Procedural Emitter
Updated: 15 Sep 2026
Emits ink into a field from procedurals.
Procedural Emitter
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.
Parameters
These properties control the core behaviours of the node.
Parameter Details Distance -> Alpha
How quickly emitted geometry fades with distance from the emitter, remapped into the particle alpha.
Emission Mode
When to emit.
Colour
The colour to emit.
Density Emission
How density is applied to the system
Density
The amount of density to emit.
Fuel Emission
How fuel is applied to the system
Fuel
The amount of fuel to emit.
Temperature Emission
How temperature is applied to the system
Temperature
The amount of temperature to emit.
Velocity Emission
How velocity is applied to the system
Velocity
The amount of velocity to emit.
Hardness
Reduces the emission rate around the edges of the emission area to create softer looking edges.
Pyroclastic Displacement
The amount of pyroclastic displacement.
P Noise Scale
The scale of the fractal noise used to generate the pyroclastic displacement.
P Noise Scale
The scale of the fractal noise used to generate the pyroclastic displacement.
Parameter Details Baked Shader
The compiled internal shader used by the procedural emitter. Drag an FX shader resource here to replace the built-in behaviour.
The properties control the time at which the node is active. See Timeline for editing time segments.
Parameter Details Duration
Control the duration of the node’s time segment.
- Composition Duration : Use the length of the composition for the node’s time segment duration.
- Custom : Set a custom duration for the node’s time segment.
Node Time
The custom start and end time for the node.
Duration (Timecode)
The length of the node’s time segment (in time).
Duration (Frames)
The length of the node’s time segment (in frames).
Time Segment Enabled
Set whether the node’s time segment is enabled or not in the Timeline.
