Name Type Remarks Include Path Unreal Specifiers
bApplyParticleRotationAsSpin uint32 If true, apply 'sprite' particle rotation about the orientation axis (direction mesh is pointing). ParticleHelper.h  
bApplyPreRotation uint32 'orientation' items... ParticleHelper.h  
bFaceCameraDirectionRatherThanPosition uint32 If true, all camera facing options will point the mesh against the camera's view direction rather than pointing at the cameras location. ParticleHelper.h  
bUseCameraFacing uint32 If true, then use the camera facing options supplied. Trumps all other settings. ParticleHelper.h  
bUseMeshLockedAxis uint32 If true, then use the locked axis setting supplied. ParticleHelper.h  
bUseStaticMeshLODs bool   ParticleHelper.h  
CameraFacingOption uint8 The EMeshCameraFacingOption setting to use if bUseCameraFacing is true. ParticleHelper.h
