This emitter creates particles and moves them through a force field along a customizable path. The path can be created in RealFlow's viewport directly, imported as a → SVG, or copied from an already existing → spline node. The spline's viewport representation is controlled with the → “Display Spline” panel.
Affect
With “Force” it takes a little time to display the daemon's full influence and the result is a curved stream of particles. “Velocity” directly affects the particles from the very beginning without any delay or acceleration, and you will get a linear particle stream. “Velocity” is not available for rigid/soft bodies.

Click on “EDIT” and select a control point to change the parameter's settings. The circle around indicates the forces' scope or radius. Only particles or rigid/soft bodies inside the viewport's circles will be affected. The circles' sizes can be controlled with the yellow dot: hit the R key, select one or more dots, and move it.
@ CP speed
Click on “EDIT” and select a control point to change the parameter's settings. When the emitter is in "Axis" or "Tube" mode it is possible to define different emission speed values for every control point separately. This parameter is given in metres per second and accepts all positive values including 0.
@ CP rotation
Click on “EDIT” and select a control point to change the parameter's settings. Every control point of the emitter has a small turquoise arrow, indicating the fluid's emission direction in "Axis" and "Tube" mode. By entering a positive degree value this emission direction can be changed.
@ CP link
Every control point can be linked to another node, e.g. to animate a point's position. Normally, “Null” nodes are used for this purpose, but any other node will work as well. Simply click on “-” to open a node list.
...
With “Smooth” both tangents are affected while moving a single handle. When you switch to “Broken” the tangents can be edited separately.
@ CP handle
...
weighting
When set to “Even” both tangents have the same influence on the spline's curvature. With “Uneven” the tangents' influence is treated individually.
