Sumi Tileset

Sumi Tileset is a set of 58 tiles drawn in the cel-shaded style, where a thick ink outline wraps two flat tones split by a hard diagonal terminator. It contains a 47-mask autotile set, ground and wall variations, edge and corner pieces, grid-aligned props and an assembled sheet.

A tileset is only a tileset if the tiles actually connect. Most free sets are a folder of squares that look related and line up almost everywhere, and the almost is what costs an afternoon: one edge mask is off by a pixel and the seam shows on every wall in the level.

The shadow is a single hard-edged shape with no falloff — the defining property of cel shading, and the thing a gradient can never imitate. The outline uses the darkest tone in the palette rather than the border tone, or it reads as a thick grey frame instead of ink.

Inside that style this is the Sumi reading of it: a dark interface on a charcoal wash palette with seal red accents, built around two concentric frames, tab-shaped buttons at 120x48, glossy bars divided into 9 segments, and outlined icons on a 32px grid. Those measurements are why two families can share an art style without being interchangeable: the style decides how an edge is drawn, the numbers decide what the interface is for.

The autotile masks are generated from the same edge geometry rather than drawn one at a time, so a tile and its neighbour share the exact border by construction rather than by care. Ground variations are drawn to be interchangeable at any position, which is what stops a large floor reading as a repeating pattern.

Every sprite ships as an editable SVG and as transparent PNG at 1x, 2x and 4x, so you can drop the PNGs straight into an engine or open the vector and change a colour. Built to the same measurements as the rest of the Sumi family, which means this kit and the Sumi panel kit line up without either being resized. A good fit for cel-shaded and toon-rendered games.
