Hi all,
I'm creating a small animation set in a really old, dusty cathedral and I was wondering what would be the best way to implement the effect of Dust floating all around. Kinda like this:

but all around.

Thanks

layering different types of noise patterns can work pretty well...
Some higH frequency masked by other high frequency, masked my a low freq. perlin noise then animate the noise patterns, color them, and mask that whole thing inside roto shapes to your desired area...takes some dialing but this works

Thanks for that but it sounds quite complicated, this is more what im looking for:

those little dust particles (plankton no doubt) floating in front of the camera. Can this be done in post production? or easily in max using animated masks?

My way would be in a compositing package shake or whatever you choose. . .

as long as your camera doesn't move too much you can get away with this method...

If you need to do it in 3d...Maybe play with an atmosphere shader on a volumetric light. . .

im not familiar with Max but you should be able create a Fx volume with only a handfull of points floting around. . .

alternatively u can use trapcode particular for ae or whatever ur compositing program is, its an excellent plugin, and cheap too.
cheers
