TParticleSystemSettings
template<bool IsRenderProxy>Templated common base for both main and render thread variants of ParticleSystemSettings.

Fields
Duration
Determines the time period during which the system runs, in seconds.
This effects evaluation of distributions with curves using particle system time for evaluation.
IsLooping
Determines should the particle system time wrap around once it reaches its duration.
MaxParticles
Determines the maximum number of particles that can ever be active in this system.
This number is ignored if GPU simulation is enabled, and instead particle count is instead only limited by the size of the internal buffers (shared between all particle systems).
GpuSimulation
If true the particle system will be simulated on the GPU.
This allows much higher particle counts at lower performance cost. GPU simulation ignores any provided evolvers and instead uses ParticleGpuSimulationSettings to customize the GPU simulation.
OrientationLockY
Determines should the particles only be allowed to orient themselves around the Y axis, or freely.
Ignored if using the Plane orientation mode.
OrientationPlaneNormal
Determines a normal of the plane to orient particles towards.
Only used if particle orientation mode is set to ParticleOrientation::Plane.
SortMode
Determines how (and if) are particles sorted.
Sorting controls in what order are particles rendered. If GPU simulation is enabled only distance based sorting is supported.
UseAutomaticSeed
Determines should an automatic seed be used for the internal random number generator.
This ensures the particle system yields different results each time it is ran.
ManualSeed
Determines the seed to use for the internal random number generator.
Allows you to guarantee identical behaviour between different runs. Only relevant if automatic seed is disabled.
UseAutomaticBounds
Determines should the particle system bounds be automatically calculated, or should the fixed value provided be used.
Bounds are used primarily for culling purposes. Note that automatic bounds are not supported when GPU simulation is enabled.
CustomBounds
Custom bounds to use them is disabled.
The bounds are in the simulation space of the particle system.
