Create a Size Gradient Pattern

Use a Size gradient when opening size should change across the Canvas while the base Layout remains recognizable. This guide uses one Point control and Clamp mapping.

Before You Start

Create a simple Grid with one base Shape. Confirm that spacing and Min Bridge are acceptable before enabling Gradient. This gives you a stable result to compare against.

Steps

Open Gradient and turn on Enable Gradient.
Select Size under Gradient Dimension.
Select Point under Controls.
Choose Add Point, then place or select the point on the Canvas.
Adjust Influence Radius until the control covers the intended region.
Keep Mapping Mode on Clamp for the first result.
Increase Center Scale to enlarge openings near the control, or reduce it to make them smaller.
Adjust the curve only after the center and edge sizes are understandable.

Check the Result

The screenshot shows a Point control at approximately 28% X and 50% Y, an Influence Radius of 0.75, and a Center Scale of 2.25. Openings are largest near the point and become smaller across the influence field.

The exact Holes, Open Rate, and Min Bridge values depend on the base Layout and radius. Watch all three after changing the scale.

Use a Line Instead

Choose Line when size should change primarily in one direction. Set the line position, direction, influence range, center effect, and curve. Repeat or Mirror can extend the behavior, but they also make local bridge checks more important.

Troubleshooting

No visible change: Confirm Enable Gradient is on, Size is active, and the selected control is enabled.
Openings overlap near the center: Reduce Center Scale, reduce the base radius, or increase Layout spacing.
The transition feels abrupt: Increase Influence Radius or choose a smoother curve.
The wrong area changes: Move the Point or Line rather than changing Canvas dimensions.
