HI, I am new to Maya and I was wondering if it is possible to emit a fluid from a particle? I am trying to make a realistic flamethrower. I got the flame part down but i can’t make it “throw” correctly. Any help would be great. thanks

as far as i know there is no integrated way in Maya to use particles as a fluid emitter.
I think you can script it though, but it will get really slow.

Look up the mel commands:
fluidvoxelInfo // Feed in the Particle Position and a radius und it will return the index of the voxels where the particle+radius is located.
for example: $emitVoxelMove = `fluidVoxelInfo -cb -r $radius -v ($pos.x) ($pos.y) ($pos.z) fluid1`;

setfluidattribute // use the resulting indexes to give the voxels certain amount of density or temperature or whatever.
for example: setFluidAttr -attribute “density” -fv $densityAmount -xIndex $emitVoxel[($a*3)] -yIndex $emitVoxel[(1+$a*3)] -zIndex $emitVoxel[(2+$a*3)] fluid1;

Don’t know if it helps you but maybe it is worth a try.
good luck

Thank alot for the help. I did some research and found this code and a video of what i want:

// get particle position
float $pos[] = particleShape1.worldPosition;

//find out which fluid voxel is at that position.
vector $voxel = `fluidVoxelInfo -voxel $pos[0] $pos[1] $pos[2] fluid1`;
$vX = $voxel.x;
$vY = $voxel.y;
$vZ = $voxel.z;

//get particle velocity
float $vel[] = particleShape1.worldVelocity;

//emit density and velocity in specified voxel.
setFluidAttr -at “density” -ad -fv 5 -xi $vX -yi $vY -zi $vZ “fluid1”;
setFluidAttr -at “velocity” -ad -vv $vel[0] $vel[1] $vel[2] -xi $vX -yi $vY -zi $vZ “fluid1”;

so you have the right idea. unfortunately for me I just started using expressions so everything i found and you wrote makes no sense to me, lol. I guess im getting ahead of myself. Im downloading books on mel and expressions so I should get up to speed soon. thanks.

You can now emit fluids from nParticles in Maya 2011.

Yes I’m really looking forward to the new fluid possibilities of Maya 2011 :)

Still, our current project uses maya 2009 and the workaround with the Mel commands is too heavy for my computer.I wonder how long the flamethrower from the video simulated

hope it works for you killa!
