Syntax

class UParticleLODLevel : public UObject

Variables

	Name	Description
uint32: 1	bEnabled	True if the LOD level is enabled, meaning it should be updated and rendered.
uint32: 1	ConvertedModules
UParticleModule...	EventGenerator	The optional EventGenerator module.
TArray< class U...	EventReceiverModules	Event receiver modules only!
int32	Level	The index value of the LOD level
TArray< class U...	Modules	An array of particle modules that contain the adjusted data for the LOD level
TArray< class U...	OrbitModules	OrbitModules These are used to do offsets of the sprite from the particle location.
int32	PeakActiveParticles
UParticleModule...	RequiredModule	The required module for this LOD level
TArray< class U...	SpawningModules	SpawningModules - These are called to determine how many particles to spawn.
UParticleModule...	SpawnModule	The SpawnRate/Burst module - required by all emitters.
TArray< class U...	SpawnModules	SpawnModules - These are called when particles are spawned.
UParticleModule...	TypeDataModule	Module used for emitter type "extension".
TArray< class U...	UpdateModules	UpdateModules - These are called when particles are updated.
