Linear Fill Modifier

Converts the fill color of a shape into line density hairlines for fast, clean scoring. Darker areas produce tighter spacing, lighter areas produce wider spacing. The first shape is the mask. Line density is set by LPI and brightness. Angle comes from the alpha.

What it does

• Generates parallel hairline strokes and clips them to the input shape

• Dark areas get tighter spacing and more lines

• Angle is driven by alpha from 0 to 180 degrees

• Optional outline of the original mask stroke

Parameters

• lpi: lines per inch used for black density

• invert: flips dark and light mapping (for dark material)

• fallbackColor: used only if the input has no fill color

• keepMaskStroke: true to add the mask outline as a stroke

Notes

• Output is strokes only and uses hairline for fast scoring

• Angle from alpha lets you encode orientation in the color picker if you want per part control
