|
||||
- Visual alignment: start/venue menu, pause, settings, shift review, radio, wand, inspection, timeline, HUD target chip/escalation bar, and radial menu now use or match their AI references in `assets/images/ui/`. The runtime art loader (`src/game/ui/art.gd`) falls back cleanly when a file is missing. The wand panel lists the guest's carried items, and multiline HUD/wand strings render real line breaks.
|
||||
- NPC neck/shoulder transition (0.9.4 work): the body graph now uses a fuller neck base, a slightly tapered neck top and a lower shoulder root, giving the head/neck/shoulder line a trapezius slope instead of a thin post. The full character library was rebuilt with a final degenerate-face cleanup; the baseline comparison is `sheet_npc_baseline_compare-body.jpg`.
|
||||
- NPC face-depth pass (0.9.4 work): sclera are recessed and capped by a thin upper lid, and the separate jaw/cheek spheres are replaced by a chin plate and cheekbones sculpted into the head mesh. The full library was rebuilt; the comparison is `sheet_npc_baseline_compare-face.jpg`.
|
||||
- NPC torso/hip transition (0.9.4 work): the pelvis and chest are slightly wider than the waist, giving shirts and jackets a readable taper into the hips without changing the build multipliers or the skeleton. The comparison is `sheet_npc_baseline_compare-torso.jpg`.
|
||||
- NPC proportion audit (0.9.4 work): `tools/npc_proportions.py` measures all eight GLBs against a stylized height/head/shoulder/hip/torso/leg/arm/foot guide. All variants pass; the head and broad-build silhouettes are the nearest upper bounds. Results are in [`npc-proportion-audit.md`](npc-proportion-audit.md).
|
||||
- NPC P1 portrait fixes (0.9.4 work): tourists now hide their photo-pose camera bag outside `photo`/`film` poses, removing the duplicate-backpack silhouette; the backpack gear was rebuilt with flattened, forward chest straps and a fresh AO map. The before/after sheet is [`blender_previews/sheet_npc_baseline_compare-p1.jpg`](blender_previews/sheet_npc_baseline_compare-p1.jpg); the face and remaining clothing/hand work stay open.
|
||||
- NPC visual baseline (0.9.4 work): `src/test/capture_npc_baseline.gd` captures all eight library characters from front, three-quarter, profile, back, full-body and crowd views in a neutral studio (48 frames). The criteria, measurements and ranked gaps are in [`npc-visual-review.md`](npc-visual-review.md); the committed sheet is [`blender_previews/sheet_npc_baseline.jpg`](blender_previews/sheet_npc_baseline.jpg). No model changes were made in this baseline step.
