What is generally the best and/or most useful heightmapping tool?

Use Texture>>Shader Setup, click on the Altitude tab to show the Altitude page. Check the "Absolute Coloring" checkbox, then set your min and max values for land and sea.

That doesn't fix anything, I use the bump map shader most of the time anyway. When trying to make a mountain range and I use something like Set Value, Offset (Add), or Fill Mound, regardless of the input it will rescale the rest of the map in order to raise the land by a seemingly unrelated value, if that explanation makes any sense. It's frustrating because no matter the value I put in, I'm left in the dark as to how much the land has been raised or lowered by, no matter what the operation is.
