Blend¶
modifier.blend · Combine · Mask-aware
Composites two fields by a mode (normal, add, subtract, multiply, max, min, difference) eased in by opacity.
Purpose¶
Composites two fields into one by a chosen mode, eased in by opacity. Reach for it to layer detail onto a base, add or subtract shapes, or lay one field over another through a mask.
Inputs¶
baseoverlaymask(optional)
Outputs¶
out
Parameters¶
| Parameter | Type | Range | Default | Unit | Description | Field-driven |
|---|---|---|---|---|---|---|
Mode (mode) |
enum | normal, add, subtract, multiply, max, min, difference | normal | How the overlay is combined with the base field. | no | |
Opacity (opacity) |
float | [0, 1] | 1 | no |
Layer contract¶
Honours a mask on its input, applying everywhere the mask is absent.
Behaviour¶
The modes are the usual compositing operations: normal, add, subtract, multiply, max, min, and difference. A mask input confines the composite to part of the terrain, so an overlay lands only where you select.
