Paint Bleed/Water Effect

[Jerzy Drozda jr]

I think (I almost sure) that both of these clips was recorded with a camera. The color Ink was simply colorized in AE with a layer and blending mode set to hue or color.

Both are pretty possible to do i think using a particle system, but if you consider time needed to set this up and render it, it’s probably better to just get a tank and some ink and just record it with a camera.

Yes, that kind of thing is nearly always shot in a tank.

If you want to attempt to do something realistic in CG, you need a fluid simulation app such as Realflow, but that takes a fair bit of of money (if I recall) and a lot of horsepower to get renders out at a non-glacial pace. Since it’s so powerful, it also takes a fair bit of tweaking to get what you want. But it’s very realistic. But … I don’t even know if it’ll mix two fluids. Mr. Useful, that’s me. 😉

The “billowing smoke” look might be possible. You might be able to get something by using a regular 3D app using some kind of particle/hypervoxel simulation, or maybe with particle Illusion or Particular in AE.

you could just buy it too….

Blender has a half decent fluid simulator. And its free.
You just have to learn it.

Artbeats has some great stuff. What you pay is what you get!

thank you all

sorry this is a little late, but Andrew Kramer has some pre matted ‘ink flows’/’paint drops’ in his Riot Gear dvd on videocopilot.net I have used these effects from time to time. they come in quite handy.

Yes, I know Riot Gear. I actually do use it, but I just though about the way it could be made, ’cause there are only a few of them on the Riot Gear DVD and not much on the web.
