Equipment Icon Quality Audit

Generated by scripts/audit-equipment-icon-quality.mjs.

Summary

• Catalog items: 23
• Generated procedural item textures: 23
• Slots: accessory 7, armor 5, weapon 11
• Ranks: common 11, treasure 12
• Texture size: 64px
• Drawing grid: 28 units scaled 2.29x into the texture
• Runtime item icon scene: src/game/scenes/CampScene.ts
• Observed runtime display sizes: 14px, 20px, 21px, 22px, 30px
• Direct item texture render sites found: 5

Main Findings

• Equipment item icons are generated at runtime in BootScene, not stored as individual raster images.
• The 64px textures are drawn from a compact 28-unit source grid, so they are crisp but intentionally simple.
• Battle combat preview mostly uses the high-resolution battle-ui-icons slot frames and item names; per-item textures appear primarily in camp/sortie equipment UI.
• Treasure/common distinction often relies on UI frame color plus a small palette change, not a strong unique silhouette.
• Reused helper silhouettes are the strongest quality risk because several different items collapse to the same shape at 14-22px.

Completed Improvement Passes

• weapon spear/polearm family: green-dragon-glaive, serpent-spear, sky-piercer-halberd, iron-spear, western-cavalry-spear
  • The previous shared spear/polearm silhouettes now use item-specific helper shapes with enough primitive detail for 20px and 30px equipment UI reads.

Next Improvement Target

• Target: armor silhouettes
• Item ids: oath-robe, reinforced-lamellar, cloth-armor, lamellar-armor, rebel-vest
• Reason: Armor and robes are readable but still depend on simple triangular torsos and small color accents; this is now the largest remaining shared-equipment silhouette group.

Follow-Up Targets

• accessory charms and tokens: bravery-token, mountain-guide-scroll, peach-charm, war-manual, wind-quiver, grain-pouch, yellow-scarf-charm
  • Accessories are the smallest UI read and several use compact badge-like shapes.

Recommended Next Batch Definition

• Scope: improve armor silhouettes while keeping item-${itemId} texture keys stable.
• Item ids: oath-robe, reinforced-lamellar, cloth-armor, lamellar-armor, rebel-vest
• Success criteria: Each armor item should keep its slot identity while gaining a distinct outer silhouette and material cue at 20px and 30px.
• Keep the existing 64px texture size unless a UI-wide equipment icon pass is planned.
• Add before/after contact sheets and verify the sortie equipment list and equipment swap panel in a desktop browser.
