Particle 3D Emitter
Method #
This node emits a particle system into a 3D field.
Parameters
Parameter Details Particle Radius The particle radius.
Density The amount of density to emit.
Temperature The amount of temperature to emit.
Velocity Scale 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.
Emit Once If enabled, emit only once on the first frame the emitter is active. otherwise emit continuously.
Parameter Details Noise Amount The amount of fractal noise to apply to the emitted density.
Noise Scale The scale of the fractal noise.
Noise Threshold The threshold to apply to the fractal noise.
Parameter Details Explode If enabled, the emitted areas will have an initial explode velocity injected with the given parameters.
Explode Velocity The explode velocity.
Explode Velocity Noise Scale The scale of the fractal noise used to generate the explode velocity.
Explode Velocity Noise Threshold The threshold to apply to the fractal noise used to generate the explode velocity.
Parameter Details Pyroclastic Displacement Enabled If enabled, the emitted areas will have pyroclastic displacement applied, giving them a more turbulent, cloud-like shape.
Pyroclastic Displacement Amount The amount of pyroclastic displacement.
Pyroclastic Noise Scale The scale of the fractal noise used to generate the pyroclastic displacement.
