how to emit fluids from nParticles?

[Phlok]

Hi,

I haven't got the time to look up the commands, but it should work the following way:

- Check wicht Voxel(s) your particles is passing.
- Add (e.g.) density at the voxel's position.

Thx man I knew that it will be with MEL :>.Will check for the commands :>.

Wow thx just the thing that I need :>.Its time for reading :>.

vector $pos = particleShape1.position;
int $voxels[] = `fluidVoxelInfo -v ($pos.x) ($pos.y) ($pos.z) fluid1`;

if (`fluidVoxelInfo -ib ($voxels[0]) ($voxels[1]) ($voxels[2]) fluid1`) {
setFluidAttr -at "density" -fv 1 -xi $voxels[0] -yi $voxels[1] -zi $voxels[2] fluid1;
}


This code pretty much simplifies that whole thread.

As long as you are simplifying things could you also tell me where to plug this script in? :)

I think its expresion that you have to write in expression editor,but 1st you have to set it to "Runtime before Dynamics".
Thx all it works preaty good :>.

This is what I tried to do. Keep getting this error:
// Error: Attribute of a particle object can only be used with dynExpression command: position //

Its work for me and this is what I did:
1: Made particle emitter and 3d fluid container.
2: Go to Per Particle Attributes and right click on position->Runtime expression before Dynamics...
3: Paste the code and hit edit :>.
Have to work now :>.

Edit: Probably you use nParticles :>.To make them work just change
vector $pos = particleShape1.position; to vector $pos = nParticleShape1.position;
and it will work :>.
Hope this will help you :>.

That worked. Thanks a lot.

vector $pos = particleShape1.position;
int $voxels[] = `fluidVoxelInfo -v ($pos.x) ($pos.y) ($pos.z) fluid1`;

if (`fluidVoxelInfo -ib ($voxels[0]) ($voxels[1]) ($voxels[2]) fluid1`) {
setFluidAttr -at "density" -fv 1 -xi $voxels[0] -yi $voxels[1] -zi $voxels[2] fluid1;
}

:surprised wow man....

amazed
