The marker overlays from Day 16 for the highlight marker effect. Recolor them with Color Generator and set the blend mode to Multiply.
How it's built
- Place the overlay, color it with the Color Generator effect, blend mode Multiply.
- In Fusion, draw a polygon mask around the marker and keyframe its X position.
- Open the splines, press S on both points and shape the curve for a smooth stroke.
