The Terrain Resample operator can be used to resample a terrain grid.
Grid names: terrain grids with matching names will be resampled.
Mode: “Simple” mode will resample all affected grids the same way. “By distance to object” mode will resample grids based on their distance to a specified object.
“By distance to object” mode allows you to do things like generate higher-resolution grids closer to a camera, and lower-resolution grids further away.
Relative +/-: when selected, resampled grid resolutions will be increased or decreased, by the relative power. For example, a grid resolution of 256 (2^8) will be changed to 512 (2^9) if the value is set to “1”, 1024 (2^10) if the value is set to “2”, or 32 (2^5) if the value is set to “-3”.
Absolute: when selected, resampled grid resolutions will be set to the specified value.
Object: the object to which distance measurements will be calculated.
Close distance: the minimum distance threshold, below which all distances will be considered close.
Far distance: the maximum distance threshold, beyond which all distances will be considered far.
Close resolution: affected terrain grids considered “close” will be resampled to this resolution.
Far resolution: affected terrain grids considered “far” will be resampled to this resolution.
Affected terrain grids with a distance value between the close/far thresholds will have their resolutions resampled to an interpolated power between the close/far resolution values. For example, if the close threshold is 0 and the far threshold is 100, and the close resolution is 128 (2^7) and the far resolution is 512 (2^9) and the distance an affected terrain is to the specified distance object is 50 scene units, the affected terrain will be resampled to a resolution of 256 (2^8).
