DyEmitters - Square

This is an area emitter. An arrow indicates the node’s emission direction and helps you to point the emitter to a certain target. You can position (W key), rotate (E), and scale (R) this emitter.

Type

Toggle the emitter's type with this drop-down menu. The following parameters and the viewport representation will be updated according to your selection. Bear in mind that type changes will change the emitter's and fluid's behaviour completely.

Volume

This feature creates a defined volume of particles. The size of this volume is defined by the emitter’s horizontal → “Scale” settings and the vertical value entered here. All dimensions are given in metres. The particles will still have an initial velocity determined under "Speed". To avoid this, set "Speed" to 0.

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 the domain's “Resolution” settings. A value of 0.0 → stops the emission of particles.

V random

To avoid regular emission, it is possible to randomly displace the particles with these functions. The parameter accepts any value positive value and 0. “V” stands for vertical.

H random

To avoid regular emission, it is possible to randomly displace the particles with these functions. The parameter accepts any value positive value and 0. “H” stands for horizontal.

Side emission

Normally the particles are poured out along the emission axis, but it is possible to emit the particles from the emitter's edges. Then, the square's inner area remains empty.
