 ### Character and prop textures
 
-- [-] Audit NPC skin, cloth, pants, hair and gear albedo/normal/AO maps in portraits;
-      refine fabric weave, skin variation and fixed detail materials. (256² maps are built and
-      all eight characters rebuilt; the large fabric/UV pattern and skin/fixed-detail audit are
-      still open.)
+- [x] Audit NPC skin, cloth, pants, hair and gear albedo/normal/AO maps in portraits;
+      refine fabric weave, skin variation and fixed detail materials. (256² maps rebuilt; fabric
+      now uses a 4× UV weave and skips baked per-character AO, removing the portrait blotches;
+      skin/hair/gear keep AO. Comparison `sheet_npc_baseline_compare-texuv.jpg`.)
 - [ ] Re-bake AO where geometry changes; verify the 256² maps and material wiring.
 - [ ] Audit library props and UI/card/icon textures at their actual screen sizes;
       remove blurry/oversized or unused textures where safe.
