Wilbur , how to scale sea?

[Naima]

Hi , I want to reduce the deepness of my sea, and rise some parts of the sea that shoudl be more light color so more turquoise than violet .. but whenever I apply a scale or wilbur scale or exponential , the whole sea bocomes violet and seems to loose all the low shallow water areas wich instead I wanted to increase, the problem is I do not want to rise the whole sea to not change the coastline and I do not want to change the land height .. so how can I do ?

In the Wilbur shader setup, set manual altitude on and set your desired min and Max altitude value.
