Using Godot. I can't figure out how to bitmask these tiles in order to autotile them. I've examined the templates shown in the Godot Docs Tilemaps tutorial, but none seem appropriate. My own attempts to solve this through trial and error have left me confused and frustrated. The tiles are 32x32 pixels, and I'm fairly sure I need a 3x3 minimal masking layout.

Your tileset is not ideal to use for autotiling, as many common pieces are missing, for example the L shape. I modified the tileset and used 160x160 wide tiles, this is the result:

The blue checkerboard means that the cell is ignored, so it could be either filled or empty.
