Variables
| Type | 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. |
 |
FRawDistributionVector | NoiseRange | The noise point ranges. |
 |
FRawDistributionFloat | NoiseRangeScale | A scale factor that will be applied to the noise range. |
 |
FRawDistributionFloat | NoiseScale | The scale factor to apply to noise range. |
 |
FRawDistributionVector | NoiseSpeed | The speed with which to move each noise point. |
 |
FRawDistributionFloat | 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. |
