Procedural Emitter

Procedural Emitter

Emits ink into a field from procedurals.

Method #

This node emits colour/ink into a field using a procedural system.

A Procedural root must be connected to the Procedural Root input with a valid procedural generated for this node to emit anything.

The outputs from this node are just its transforms, useful for having multiple nodes follow the same motions without controlling each of their transforms individually.


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.

Distance To Alpha ScaleControls how the distances defined by the procedural system are converted into transparency values in the field - which is analogous to the density of the shape.
Blend AmountHow much the emitter blends with the field.
Blend ModeHow the emitter blends into the field. See Blend Modes for details.
  • Solid : The emittedd ink replaces all the field.
  • Linear : The emittedd ink is blended with the field.
  • Additive : The emittedd ink is blended with the field.
  • Subtractive : The emittedd ink is subtracted with the field.
