Variables

Type	Name	Description
TEnumAsByte< EParticleAxisLock >	AxisLockOption	The axis to lock the mesh on.
uint8: 1	bApplyParticleRotationAsSpin	If true, apply 'sprite' particle rotation about the orientation axis (direction mesh is pointing).
uint8: 1	bCameraFacing	If true, then point the X-axis of the mesh towards the camera.
uint8: 1	bCollisionsConsiderPartilceSize	If true, all collisions for mesh particle on this emitter will take the particle size into account.
uint8: 1	bEnableMotionBlur
uint8: 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.
uint8: 1	bOverrideDefaultMotionBlurSettings
uint8: 1	bOverrideMaterial	If true, use the emitter material when rendering rather than the one applied to the static mesh model.
uint8: 1	bUseStaticMeshLODs	Use the static mesh's LOD setup and switch LODs based on largest particle's screen size
TEnumAsByte< enum EMeshCameraFacingOptions >	CameraFacingOption	The camera facing option to use: All camera facing options without locked axis assume X-axis will be facing the camera.
uint8: 1	CastShadows	If true, has the meshes cast shadows
uint8: 1	DoCollisions	UNUSED (the collision module dictates doing collisions)
float	LODSizeScale	Use the static mesh's LOD setup and switch LODs based on largest particle's screen size
TObjectPtr< UStaticMesh >	Mesh	The static mesh to render at the particle positions
TEnumAsByte< enum EMeshScreenAlignment >	MeshAlignment	The alignment to use on the meshes emitted.
FRandomStream	RandomStream	Random stream for the initial rotation distribution
FRawDistributionVector	RollPitchYawRange	The 'pre' rotation pitch (in degrees) to apply to the static mesh used.
