Aspect¶
modifier.aspect · Selectors
Selects slopes facing a compass direction: high where the terrain faces the direction, softening over the falloff.
Purpose¶
Selects slopes that face a compass direction, high where the terrain looks toward it and softening away from it. Reach for it for sun-facing or wind-facing effects: poleward snow, directional weathering.

Parameters¶
| Parameter | Type | Range | Default | Unit | Description | Field-driven |
|---|---|---|---|---|---|---|
Direction (direction) |
float | [0, 360] | 0 | ° | Which way the bands run, in degrees. The crests lie across this direction. | no |
Falloff (falloff) |
float | [1, 180] | 90 | ° | no | |
Slope Weight (slope_weight) |
float | [0, 1] | 1 | no | ||
Output (output) |
enum | selection, measure | selection | no |
Layer contract¶
Reads and writes the height layer.
Behaviour¶
Being a gradient measure, it amplifies sharp input such as thin ridges, so scale it with an upstream Blur. A slope weight suppresses the flats, where facing is meaningless.
