NoiseMask
The horizontal noise mask for the prefab placement position
Type information:
(Nullable) Defines a noise mask that uses fractal simplex noise to control placement density within a configurable threshold range

| Persistence | Number defaults to: 0.6 | The cumulative gain multiplier for each noise octave | |||||||||
| Density | (Nullable)
FloatRange
| Threshold range for the mask. Noise values outside the range result in the prefab position being occluded |

OffsetY
The vertical offset for the prefab placement position
Type information: Integer defaults to: 0
Rotations
The rotation directions that the prefab can be randomly placed in

PointGrid
The point grid for the prefab
Type information:
(Nullable) Defines a point grid that distributes placement positions across the world using a seeded cell-based layout with configurable scale, jitter, and density
PointGrid with the following properties:
