These sliders are everything: The Ultimate Guide to Easy Paint Tool SAI
Size: Base brush diameter. Turn on "Size" checkbox to link to pen pressure (light press = thin line). Min Size: How small the line gets at lightest pressure (e.g., 10%). Density: Opacity of the stroke. Lower density = more transparent. Min Density: Lowest opacity at lightest pressure. Blending: How much the brush picks up existing color (0 = opaque, 100 = behaves like watercolor mixing). Persistence: How much the brush "drags" the color behind it (creates a trail effect). Hard/Soft Edge: Slider from hard (aliased) to soft (feathered).
Pro tip for lineart: Set Pen → Size: on, Min Size: 0%, Density: 100%, Blending: 0, Hard edge: 100. This gives you crisp manga-style lines with perfect tapers.
2.3 Creating & Saving Custom Brushes
Adjust any brush parameters. Click the "Save Brush" icon (diskette) next to the tool name. Name your brush (e.g., "Inking Smooth"). It appears in the dropdown menu. You can delete or reorder them.
