Makes near-uniform edge pixels transparent. Raise the tolerance if a halo survives; lower it if the artwork loses its own edges.
The ceiling on the flatten step. Each colour that survives is a thread change on the machine. Press ↻ beside the switch to re-run.
The pixel grid the flatten and mapping passes run on — not the stitched size. Lower is faster and coarser; the shorter side is what counts.
The colour the design will be sewn onto. It sets the ground in both previews and is remembered between sessions — nothing about the file changes. White and very light artwork vanishes against the checkerboard.
Shared with the Preprocessing preview, so the design keeps the same ground as you move between them.
