view,
oriented with Z pointing down and Y pointing in the positive Z direction
(orientation [90,0,0]).

Then I added these three expressions:

POSITION:

yVelocity = 200; //pixels per second
oscFreq = 1.5; //oscillations per second
oscDepth = 35; //oscillation depth (pixels)
drift = 25; // drift (wind?) (pixels per second: – = left, + = right)

value + [oscDepth*Math.sin(oscFreq*Math.PI*2*time) + drift *time,
yVelocity*time,0]

Z ROTATION:

seed_random(index,true);
random(360);

Y ROTATION:

oscFreq = 1.5;
maxTilt = 15; //degrees

maxTilt*Math.cos(oscFreq*Math.PI*2*time)

If you edit the parameters, you need to make sure that the oscillating
frequency is the same in both the position and y-rotation expressions (or map
it to a slider control). If you wanted to apply this to a bunch of leaves,
you’d want to introduce some randomness into the various parameters along with
a random starting phase.
