System Management rollout
Use these settings to limit the number of particles in the system, and to specify
the frequency of updating the system.
Particle Amount group
Upper Limit The maximum number of particles the system may have.
Default=100000. Range=1 to 10000000.
TIP You can have more than 10,000,000 particles in a single system by using
multiple particle sources and wiring them to the same birth event. Note, however,
that Particle Flow is limited to sending a maximum of 5,000,000 particles per
event to the renderer.
Integration Step group
At each integration step, Particle Flow updates the particle system, applying
each active action to particles in its event. A smaller integration step can
improve accuracy, at the cost of calculation time. These settings let you apply
different integration steps to the particle animation in the viewports and at
render time.
In most cases, the default Integration Step settings work fine. One instance
in which increasing the integration-step frequency might help is when
fast-moving particles that should collide with a deflector penetrate it instead.
Viewport Set the integration step for animation playback in the viewports.
Default=Frame (once per animation frame). Range=1/8 Frame to Frame.
Render Set the integration step at render time. Default=Half Frame (twice per
animation frame). Range=1 Tick to Frame.
There are 4,800 ticks in a second; thus, at the NTSC video rate of 30 frames
per second, there are 160 ticks per frame.
