Variables
| Type | Name | Description | |
|---|---|---|---|
   |
float | Amplitude | The magnitude or strength of the variations introduced by procedural noise. Adjusting this parameter can control the intensity or impact of procedural noise on textures or effects. |
   |
float | Frequency | Determines how quickly or slowly the patterns change within the generated noise. |
   |
float | Lacunarity | Number that determines how much detail is added to or removed from the noise signal (adjusts frequency) |
    |
TEnumAsByte< ENoiseType > | NoiseType | The type of the noise function. |
   |
int32 | Octaves | The number of levels of details that you want from the noise signal. |
   |
FTG_Texture | Output | The generated noise texture. |
   |
float | Persistence | Number that determines how much each octave contributes to the overall shape of the noise signal (adjusts amplitude) |
   |
int32 | Seed | A value used to initialize or "seed" a random number generator when generating procedural noise. Changing the noise seed produces different patterns or variations in the generated noise. |
