Spline Emitter

Spline Emitter

Emits particles from a spline.

Method #

This node emits particles from a spline shape. The splines used by this node are extracted from a 3D object which must be connected to the Object Nodes input for this node to have an effect. If The object that is connected contains no spline data this node will have no effect.

Requires a Spline input to function.

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.

Parameters

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.

ParameterDetails
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.

ParameterDetails
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.

ParameterDetails
RadiusThe radius around the spline at which the particles will be emitted.
Radius RandomnessThe randomness of the radius around the spline at which the particles will be emitted.
Spline Time MinThe minimum point on the spline at which particles will be emitted.
Spline Time MaxThe maximum point on the spline at which particles will be emitted.
Initial Spline Direction VelocityThe magnitude of the initial velocity assigned to particles in the tangential direction of the point on the spline at which they are emitted.
Initial Spline Normal VelocityThe magnitude of the initial velocity assigned to particles outwards from the point on the spline at which they are emitted.
Follow Spline AmountThe velocity along the spline applied to particles after emission towards the particle’s goal point on the spline, which starts at the point they are emitted from.
Follow Spline RateThe rate at which the particle’s goal point moves along the spline.

These properties control how the particles are emit from the node, and thier core life properties.

ParameterDetails
Emitter ActiveChange whether the emitter is on or off.
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.

These properties control the material the particles use for emission.

ParameterDetails
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.
