Get an interpolated normal at a given location.

Gets the gradient of the terrain at point (x,y).

Returns an array of all supported detail layer indices in the area.

Get the tree instance at the specified index. It is used as a faster version of treeInstances[index] as this function doesn't create the entire tree instances array.

The index of the tree instance.

Reloads all the values of the available prototypes (ie, detail mesh assets) in the TerrainData Object.

Assign all splat values in the given map area.

Sets the detail layer density map.

Set the resolution of the detail map.

Specifies the number of pixels in the detail resolution map. A larger detailResolution, leads to more accurate detail object painting. Specifies the size in pixels of each individually rendered detail patch. A larger number reduces draw calls, but might increase triangle count since detail patches are culled on a per batch basis. A recommended value is 16. If you use a very large detail object distance and your grass is very sparse, it makes sense to increase the value.

Set an array of heightmap samples.

First x index of heightmap samples to set. First y index of heightmap samples to set. Array of heightmap samples to set (values range from 0 to 1, array indexed as [y,x]).
