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.
Spline Object
Drag the spline object to this slot and convert it into an emitter. You need one emitter per spline.
Creation Type
Here are your options:
- "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 points. 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 point. 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.
Speed
Here the particles' initial speed is defined. 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 fluid's “Resolution” settings. A value of 0.0 stops the emission of particles.
Randomness
To avoid regular emission, it is possible to randomly displace the particles at creation time. Higher settings create more randomness. This parameter accepts all values between 0 and 50.
Thickness
This parameter is only available with "Creation" set to "Axis". Here, you control the thickness of the particle stream emitted from the spline's axis – this is also possible on a per-control-point basis (see "Thickness" below under "Control"). The unit is metres.
Avoid particle intersection
When enabled, Dyverso tries to avoid the creation of particles in areas where particles already exist.
Add Circle Control
A click on this button adds a new control point to the emitter and opens a new dialogue, where the point's attributes can be specified (see below). Each control point's attributes can be edited individually.
