Variables

  Type Name Description
Public variable uint32: 1 bApplyParticleRotationAsSpin If true, apply 'sprite' particle rotation about the orientation axis (direction mesh is pointing).
Public variable uint32: 1 bApplyPreRotation 'orientation' items...
Public variable uint32: 1 bFaceCameraDirectionRatherThanPosition If true, all camera facing options will point the mesh against the camera's view direction rather than pointing at the cameras location.
Public variable uint32: 1 bUseCameraFacing If true, then use the camera facing options supplied. Trumps all other settings.
Public variable uint32: 1 bUseMeshLockedAxis If true, then use the locked axis setting supplied.
Public variable bool bUseStaticMeshLODs  
Public variable uint8 CameraFacingOption The EMeshCameraFacingOption setting to use if bUseCameraFacing is true.
Public variable const FParticleMeshEmitterInstance * EmitterInstance  
Public variable int32 LastCalculatedMeshLOD  
Public variable int32 LastFramePreRendered  
Public variable float LODSizeScale  
Public variable TArray< FMaterialRenderProxy *, TInlineAllocator< 2 > > MeshMaterials  
Public variable uint32 MeshTypeDataOffset Offset to FMeshTypeDataPayload
Public variable FDynamicMeshEmitterReplayData Source The frame source data for this particle system.
