Field Emitter

Field Emitter

Emit particles from a Field system.



Method #

This node emits particles from an input Field system, using the Colours, Density, or Temperatures passed through from the Field. The resultant particles can then pick up the location and velocities to flow along with the field, adding extra details and motion to an existing field or creating accurate fluid motion.

The transformation values of this node will be inherited by its children. Furthermore, Affectors, Shading, and Rendering nodes will only be effective to the particles emit by this emitter.


These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

RandomnessHow much randomness is added in the particles movement.
LifeControl how low long each particle exists for.
Life RandomnessControl the randomness for the life of each particle.
Emission RateWhat percentage of the particles are emitted from the emitter per second.
Max Particle CountSet a maximum particle count for the emitter.
Respawn EnabledToggle whether a particle can respawn.

Tints the particles colours from the emitter. To enable, add an colour ramp input to this node.

Colour Selection ModeChoose how the input colour affects the particles.
Colour Selection ParametersA number used to select the colour output.

These properties control the material the particles use for emission.

ColourRGB colour of particles.
DiffuseControl how much the light is scattered from the surface of the object.
EmissivenessControl how much light is emitted by the particle.
Life Colour Affecter WeightControls how much the result of any Life Colour Shading nodes are blended with the particle’s colour.
Particle ScaleScale the size of the particle.
Dof AmountHow much depth of field effects the particles material.
DensityThe density, for use in some simulations.
TemperatureThe density, for use in some simulations.
Cooling RateThe cooling rate, for thermal dynamics simulations.
Density DecayControl the rate of decay in the density.
Fade In TimeWhat percentage through the particles life span the particle fades in.
Fade Out TimeWhat percentage through the particles life span the particle fades out.
