Overview

The clip in the header shows Map Builder in use — capturing tiles and painting a layout with the brush.

  • Open it from the Panels menu, the tools panel toggle, or press T.
  • Click a tile in the grid to select it for the Brush tool.
  • Use Add tile after selecting a region on the canvas to capture new art into the library.

What you see in the panel

  • Category filter — show all tiles or focus on one category.
  • Columns — adjust how many tiles appear per row in the grid.
  • Tile grid — thumbnails for every tile on the active layer; drag to reorder.
  • Lock to current layer — pin the panel to one layer's tile library. Switch to another layer and stamp those tiles with the brush — useful when tileset art and painted layout live on separate layers.

Each layer has its own tile library. Switch layers to edit a different set, or lock the panel to keep one layer's tiles available while you paint on any other layer.

For workflows — blocking levels, building tilesets incrementally, syncing art changes across a map, and exporting to your game engine — see Build Maps Quickly.
