Import tilesets and paint terrain

Step 1

Prepare the source art

Use a tileset image whose cells line up to the tile size you plan to use in the map. A dense, zero-margin grid is the easiest path for native editing and for engine exports that reconstruct tile coordinates from the grid.

1. Choose a tile size before importing the tileset.
2. Use source art with consistent rows and columns.
3. Import the image as a tileset or import a native .2dt tileset file.

Step 2

Configure terrain rules

Open the autotile or terrain editor for the active tileset when you want rule-driven painting. Assign the tiles that represent corners, edges, fills, diagonals, or sparse variants, then choose the terrain rule from the Autotile tool menu.

• Use the Standard preset for common edge and corner terrain.
• Use the Diagonal preset when diagonal transitions matter.
• Use the Sparse preset for lighter rule sets or partial terrain coverage.

Step 3

Paint and fill terrain

Autotile painting updates neighboring cells according to the chosen rule. Terrain fill is useful when you want a larger region to use a weighted set of tile variants rather than a single repeated tile.

1. Select the active tileset and configured terrain rule.
2. Press A or use the toolbar to select the Autotile tool.
3. Choose a brush size from 1x1 through 5x5.
4. Use Fill Terrain when a region should be filled from a reusable weighted set.
