CucoloriParameters
Frame Layer
Close shadow layer with blinds, windows, and abstract patterns.
The close shadow. Geometric patterns that simulate objects between the light source and the subject: venetian blinds, window mullions, or abstract noise. These tend to be harder-edged and more structured than the gobo layer.
The frame layer supports projective perspective - lines stay straight but converge toward a vanishing point, just like real shadows cast from a nearby window.
| Parameter | Type | Default | Description |
|---|---|---|---|
| Enable Frame | Toggle | Off | Turns the frame layer on or off. |
| Type | Choice3 types | Blinds | Pattern shape. Each type has its own sub-controls. |
| Scale | Float0.1 - 5.0 | 1.0 | Pattern zoom. |
| Blur | Float0% - 100% | 10% | Edge softness. More blur simulates a more distant or diffuse light source. |
| Offset X | Float-2.0 - 2.0 | 0.0 | Horizontal position. For blinds, also tilts the slat angle slightly. |
| Offset Y | Float-2.0 - 2.0 | 0.0 | Vertical position. |
| Rotation | Float-180 - 180 | 0 | Rotates the entire pattern. Also changes the drift direction. |
| Density | Float0% - 100% | 50% | Blinds: shadow vs gap ratio. Window: bar thickness. Abstract: threshold. |
| Perspective | Float-1.0 - 1.0 | 0.0 | Projective warp. Slats and bars converge toward a vanishing point. Negative values reverse the convergence direction. |
Pattern Types
Blinds
Horizontal bars with adjustable slat count and width. The workhorse for interior shadow looks.
| Parameter | Type | Default | Description |
|---|---|---|---|
| Slat Count | Integer1 - 30 | 8 | Number of slats. |
| Slat Width | Float0% - 100% | 50% | How wide each slat is relative to the gap. |
Window
Rectangular grid that simulates a window casting shadows through its mullions.
| Parameter | Type | Default | Description |
|---|---|---|---|
| Bar Count | Integer1 - 12 | 3 | Grid divisions per axis. |
| Window Aspect | Float0.25 - 4.0 | 1.78 | Width-to-height ratio of the panes. |
Abstract
Procedural noise pattern. Good for organic, non-geometric shadow shapes that don't reference a specific object.
| Parameter | Type | Default | Description |
|---|---|---|---|
| Seed | Integer0 - 9999 | 42 | Random variation. Different seeds produce different patterns. |
Tips
- Perspective at 0.4 - 0.7 with Blinds gives that classic film noir shadow. Push it higher for more extreme convergence.
- Layer Frame (Window) with Gobo (any tree texture) for the full "light through a window with trees outside" setup.
- Abstract patterns work well at low Density (20 - 40%) for subtle, non-specific shadow texture.
- Rotate Blinds 90 degrees for vertical bars.
