Create a tileset

There are two ways to get a tileset into a pack: bring in an image you already have, or draw your own from scratch. Draw a Blank Tileset is the draw-your-own path - it mints a blank grid you fill cell by cell, then paint maps with, exactly like an imported tileset.

Creating a tileset is free - it’s just drawing into a grid.

Tileset, not terrain

A tileset is a collection you pick from tile by tile - grass, water, a fence, a 2x3 tree - the kind of sheet most engines and most people mean by “tileset.” That is what this page is about.

A terrain is a different thing: one autotiling material whose edges and corners resolve themselves as you paint. You either generate one from two tiles or draw one piece by piece - but either way you paint regions with it, you don’t pick cases by hand. If you want a smart brush that fixes its own edges, you want a terrain, not a tileset.

Creating one

Pick Tile → Draw a Blank Tileset…, or the matching button in the Tile Shelf’s empty state. The dialog asks for:

Tileset Name - names the tileset’s tab in the shelf.
Grid Size (cells) - how many columns and rows of cells.
Tile Size - the pixel size of each cell. To paint a map with the tileset, this must match the map’s tile size.

A summary line shows the resulting sheet dimensions (columns x cellSize by rows x cellSize) so you can see it stays within the 4096-pixel-per-side ceiling before you commit. Click Create Tileset and a blank grid appears in the shelf as a new tileset tab, opened in Edit mode.

Drawing your tiles

A new tileset opens in Edit mode, with every cell of the grid shown as an empty target:

Click an empty cell to start a tile there - it becomes the active asset and opens for drawing.
Draw with any tool, exactly as you would on a normal canvas.
Click the next cell to draw the next tile. Each cell you open becomes the active asset automatically, so there’s no “done” step between tiles.
Click a drawn cell again to revise it later.

Turn on Show cell grid in the panel header to outline the cells that already hold a tile, so you can see what you’ve filled in.

Painting with it

When the tileset is ready to use, flip the panel header’s Stamp / Edit toggle to Stamp:

Click a tile to arm it, then paint it onto a map.
Drag across the atlas to grab a multi-tile block
- a tree or a building stamps in one move.

This is identical to how an imported tileset behaves - see Stamp or Edit a tileset for the full toggle reference. Flip back to Edit any time to keep drawing.

Good to know

A hand-drawn tileset is a single sheet asset, so it fits the free plan’s per-pack asset limit the same way an imported one does.
It exports, syncs, and travels inside .hexc pack files like any other asset.
Pop it out, rename it, or delete it from the same panel header actions an imported tileset carries.
