# Furniture materials (2026-11-07)

Textures for the furniture boxes of `src/props.rs` (`Mat`, `mc`): every box of a material gets the
texture on all sides, tinted by the box's own colour, so the furniture keeps its colours and gains
detail (book spines with titles, a spellbook page with script, straw dummies, wood grain, ...).

`fal-ai/flux-2-pro`, `image_size: square_hd`, `seed: 4400`; the material's sentence followed by:

```text
Square texture seen straight on, flat even lighting, no shadows, no vignette, no border, no text unless asked. Hand-painted pixel art style for a dark-fantasy dungeon strategy game: chunky clear shapes, crisp edges, readable at small size. Fills the whole image.
```

## wood

```text
Light weathered wooden planks running vertically with clear wood grain, knots and a few nail heads, in light neutral beige tones.
```

## stone

```text
A rough block of light grey stone with chisel marks, small pits and a few fine cracks, in light neutral grey tones.
```

## iron

```text
Light grey forged iron with hammer dents, scratches and a few rivets near the edges, in light neutral grey tones.
```

## cloth

```text
Woven fabric with a visible coarse weave, soft folds and a simple embroidered border near the edges, in light neutral off-white tones.
```

## straw

```text
Bundled straw and sackcloth: coarse burlap with straw sticking out, stitched seams, in light neutral beige tones.
```

## fur

```text
Thick shaggy animal fur with tufts and strands, in light neutral beige-grey tones.
```

## book

```text
The spine of one old leather-bound book standing upright, filling the whole image: two raised bands near the top and the bottom, a gilded frame and a short line of golden title letters in the middle, worn leather, in light neutral tones.
```

## paper

```text
An open page of an old spellbook filling the whole image: yellowed parchment with many lines of dark handwritten script, a small drawn magic circle and a red initial letter, in light neutral tones.
```

## crystal

```text
A cut gemstone surface seen close: many sharp triangular and kite-shaped facets with bright edges and darker faces, a few internal glints, in light neutral grey tones.
```

The soul core's heart (its lobes) and the buildings use the materials too: `props::auto_cube`
picks one for every box of the buildings by its colour and shape.

## Processing

`tools/make_material.py` crops (stone and the book lay on white), turns the picture into grey
detail with a mean brightness of 0.8 (the page keeps its colours) and scales to 64x64 (high-res)
and 16x16 (pixel art):

```bash
