Curvature¶
modifier.curvature ยท Selectors
Selects convex (ridges, outcrops) or concave (valleys, hollows) ground from the surface curvature.
Purpose¶
Selects convex ground (ridges, outcrops) or concave ground (valleys, hollows) from the surface curvature. Reach for it to catch the crests or the hollows, where neither a height nor a slope band would find them.
Inputs¶

Outputs¶

Parameters¶
| Parameter | Type | Range | Default | Unit | Description | Field-driven |
|---|---|---|---|---|---|---|
Mode (mode) |
enum | convex, concave | convex | Which ground to select: convex (ridges, outcrops) or concave (valleys, hollows). | no | |
Strength (strength) |
float | [0, 8] | 1 | no | ||
Output (output) |
enum | selection, measure | selection | no |
Layer contract¶
Reads and writes the height layer.
Behaviour¶
It measures curvature, not slope, so a plain ramp reads as zero. Set the scale it works at with an upstream Blur.
