emit particles into fluids

Krakatoa for Maya
1

Does anyone know of an efficient way to emit particles into a Maya fluid based on the density of the voxels?

I can do it with an expression that loops through all the voxels querying density, but that takes an enormous amount of time -especially once the fluids get to be a decent resolution.

FumeFx and Phoenix FD have fluid particle emitters that are very fast, just wondering if anyone knows of a good way to do the same in Maya without those tools.

Thanks in advance.

I’m not sure of a way to do that in Maya. This problem may be solved when we add support for Maya Fluids within Krakatoa, because we would be seeding particles onto the voxel grid. Is that what you are looking for?

It is.
I did find a way to optimize it quite a bit. Thank you though.
I look forward to seeing what you guys come up with…

well its pretty simple,
you have to connect the particle emitter to the fluid in the dynamic relationships.
To start use the standard particle system. For nparticle you have to change some parameters to avoid oposite forces.

I don’t think we’re talking about the same thing here. Are you referring to using the fluid as a field for the particles?
