Tileset Base Generator
Build the 15-piece base shape for a top-down tileset from scratch. Pick a tile size, shape the edges and colors, and export a pixel-perfect PNG you can drop straight into a game or hand to an AI as a reference.

Output
One sheet, every connection
Top-down terrain tilesets share the same 4x4 layout. Sixteen tiles cover every way the ground can meet its edge at the four corners, and one tile is empty, so you get 15 usable pieces. Lay them next to each other and the terrain flows seamlessly in any direction.
The generator draws that exact structure. Edges bleed to the tile border so neighbors connect, rounding and roughness only appear where the shape faces empty space, and diagonal tiles bridge through the center instead of pinching at a point.
Turn the base into a finished tileset
The base sets the resolution and the silhouette. Feed it to SpriteCook and the AI fills in real texture at the same size and layout, so the tiles still connect.
