Method

This Emitter emits particles only from objects within the cameras view. Particles can be emitted from other layers by adding a Render Layer node as an input to this node.

Example

Transform

Name Description
Position X Move its position along the x-axis in local space.
Position Y Move its position along the y-axis in local space.
Position Z Move its position along the z-axis in local space.
Rotation Heading Rotate the object about the x-axis.
Rotation Pitch Rotate the object about the y-axis.
Rotation Bank Rotate the object about the z-axis.
Scale X Scale along the x-axis.
Scale Y Scale along the y-axis.
Scale Z Scale along the z-axis.

Inherit Transform Channels

Toggle which transform channels should be inherited. By default, all are on.

Attributes

Name Description
Flip Image Flip the image input vertically.
Luminance Offset Scale Bias the particles in depth by the luminance of the source pixel.
Use Thickness Toggle whether emit the particles on a 2d plane, or in three dimensions.
Thickness Change the thickness of the three dimensional area the particles can spawn in. Only functions if “Use Thickness” is on.
Pixel Cull/Thickness Mode Change how the depth of the particle generation is calculated.
  • Alpha Channel, lower alpha values will have greater depth.
  • Luminescence, darker parts of the image will have greater depth.
  • Luminance * Alpha Channel, luminance values are multiplied by alpha values and lower values after which are given greater depth.
Alpha Threshold Limit where the particles will spawn based on their source alpha.
Image Colour Adaption How much the particle colours adapt to the image colours.
Particle Use Image Alpha Toggle whether particles use the image alpha.
Emission Velocity Normal Direction How great a velocity the particles are given in the normal direction of the object when spawned.
Limit Emissions Per Pixel Toggle whether the number of particles that can be emitted per pixel can be limited..
Max Emissions Per Pixel The maximum number of particles that can emit per pixels. Only functions if “Limit Emissions Per Pixel” is true.
Emission Area Min Control the minimum area that the particles will be emitted.
Emission Area Max Control the maximum area that the particles will be emitted.

Emission

Name Description
Emitter Active Change whether the emitter is on or off.
Randomness How much randomness is added in the particles movement.
Life Control how low long each particle exists for.
Life Randomness Control the randomness for the life of each particle.
Emission Rate What percentage of the particles are emitted from the emitter per second.
Max Particle Count Set a maximum particle count for the emitter.
Respawn Enabled Toggle whether a particle can respawn.

Colour Control

To enable, add an input into this node.

Name Description
Colour Selection Mode Choose how the input colour affects the particles.
  • Input Colour, The first colour input is the only colour output.
  • Selected Single Colour, Uses the colour selection parameter to decide which colour to use.
  • Emission Time, Colour is selected based on time at which the particle is emitted.
  • Random Colour, the colour is selected randomly at the particles creation.
Colour Selection Parameters A number used to select the colour output.

Video

Name Description
Motion Vector Effect Scales effect of motion vectors on the motion of the particles.
Time Offset Offset the time the effect is running.

Material

Name Description
Colour RGB colour of particles.
Diffuse Control how much the light is scattered from the surface of the object.
Emissiveness Control how much light is emitted by the particle.
Life Colour Affecter Weight Controls how much the result of any Life Colour Shading nodes are blended with the particle’s colour.
Particle Scale Scale the size of the particle.
Dof Amount How much depth of field effects the particles material.
Density The density, for use in some simulations.
Temperature The density, for use in some simulations.
Cooling Rate The cooling rate, for thermal dynamics simulations.
Density Decay Control the rate of decay in the density.
Fade In Time What percentage through the particles life span the particle fades in.
Fade Out Time What percentage through the particles life span the particle fades out.
