Basalt Tileset

Basalt Tileset is a set of 58 tiles drawn in the low-poly style, where the silhouette is an angular polygon and the face is split into flat triangles. 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.

Four triangles meet off-centre and each carries its own flat tone, which is exactly how a faceted mesh shades. There are no curves anywhere in the kit and no gradient on any facet.

Inside that style this is the Basalt reading of it: a dark interface on a ash grey palette with magma orange accents, built around a single bordered frame, square-cornered buttons at 120x44, banded bars divided into 7 segments, and solid icons on a 24px 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 Basalt family, which means this kit and the Basalt panel kit line up without either being resized. A good fit for low-poly games.
