For the game to use them you must simply respect a few rules:
- they must be 64x64 or 64x128 tiles
- they must be saved as PNG files
- you must place them in folder #LIGHT_BLUE#%s#WHITE#
Once you have done so, simply restart the game and the tiles will be listed at the bottom of the list.]]):format(fs.getRealPath("/data/gfx/custom-tiles/")),500)
