Emits ink into a field from particles
Particle 3D Emitter
Method #
This node generates colour/ink based on the positions and movement of particles from a particle system. The particles contribute both ink and velocities to the field.
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 Particle Radius The particle radius.
Emission Mode When to emit.
Colour The colour to emit.
Density The amount of density to emit.
Temperature The amount of temperature to emit.
Velocity The scale of the velocity to emit. velocities are generated from particle motion; a velocity scale of 1 emits the particle’s velocity as-is.
Hardness TBC
Fractal Noise Amount The amount of fractal noise to apply to the emitted density.
F Noise Scale The scale of the fractal noise.
F Noise Threshold The threshold to apply to the fractal noise.
Explode Velocity The explode velocity.
E Noise Scale The scale of the fractal noise used to generate the explode velocity.
E Noise Threshold The threshold to apply to the fractal noise used to generate the explode velocity.
Pyroclastic Displacement The amount of pyroclastic displacement.
P Noise Scale The scale of the fractal noise used to generate the pyroclastic displacement.
