“Sphere” is a volume emitter. Emitters define the point of particle creation in 3D space, while the particles are part of the "Fluid" container. Emitters can be scaled, rotated, and translated like objects.
RealFlow Scene
In RealFlow | Cinema 4D it is possible to use multiple "Scene" trees in the same project:
- To link the emitter to a different scene tree dragging the appropriate "Scene" node to this field
- Furthermore you have direct access to the selected "Scene" tree's → "Solver", → "Cache", and → "Display" tabs. For descriptions of these parameters follow the links.
Linked Fluids
RealFlow | Cinema 4D 3 supports interactions between different "Fluid" domains, e.g. for the creation of foam or water-and-oil simulations:
- To link the emitter to a "Fluid" node drag the "Fluid" node(s) to this field.
Emitter Type
Toggle the emitter 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.
Fill Volume
There are two options:
- When enabled the viewport gizmo's volume is filled with particles.
- When disabled particles will be emitted from the sphere's surface.
Speed
Here the particles' initial speed. Higher values will generate more particles per frame. The number of emitted particles also depends on the fluid's → “Resolution” settings. A value of 0.0 stops the emission of particles.
Randomness
Use this option to avoid patterns and regular structures by displacing the particles randomly at creation time. The value's range is between 0 and 50.
