how do i make this scence~edit each gravity of emiters in Fluid?http://bbs.hxsd.com/attachment.php?attachmentid=868086&d=1273223631

If you wish to make a fluid fall, rather than rise upwards, set a negative value on buoyancy.
Buoyancy is set on the container, so each emitter for the container will behave the same.

But i have two emitters.If i set a negative value on buoyancy,all the emitters will behave the same path.i want make each emitter do the different path without the same Fluid environment.Like the pic..

I do not see a reference picture.

If there is no need for interaction, use two containers.
If they must be in the same container, try emitting from an animated geometry that moves along each path to drive the shapes you need.

You could make the density buoyancy -1 and the temperature buoyancy 2. (also make temperature dissipation,diffusion,turbulence all zero and make the temperature grid dynamic). Have one emitter emit with zero temperature and the other with. Do a blue red ramp and color and make temperature the input. Make the incandescence ramp all black.

two containers can make colide?how can i do this ?^_^

You can collide objects with multiply fluids by simply doing make collide for each fluid.
You can't collide two fluids with each other( although it is ambiguous what this would really mean ). However you can use a fluid a field applied to a second fluid, which can allow some interaction. (applying each as a force affecting the other would create a dependency graph loop and might not work well)

In general, however, I would recommend trying to use a single fluid if possible.
