The Terrain Filter operator can be used to apply a filter to a terrain grid.
Grid names: terrain grids with matching names will be affected by the specified filter.
Mode: the filter mode to apply to applicable terrain grids.
Applies a 2D gaussian blur filter to the cells of affected terrain grids.
Clamps the height values of cells in affected terrain grids.
Normalized: when enabled, the clamp min/max percentage values are relative to the min/max height values of affected grids. When disabled, clamp min/max values are in world-space units.
Preserve height: when enabled, the resulting height values will be adjusted to match the original range of pre-clamped height values.
Min/Max: the min/max range of the clamp filter.
Applies a denoise filter to cells in affected terrain grids, smoothing out small noise/details.
Block size: smaller values smooth out smaller noise, larger values smooth out larger noise.
Threshold: noise with a frequency below this threshold will be smoothed.
Displaces the height values of affected grids by the values in the specified color channel.
Color channel: the grid color channel from which to derive the displacement values.
Channel: controls which color channel (or an average of all of them) to get displacement values from.
Amount: the amount, in world-space units, to displace affected terrain grids.
Inverts all height values in affected terrain grids.
Multiplies all height values in affected terrain grids by the specified amount.
Offsets all height values in affected terrain grids by the specified amount, in world-space units.
Reshapes affected terrain grids by using a curve to remap height values.
Reshape curve: height values in affected terrain grids will be re-mapped by their corresponding height value along this curve.
Normalize: the resulting height value range will be adjusted to match the original height value range.
Applies a 2D sharpening filter to cells in affected terrain grids.
Mode: the sharpening algorithm to use.
Amount: the amount of sharpening to apply.
