bHasPhysics Source code

Set during load time to indicate that physics is used...

bLit Source code

Boolean to indicate whether the particle system can ignore lights or not

bRegenerateLODDuplicate Source code

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.

bShouldResetPeakCounts Source code

EDITOR ONLY: Indicates that Cascade would like to have the PeakActiveParticles count reset

CurveEdSetup Source code

Used for curve editor to remember curve-editing setup.

EditorLODSetting Source code

LOD setting for intepolation (set by Cascade) Range [0..100]

Emitters Source code

Emitters - internal - the array of emitters in the system

FloorMesh Source code

FloorPosition Source code

FloorRotation Source code

FloorScale Source code

FloorScale3D Source code

PreviewComponent Source code

The component used to preview the particle system in Cascade

ThumbnailAngle Source code

The angle to use when rendering the thumbnail image

ThumbnailDistance Source code

The distance to place the system when rendering the thumbnail image

ThumbnailImage Source code

Internal: The PSys thumbnail image

ThumbnailImageOutOfDate Source code

Internal: Indicates the PSys thumbnail image is out of date

UpdateTime_Delta Source code

UpdateTime_Delta - internal

Bounds

bUseFixedRelativeBoundingBox Source code

Whether to use the fixed relative bounding box or calculate it every frame.

FixedRelativeBoundingBox Source code

Fixed relative bounding box for particle system.

LOD

LODDistanceCheckTime Source code

How often (in seconds) the system should perform the LOD distance check.

LODDistances Source code

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.

LODMethod Source code

The method of LOD level determination to utilize for this particle system

ParticleSystem

SecondsBeforeInactive Source code

Number of seconds of emitter not being rendered that need to pass before it no longer gets ticked/ becomes inactive.

SystemUpdateMode Source code

FixedTime - update via a fixed time step

UpdateTime_FPS Source code

UpdateTime_FPS - the frame per second to update at in FixedTime mode

WarmupTime Source code

WarmupTime - the time to warm-up the particle system when first rendered

Thumbnail

bUseRealtimeThumbnail Source code

Inidicates the old 'real-time' thumbnail rendering should be used

ThumbnailWarmup Source code

The time to warm-up the system for the thumbnail image

EParticleSystemUpdateMode Source code

ParticleSystemUpdateMode Enumeration indicating the method by which the system should be updated

ParticleSystemLODMethod Source code

ParticleSystemLODMethod Enumeration indicating the method by which the system should perform LOD determination

GetCurrentLODMethod Source code

Return the currently set LOD method

GetLODDistance Source code

Return the distance for the given LOD level

GetLODLevelCount Source code

Return the number of LOD levels for this particle system

SetCurrentLODMethod Source code

Set the LOD method

SetLODDistance Source code

Set the distance for the given LOD index
