Image : Emission
- thomas (Unlicensed)
“Image” lets you either load a single image or an entire image sequence as an emission mask. The viewport gizmo represents the size of the emission area. 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; an arrow indicates the direction of emission.
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.
Volume
This feature creates a defined volume of particles. The size of this volume is defined by the emission area and the value entered here. The parameter is connected to Cinema 4D's scale settings.
Speed
Here the particles' initial speed is defined in metres per second. 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.
Vertical Random
To avoid regular emission, it is possible to randomly displace the particles with these functions. The value's range is between 0 and 1.
Horizontal Random
To avoid regular emission, it is possible to randomly displace the particles with these functions. The value's range is between 0 and 1.
Texture
Create or open a material and drag an image or a shader from the "Texture" field to this slot:
- The emitter only uses the image's purely white parts for the emission – grey shades are not considered.
- Cinema 4D's built-in procedural shaders (e.g. noise) are supported.
