3D Wind Tunnel Horizontal

[ZayonXY]

I was looking for some way to simulate a Wind Tunnel and found a very old video teaching how.

I followed it step by step, but as the video is very old something didn't work out.

I made some changes to the code and it worked a little, but I still can't edit the variables (like wind speed and the amount of tracers). I don't understand anything about programming.

With the changes I made, it looked like this:

float $vel = fluidEmitter1.windSpeed;

int $tracers = fluidEmitter1.tracers;

int $yres = fluidShape1.resolutionH;

int $zres = fluidShape1.resolutionD;

float $density = 3;

setFluidAttr -at velocity -xi 0 -vv $vel 0 0 fluidShape1;

int $i;

for($i=0; $i<$tracers; $i++ )

{

int $yIndex = $yres * (($i + 0.5)/$tracers);

int $zIndex = $zres * (($i + 0.5)/$tracers);

setFluidAttr -at density -xi 0 -yi $yIndex -zi 15 -fv $density fluidShape1;

}

If anyone can help me...
