Does anyone know what the current limits are on remodelling (terraforming) purchased land (specifically mainland), or of a document/location where I can find out (a note or guide for instance). I've noticed a lot of new land on the mainland that has become available for sale has been formed into a series of step like structures (to make building easier I guess..but totally unnatural) precisely the size of the individual plots. Does this mean the land can no longer be modelled back to its original 'natural' form. I'm looking to buy several adjoining plots and want to return it to this 'natural' form ?
Maybe I ought to add that by 'limits' I mean changing the height or depth and the application of textures.
