This emitter creates particles and moves them through a force field along a customizable path. Emitters define the point of particle creation in 3D space only, while the particles are part of the domain. Here is how to create and edit such an emitter:
...
Very nice effects can be achieved with animated splines, e.g. a "Cycloid" with an animated "End Angle".
The parameter set has one two subcategory:

...
- "Axis". The particles are created along the spline's path similar to a curtain. Emission direction is indicated in the viewport through small arrows at the spline's control pointscircles. This direction can be changed with "Rotation" (see "Control" below).
- "Tube" The particles are created along the spline's path. The fluid tube's thickness is defined through the circles at each control pointcircle. As with "Axis", emission direction is indicated through small arrows.
- "Edge". The particles are created at the first control point and moved along the spline through customizable forces. The first point's circle represents the area of emission.

When enabled, Dyverso tries to avoid the creation of particles in areas where particles already exist.
Control
Add Control Circle
Add a new control point after the selected control point.
Delete
Delete the selected control point.
Previous | Next
Click on these buttons for selecting the previous or next control point.
Offset
You can change the selected control pointcontrol circle.
Default
Reset all the existing control circles nodes attached to the spline emitter to default values.
Reset
Remove al existing control circles and create a new ones with default values.
Helper
When enabled the direction and strength of emission is displayed in the viewport. If you change the emitter's parameter, e.g. "Speed" or "Rotation", the gizmo will be updated accordingly.
Spline Control Circles Nodes
Spline control circles nodes are used to control the particle emission from the spline.
Segment
Determines in which segment of the spline you want to place this control circle (only use for spline with more than one segment).
Offset
Control circle's position on the spline with this value, e.g.
- 0.0. The control point is moved to the spline's start.
- 0.5. The control point is moved to the spline's midpoint.
- 1.0. The control point is moved to the spline's end.
Radius
The circle around a control point indicates the forces' scope or radius. Only particles inside the viewport's circles will be affected. The circles' sizes can be controlled with this parameter or the viewport gizmoDetermines the fluid stream's thickness when Emission > Creation is set to "Tube" or "Edge". You can use the viewport gizmo as well.
Speed
When the emitter is in "Axis" or "Tube" mode it is possible to define different emission speed values for every control point separately:
- 0 stops the creation of particles at this control pointcircle.
- The adjusted is value will be multiplied with the global "Speed" value under "Emission".
- The parameter is connected to Cinema 4D's scale settings.
...
It is possible to control the thickness of the emission per control point. The final value will be CP thickness * Thickness.
Helper
When enabled the direction and strength of emission is displayed in the viewport. If you change the emitter's parameter, e.g. "Speed" or "Rotation", the gizmo will be updated accordingly.
