[edit] Properties
[edit] Property group 'Bounds'
[edit] bUseFixedRelativeBoundingBox
Type: bool
Whether to use the fixed relative bounding box or calculate it every frame.
[edit] FixedRelativeBoundingBox
Type: Object.Box
Fixed relative bounding box for particle system.

[edit] Property group 'LOD'
[edit] LODDistanceCheckTime
Type: float
How often (in seconds) the system should perform the LOD distance check.
Default value: 5.0
[edit] LODDistances
Modifiers: editfixedsize
The array of distances for each LOD level in the system. Used when LODMethod is set to PARTICLESYSTEMLODMETHOD_Automatic.
Example: System with 3 LOD levels LODDistances(0) = 0.0 LODDistances(1) = 2500.0 LODDistances(2) = 5000.0
In this case, when the system is [ 0.0 .. 2499.9] from the camera, LOD level 0 will be used. [2500.0 .. 4999.9] from the camera, LOD level 1 will be used. [5000.0 .. INFINITY] from the camera, LOD level 2 will be used.
[edit] LODMethod
Type: ParticleSystemLODMethod
The method of LOD level determination to utilize for this particle system
[edit] Property group 'ParticleSystem'
[edit] SecondsBeforeInactive
Type: float
Number of seconds of emitter not being rendered that need to pass before it no longer gets ticked/ becomes inactive.
[edit] SystemUpdateMode
Type: EParticleSystemUpdateMode
[edit] UpdateTime_FPS
Type: float
UpdateTime_FPS - the frame per second to update at in FixedTime mode
Default value: 60.0
[edit] WarmupTime
Type: float
WarmupTime - the time to warm-up the particle system when first rendered
[edit] Property group 'Thumbnail'
[edit] bUseRealtimeThumbnail
Type: bool
Inidicates the old 'real-time' thumbnail rendering should be used
[edit] ThumbnailWarmup
Type: float
The time to warm-up the system for the thumbnail image
Default value: 1.0
[edit] Internal variables
[edit] bHasPhysics
Type: bool
Modifiers: transient
Set during load time to indicate that physics is used...
[edit] bLit
Type: bool
Boolean to indicate whether the particle system can ignore lights or not
Default value: True
[edit] bRegenerateLODDuplicate
Type: bool
Internal value that tracks the regenerate LOD levels preference. If TRUE, when autoregenerating LOD levels in code, the low level will be a duplicate of the high.
[edit] bShouldResetPeakCounts
Type: bool
EDITOR ONLY: Indicates that Cascade would like to have the PeakActiveParticles count reset
[edit] CurveEdSetup
Type: InterpCurveEdSetup
Modifiers: export
Used for curve editor to remember curve-editing setup.
[edit] EditorLODSetting
Type: int
LOD setting for intepolation (set by Cascade) Range [0..100]
[edit] Emitters
Type: array<ParticleEmitter>
Modifiers: editinline, export
Emitters - internal - the array of emitters in the system
[edit] FloorMesh
Type: string
Default value: "EditorMeshes.AnimTreeEd_PreviewFloor"
[edit] FloorPosition
Type: Object.Vector
[edit] FloorRotation
Type: Object.Rotator
[edit] FloorScale
Type: float
Default value: 1.0
[edit] FloorScale3D
Type: Object.Vector
Default value:
| Member | Value |
|---|---|
| X | 1.0 |
| Y | 1.0 |
| Z | 1.0 |
[edit] PreviewComponent
Type: ParticleSystemComponent
Modifiers: transient
The component used to preview the particle system in Cascade
[edit] ThumbnailAngle
Type: Object.Rotator
The angle to use when rendering the thumbnail image
[edit] ThumbnailDistance
Type: float
The distance to place the system when rendering the thumbnail image
Default value: 200.0
[edit] ThumbnailImage
Type: Texture2D
Internal: The PSys thumbnail image
[edit] ThumbnailImageOutOfDate
Type: bool
Internal: Indicates the PSys thumbnail image is out of date
Default value: True
[edit] UpdateTime_Delta
Type: float
UpdateTime_Delta - internal
Default value: 1.0
