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 |
|
Input operators to use in this system. |
|
active |
|
Activate operator stack processing. |
True |
maxparticles |
|
Maximum particles to maintain. |
100 |
samplingRate |
|
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 |
|
0 – local playback; simulate independent of timeline 1 – Timeline playback; simulate based on global timeline |
0 |
localPlaybackState |
|
0 – Playing 1 – Paused 2 – Stopped |
0 |
localPlaybackPeriod |
|
Duraction of playback period when in local playback mode |
4.0 |
playbackStartTime |
|
The start time of the simulation in playback mode. |
0.0 |
playbackEndTime |
|
The end time of the simulation when in playback mode. (Negative value indicates endless evaluation.) |
-1.0 |
seed |
|
Seed for random number generation. Keep in mind that determinism shouldn’t be expected for varaiable dt, ie in non-playback mode. |
123 |
exportAttributes |
|
Comma delimited list of particle attributes to export from the simulation. |
position,velocity,aim,color |
onDeathEvent |
|
Populate onDeath export with particle payloads that have been deleted on current frame. |
False |
onBirthEvent |
|
Populate onBirth export with particle payloads that have been emitted on current frame. |
False |
onMoveEvent |
|
Populate onMove export with particle payloads that have changed position on current frame. |
False |
onCollideEvent |
|
Populate onCollide export with particle payloads that have experienced collision on current frame. |
False |
