| Name | Type | Default value | Description |
| hInputHF | hvar | N/A | A handle to the heightfield to be inflated. |
| hDesignMap | hvar | N/A | A handle to the design map. |
| nLevels | int | 1 | The number of levels of inflation. Each level doubles the dimensions of the map. |
| FractalWeight | float | 100 | A weighting for the strength of the fractal noise to be applied during inflation (see comment below). |

| hOutputHF | hmap | A handle to the inflated heightfield. |
This filter has no options.
The fractal weighting at each point in the heightfield is controlled by the 'frac' parameter of each pixel in the design map. The FractalWeight parameter in this filter may be used to increase or decrease the overall fractal noise used for the inflation levels across the whole map. Typically, for late-stage inflation near the final resolution of the heightfield, the fractal weighting is decreased to 50.
