 # The masters' claimed floors (high-res)

+`resolution: 2K`, one image per master. Each sheet has six tiles in a 3x2 grid on magenta; tiles
+1-5 are used (plain, engraving, cracks, chipped, broken; `HD_FLOORS` in `src/gfx.rs`, weighted

+The first version (`v1/`) had regular slabs with thick grout frames and looked too even; this
+one asks for roughly hewn castle flagstones worn smooth by many feet.

-A texture sheet of six square floor tiles for a dark-fantasy dungeon strategy game, arranged in a grid of 3 columns and 2 rows, the tiles separated by thin flat pure magenta (#FF00FF) gaps, magenta also around the outside. Every tile is seen straight from above (orthographic top-down, no perspective), flat even lighting, no shadows, and fills its square completely. Every tile is one square floor slab made of a few fitted flagstones, with a dark grout line along all four edges, so the tiles fit together in any arrangement. All six tiles use the same stone, colours and style: {floor} The six tiles differ: tile 1 intact and clean; tile 2 with a large carved engraving in the middle; tile 3 with fine hairline cracks; tile 4 with a chipped corner and a few missing stone splinters; tile 5 with a broken flagstone, cracked through, a piece sunk and loose rubble; tile 6 with small engravings and worn edges. Style: hand-painted pixel art, chunky clear shapes, crisp edges, readable at small size. No text, no labels, no numbers.
+A texture sheet of six square floor tiles for a dark-fantasy dungeon strategy game, arranged in a grid of 3 columns and 2 rows, the tiles separated by thin flat pure magenta (#FF00FF) gaps, magenta also around the outside. Every tile is seen straight from above (orthographic top-down, no perspective), flat even lighting, no shadows, and fills its square completely. Every tile is a piece of the floor of an old medieval castle dungeon: irregular, roughly hewn flagstones of clearly different sizes and shapes (some large, some small, uneven outlines, slightly rounded chipped edges), laid with uneven mortar joints of varying width - not a regular grid. Centuries of feet have worn the stones smooth and polished: soft sheen on the walked-on surfaces, rounded worn edges, shallow dips. Along the four edges of every tile runs a mortar joint as thin and irregular as the ones inside, so the tiles fit together in any arrangement without a visible grid. All six tiles use the same stone, colours and style: {floor} The six tiles differ: tile 1 plain worn stones; tile 2 with a carved engraving on one large stone, worn half smooth; tile 3 with hairline cracks; tile 4 with a chipped stone corner and missing splinters; tile 5 with a broken flagstone, cracked through, a piece sunk and loose rubble; tile 6 with a few small worn engravings. Style: hand-painted pixel art, crisp edges, muted natural stone colours, readable at small size. No text, no labels, no numbers.

 ## Processing
 
-`tools/make_floor_tiles.py` crops the slabs, fills magenta inside them (chipped corners, holes)
-with a dark void, brightens if asked, scales and reduces the colours:

-The player's sheet came out too dark (brightened by 1.45); its fourth slab repeats the big skull
-with a chipped corner and is left out. Saffrax' sandstone was too glaring (darkened by 0.82).
