The Subtract node
When to use it
A minus B. Arithmetic, not a boolean cut.
To carve one shape out of another, use the Subtraction node. It computes max(A, -B) and leaves you something that is still a distance field. Plain subtraction does not.
Where this one earns its place is building expressions. noise * amplitude - z is the standard height-based terrain field, and it is exactly what both erosion nodes expect to be handed.
