Variables

	Name	Description
uint32: 1	bApplyNoiseScale	If true, apply the noise scale to the beam.
uint32: 1	bLowFreq_Enabled	Is low frequency noise enabled.
uint32: 1	bNoiseLock	INTERNAL - Whether the noise points should be locked.
uint32: 1	bNRScaleEmitterTime	If true, the NoiseRangeScale will be grabbed based on the emitter time.
uint32: 1	bOscillate	Whether the noise points should be oscillate.
uint32: 1	bSmooth	Whether the noise movement should be smooth or 'jerky'.
uint32: 1	bTargetNoise	Whether to apply noise to the target point (or end of line in distance mode...) If true, the beam could potentially 'leave' the target...
uint32: 1	bUseNoiseTangents	If true, calculate tangents at each noise point.
int32	Frequency	The frequency of noise points.
int32	Frequency_LowRange	If not 0, then the frequency will select a random value in the range [Frequency_LowRange..Frequency]
float	FrequencyDistance	The distance at which to deposit noise points.
float	NoiseLockRadius	Default target-point information to use if the beam method is endpoint.
float	NoiseLockTime	How long the noise points should be locked - 0.0 indicates forever.
FRawDistributio...	NoiseRange	The noise point ranges.
FRawDistributio...	NoiseRangeScale	A scale factor that will be applied to the noise range.
FRawDistributio...	NoiseScale	The scale factor to apply to noise range.
FRawDistributio...	NoiseSpeed	The speed with which to move each noise point.
FRawDistributio...	NoiseTangentStrength	The strength of noise tangents, if enabled.
float	NoiseTension	The tension to apply to the tessellated noise line.
int32	NoiseTessellation	The amount of tessellation between noise points.
