The "Image” emitter 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.

 

 

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 Maya'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.

Map

Create or open a material and drag an image or a shader from the "Texture" field to this slot:

  • Only areas with color/grey scale values greater than 0 will be used for emission
  • With RGB images the red channel will be used.
  • Grey scales will be treated as purely white areas (= full emission).
