ParticleSystem

Particle system manager node.

Installation

To use this Node, you must enable omni.particle.system.core2 in the Extension Manager.

Inputs

Name	Type	Description	Default
operators	bundle	Input operators to use in this system.
active	bool	Activate operator stack processing.	True
maxparticles	int	Maximum particles to maintain.	100
samplingRate	float	If less than one, 1/samplingRate prescribes the number of substeps taken per frame; If greater than one, the whole number component of samplingRate prescribes how many frames run between simulation steps.	1.0
playbackMode	int	0 – local playback; simulate independent of timeline 1 – Timeline playback; simulate based on global timeline	0
localPlaybackState	int	0 – Playing 1 – Paused 2 – Stopped	0
localPlaybackPeriod	float	Duraction of playback period when in local playback mode	4.0
playbackStartTime	float	The start time of the simulation in playback mode.	0.0
playbackEndTime	float	The end time of the simulation when in playback mode. (Negative value indicates endless evaluation.)	-1.0
seed	uint	Seed for random number generation. Keep in mind that determinism shouldn’t be expected for varaiable dt, ie in non-playback mode.	123
exportAttributes	token	Comma delimited list of particle attributes to export from the simulation.	position,velocity,aim,color
onDeathEvent	bool	Populate onDeath export with particle payloads that have been deleted on current frame.	False
onBirthEvent	bool	Populate onBirth export with particle payloads that have been emitted on current frame.	False
onMoveEvent	bool	Populate onMove export with particle payloads that have changed position on current frame.	False
onCollideEvent	bool	Populate onCollide export with particle payloads that have experienced collision on current frame.	False

Outputs

Name	Type	Description	Default
onDeath	bundle	Particles that have been deleted in this frame. Activate on death event flag to populate.
onBirth	bundle	Particles that have been emitted in this frame. Activate on birth event flag to populate.
onMove	bundle	Particles that have been chnaged position in this frame. Activate on move event flag to populate.
onCollide	bundle	Particles that have experienced collision in this frame. Activate on collide event flag to populate.
exports	bundle	All Particles in current frame. Per-particle attributes enumerated in exportAttributes field.
