What are Intersect underlying, Intersection zone, shift and min shift?

And how do you use them?Am I right if I think that I should use those if I'm trying to put a soft layer (I mean, like deep snow) on a very hard and detailed terrain?



I was always wondering about the same question. I'm using these features, and I have a rough idea about what they do, but it's not 100% clear to me nevertheless.

Intersection zone: the minimum (or average?) size of the area on which either favour depressions, rises or intersect underlying will be applied to
Shift: height in meters by which the top layer will be lifted (or depressed) compared to the lower layer.
Min Shift: I'm not clear on this one

Furthermore, I think that favour depressions, rises and intersect underlying are essentially the same function, but depressions limits its effect to depressions, and rises limits it to rises, whereas intersect underlying doesn't differentiate between rises and depressions.

The closer the values of shift and min shift are, the more contrast is on the distribution ... as a small addition.
