This is a 3-dimensional emitter. You can position (W key), rotate (E), and scale (R) this emitter, but the scale parameters are linked and it is not possible to create oval shapes.
Speed
Here the particles' initial speed is defined in metres per second. Higher values will generate more particles per frame. Faster particles act with stronger forces on other particles or objects. The number of emitted particles also depends on your → “Resolution” “Resolution” settings. A value of 0.0 disables the emission of particles.
