Yet another question is that somehow I am finding enormous difficulties to make the tools do what they should , for example the smooth doesn't smooth and instead rises huge blobs of terrain , the rough sometimes lowers some other times rises terrain but doesn't create proper roughtness ...

so inthe regions I rised from sea I susually have a more blobby look how can I do to give the proper rough shape of rest of the territories as well as give the same contnental platform surrounding?
