"Linear" is a two-dimensional emitter in the shape of a straight line. Therefore it is not possible to alter any height information: only length can be changed. Particles are emitted in the direction of the green arrow from the “underside” of the line. The result is a thin, curtain-like stream of fluid.

Height

This parameter has nothing to do with the emitter’s physical height, but is comparable to “Volume” and creates a rectangle filled with particles. When “Height” is adjusted to any value other than 0, “Speed” becomes disabled. The parameter is given in metres [m].

Length

We recommend to change the emitter’s length with this parameter, instead of using the scale settings under "Node". "Scale" is available, but works like a multiplier, if “Length” is activated: an emitter with “Length” = 3.0 and “Scale X” = 2.0 has a total length of 6 units. The value is given in metres [m].

Speed

Here you can define the speed of the particles at creation time. Please remember that higher speed values create more particles. This value is measured in metres per second [m/s].

V/H random

These settings add a certain amount of randomness to the particles to avoid patterns.
