Parameters
| Name | Type | Description |
|---|---|---|
| Rotation Angle | Float | No description |
| Asymmetry Ratio | Float | No description |
| Center | Vec2Float | Reference center within the heightmap. |
| Central Peak Extent | Float | No description |
| Central Peak Height | Float | No description |
| Activate | Bool | Enables or disables the built-in drainage noise. If an external noise input is provided, it overrides this default noise. |
| Spatial Frequency | Float | Base spatial frequencies in the X and Y directions. |
| Amplitude | Float | Noise amplitude. |
| Type | Enumeration | Noise type. |
| Seed | Random seed number | Random seed number. The random seed is an offset to the randomized process. A different seed will produce a new result. |
| Smoothness | Float | Controls the resulting smoothness of the fractal layering process. |
| Elevation Offset | Float | No description |
| Inner Basin Depth | Float | No description |
| Inner Basin Falloff | Float | No description |
| Rim Falloff | Float | No description |
| Rim Width | Float | No description |
| Rim Height | Float | No description |
| Terrace Count | Integer | No description |
| Gain | Float | Mid-centered gain transformation applied to the elevation values. This is a non-linear recurve operator centered around the mid elevation (typically 0.5). Increasing the gain pushes values toward the minimum and maximum elevations, creating flatter low/high regions with a steeper transition around the midpoint. |
| Gamma | Float | Standard gamma correction applied to the elevation values. This is a monotonic power-law remapping that shifts emphasis toward low or high elevations, making the overall shape sharper or bulkier without changing its ordering. |
| Invert Output | Bool | Inverts the output values after processing, flipping low and high values across the midrange. |
| Remap Range | Value range | Linearly remaps the output values to a specified target range (default is [0, 1]). |
| Saturation Range | Value range | Modifies the amplitude of elevations by first clamping them to a given interval and then scaling them so that the restricted interval matches the original input range. This enhances contrast in elevation variations while maintaining overall structure. |
| Smoothing Radius | Float | Defines the radius for post-processing smoothing, determining the size of the neighborhood used to average local values and reduce high-frequency detail. A radius of 0 disables smoothing. |
| Crater Radius | Float | Crater radius. |
| Terrace Sharpness | Float | No description |
| Terrace Extent | Float | No description |
| Terrace Persistence | Float | No description |
