filtering light

[Malcolm Desoto]

Also, I’d like to create some dust in the air in order to create a kind of atmosphere. I’m working with still images here. I’m planning on doing this with the particle generator.

If you have any tips on how the dust could interact with the light (ie making the light shine through the dust or high light certain particles) that would be very helpful.

I’ve never really tried anything like this so I’m just doing alot of experimenting at the moment.

I’m having a bit of trouble creating this. I realize the air debris in this clip may have been created in a 3D app, but I’m trying to get something similar.

Did you try searching for “particular” and “dust”? I seem to recall that this has been covered here before.

[Malcolm Desoto]

I haven’t searched under “particular” But I did try “dust”
I’ll try the previous to see what results are yielded.

Yeah, it does seem like it’s been covered before. I thought there would have been a tutorial or something.

Oh well, I continue my search…

Serge has a nice tut here that could get you going:

You’re a saint!

Is there a tutorial for that vid?

Sorry if I’m being dense.

Just to complicate things…

I just remembeed, Foam is a nice particle generator for bubble and, yes… dust. You just need to use a “Dust Particle” you make yourself.

Foam Settings:

View: Rendered

Rendering>Bubble Texture>User Defined

BubbleTexture Layer: Choose a “Dust Particle” layer you’ve created in AE (a jagged mask on a 128×128,white solid, precompose it so Foam sees the mask, otherwise you get a white block), Paint Spot or Photoshop, say 128×128. Turn off the eyeball of the layer or precomp, it just to be referenced to be used by Foam.

You can even make a Flow Map to channel the particles, a White Solid, with a mask. The White repels or limits the particles, the Black (masked area) allows free passage. Again Precompose, and turn off the eyeball in the main comp, just reference the layer (I named mine “flow”).

Foam>Flow Map>Flow Map: and from the drop down, choose “3.flow Comp1” or you layer.

There are lots of tweaks for Direction, Wind, and Turbulence to give your dust that floating look.

It seems that I am only able to dl a .sit file?

I think I pretty much got the dust aspect of this project handled now anyway. Thanks!
