This is a quick overview of the Deformer class which is the main point of interaction with the library. Drop the Deformer script on your GameObject and it is now a dynamic terrain object. All “Now” functions are to conveniently set terrain changes and commit them to the terrain in one step. For compound deformations (for example: Add and Smooth in one frame) use the non-“Now” versions of each function and then call “SetHeights” and/or “SetAlphas” once finished. Please see the Deformer’s detailed class documentation for more in depth information.
