class UMaterialExpressionVectorNoise : public UMaterialExpression
Variables
| Type | Name | Description | |
|---|---|---|---|
   |
uint32: 1 | bTiling | Whether tile the noise pattern, useful for baking to seam-free repeating textures |
   |
TEnumAsByte< enum EVectorNoiseFunction > | NoiseFunction | Noise function, affects performance and look |
  |
FExpressionInput | Position | 2 to 3 dimensional vector |
   |
int32 | Quality | For noise functions where applicable, lower numbers are faster and lower quality, higher numbers are slower and higher quality |
   |
uint32 | TileSize | How many units in each tile (if Tiling is on) For Perlin noise functions, Tile Size must be a multiple of three |
   |
EPositionOrigin | WorldPositionOriginType | Defines the reference space for the Position input. |
