Directional Blur¶
modifier.directional_blur · Filters · Mask-aware
Smooths the height layer along or across a guide direction, steered by the slope or a flow field.
Purpose¶
Smooths along a direction instead of evenly, guided by the slope or a flow field. Reach for it to comb valleys down their fall line, or to soften a cross-profile while keeping the crest crisp.
Inputs¶
inguide(optional)mask(optional)
Outputs¶

Parameters¶
| Parameter | Type | Range | Default | Unit | Description | Field-driven |
|---|---|---|---|---|---|---|
Radius (radius) |
float | [0, 100000] | 8 | m | no | |
Guide (guide) |
enum | slope, flow | slope | no | ||
Direction (direction) |
enum | along, across | along | Whether smoothing runs along the guide direction or across it. | no |
Layer contract¶
Honours a mask on its input, applying everywhere the mask is absent.
Behaviour¶
The optional guide input steers the direction; with none, it follows the terrain's own slope. Along the guide it combs and smears downslope; across it softens the cross-profile while leaving the guide crest sharp.
