Water in after effects….again
Hello everyone!
I was wondering if in After Effects alone, you could have water “pouring” onto other objects, then based on the size and shape of the object, the water’s direction is changed. Think of pouring water onto hands, or fresh fruit, how different the speed, direction and shape it would be after contact with an object. Is there a way to do this with a particle generator, or should I be looking to a 3D program instead? Any info or links would be appreciated!Cheers!

Sorry, you need a 3D app for that.
Many apps should be able to handle it, but for realistic results, you might want an app called Realflow. It ain’t cheap or simple, though.

Thanks Steve, I may try something with CC Particle World, although I can already see the results won’t be anything amazing.

Foam can use an alpha channel (from any layer) to influence the flow of the particles but interaction with the alpha edges is not very realistic.
The floor of the CC Particle World will work but it is only one flat surface.You need to forget trying to simulate this in AE (or get appropriate plugins) or consider working within AE’s limitations but use them as your approach to stylization. Figure out what you can do and then design your sequences around the available tools.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

Geez, even in the 3d world this is something highly complex and exotic. Like Steve said, Realflow is pretty much what you would need (or Houdini’s or Maya’s fluids).

Mylenium’s right, and there are guys who specialize in this fluid dynamics stuff. And the render times for Realflow can be glacial, since you’d be doing a fluid dynamics simulation.
But if you’re stuck with AE, it has to be stylized, as bogesian recommended.

Thanks for the advice, I don’t think the project’s budget is big enough for the software, so I’ll go for a stylized approach.
Cheers,

shoot it against black, monkey with the levels, then precompose & use unmult to create the alpha. We did this just a few weeks ago.

Agreed, shoot the water live on black. (Be sure to use a good lighting setup…a Dedo would be best to get the most directional lighting) To achieve the motion (action) of the water use real objects ie – hands/fruit. THEN, use AE’s power to stylize and clean up. Masking, duplicating then offsetting certain parts of the water should able you to repair any areas that don’t alpha too clean.
