The Sign node
When to use it
+1 for positive, -1 for negative, 0 for exactly zero.
On a density field that turns a smooth distance into a hard inside-or-outside flag. Occasionally that is what a mask wants. It is always bad input for the mesher, which needs a slope to find the crossing point in. Give it a sign and the surface snaps to voxel corners.
SmoothStep is the soft version.
