Procedural Emitter
Updated: 4 Dec 2023
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 To Alpha
Controls 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.
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.
Inputs
These properties control the core behaviours of the node.
