I am making a fire simulation, but I wanted to make the fire expand somewhat uniformly within a certain angle like a beam. Maybe the way to do this would be with obstacles? But I don't want to lose the little sparks/flares that come naturally out of the fire or to lose realism.
To illustrate it better, see this print of what I did, with a green sketch of the form I would like it to have instead:
Also, you can see that I used a normal force field and turbulence to control the direction and used a sphere for the fire emission.
Thank you in advance!
