# Screenshots — demo-map visual review

Rendered captures of **the demo map only** — what a player sees when the demo runs. Generated by [`Tools/render_screenshots.sh`](../Tools/render_screenshots.sh); the PNGs are committed so a reviewer sees exactly what the build rendered.

The review staging map (`/Game/Test/ReviewMap`) is not part of this set: it exists to hold the camera list and the hero detail rig, and it is not what ships.

## How to regenerate

```bash
Tools/render_screenshots.sh --verify
```

Stages the demo shot cameras, runs the game on `/Game/Hollywood/DemoMap`, copies the PNGs into `Screenshots/demo/` and then runs [`Tools/visual_loop.py`](../Tools/visual_loop.py) `--verify` to check that each shot still shows the content its expectation describes. About a minute.

## Status at a glance

Every shot is embedded below, in order, so the whole review happens in this file.

**Verified** is what `--verify` reports: the frame is not blank, is the right size, and has tonal range. **Approved** is the owner's verdict, recorded here. Each shot also has an **expectation** in [`Tools/visual_targets.json`](../Tools/visual_targets.json) describing the content it must show.

- **File:** `demo/review-demo-crossing.png`
- **View:** from the north sidewalk along the crosswalk
- **Expected content:** the designated mid-block crossing (s=130 m, UE X −14956) — zebra bars on the asphalt, south frontage and colonnade behind
- **Verified:** ☑ 2026-11-09 · **Approved:** ☑ 2026-11-09

- **File:** `demo/review-demo-north-buildings.png`
- **View:** across the Boulevard from the south side
- **Expected content:** the two north-side buildings (TCL Chinese Theatre, Madame Tussaud's), full height in frame
- **Verified:** ☑ 2026-11-09 · **Approved:** ☑ 2026-11-09

---

## 5. Retail frontage

![Retail frontage: 6800 Lee Drug and 6806–6820 from across the street](demo/review-demo-retail-frontage.png)

- **File:** `demo/review-demo-retail-frontage.png`
- **View:** north sidewalk, level horizon, 68° lens
- **Expected content:** the retail run beside the hero — 6800 Lee Drug's bronze cornice, mural row and parapet next to 6806–6820's burgundy fascia, pilasters and window storey
- **Verified:** ☑ 2026-11-09 · **Approved:** ☑ 2026-11-09

Read this one against the reference photograph it was modelled from: `Art/reference/retail-neighbours/01-lee-drug-and-neighbor.jpg` (Gb321, CC BY-SA 4.0).

Known gaps in this first pass, recorded rather than hidden:

- **The parapet still reads as a blank band.** It is now two tiers with three deeper reveals, and the step is visible, but there is no profile or shadow line to break the wall — a moulded coping and a modelled reveal need the `0.9.0` façade system.
- **The mural row now reads** (framed plates standing 0.12–0.20 m off the wall), but **the lettering band does not**: it is a plate at 0.10 m and it disappears at 40 m. Wall lettering is a decal/texture problem, scoped in `0.9.0`; no amount of extra plate depth fixed it in the second pass.
- **The corner tower is a plain cylinder with two cap rings** — the stepped Deco profile in the photograph is richer than that.
- **The camera crops the east end** of Lee Drug at 68° from the north sidewalk.
- **6822 Budget is untouched** and still a bare blockout volume: no photograph of it exists.

## 6. Third-person body

![Third-person body: the player pawn seen from behind on the north sidewalk](demo/review-demo-third-person.png)

- **File:** `demo/review-demo-third-person.png`
- **View:** third-person boom, ~6 m behind the pawn, captured with `-thirdperson` so the pawn starts in the third-person rig
- **Expected content:** the player's own visible body on the north sidewalk, seen from behind, with the hero façade across the street
- **Verified:** ☑ 2026-11-09 · **Approved:** ☐ pending

What this shot is evidence for, and what it is not:

- **Implemented and visible:** the pawn carries a visible skeletal body with the warm skin material, and a spring-arm camera with collision testing. The **V** toggle swaps first and third person; the shipped default stays first person and the review passes `-thirdperson`.
- **Not working:** the figure is in **bind pose, arms out**. The idle clip is bound and `PlayAnimation` is called — the run logs `GigLine: playing body clip Character_AnimHuman_rig_GigLine_Idle` — so the call succeeds and the pose does not apply. Tracked in `TODO.md` under "Verify animation plays correctly on the imported rig" with that evidence.
- **Camera collision is implemented but unproven:** the spawn point has open space behind it, so no shot exercises the arm shortening.
- The skin material needed `used_with_skeletal_mesh=True`; without it Unreal silently substituted the default grey, which is what the first capture of this shot showed.

## The iteration loop (uncommitted)

`Tools/visual_loop.py` measures each capture against its reference photograph and turns the deltas into modelling actions for the Blender skill packs:

```bash
python3 Tools/visual_loop.py --compare --iteration 3   # writes Art/reference/iterations/3/
```

That directory is **gitignored**: iterations stay uncommitted until a shot is confirmed, and only confirmed shots are promoted into `Screenshots/demo/`. The feedback file names the affected skill (`blender-modeler`, `archviz`, `materials`, `lookdev`, `camera-cinematography`) so the next modelling pass has a starting point rather than an opinion.

Note the comparison is only meaningful when the shot and the reference frame the same subject — a wide block view measured against a tight façade crop will always report low edge similarity.

## Scene conventions

- **Demo map** (`/Game/Hollywood/DemoMap`): fixed daytime — sun pitch −62 / yaw 120 (intensity 4, warm), sky light 2.6, sky atmosphere, height fog, fixed exposure.
- **Cameras**: elevation shots sit at their target height (pitch 0, so verticals stay parallel) and use a 42–68° lens to fill the frame from across the street.
- **Materials**: every surface carries a look-developed material from `Tools/ue_build_demo_map.py` — noise-blended base colour, masonry coursing, and a generated texture set (`Tools/generate_facade_textures.py`) sampled world-aligned. Explicit roughness and specular per surface type.

## Known cosmetic issues

Every issue is tracked in `TODO.md` under the version that will fix it; an issue with no ticket is a bug in the plan, not a note.

| Issue | Where it is tracked | State |
| --- | --- | --- |
| Hero stone renders pale — the material is a procedural graph and a generated texture set, not a measured surface | `0.9.0` → measured material library | Open |
| Hero façade has no doors at street level left and right of the central bay, and the central-bay elements (columns, stairs, set-back entrance, door frames, signage) are not positioned as the photographs show | `0.9.0` → per-building models, hero façade | Open |
| Nothing may stand in front of the hero façade that blocks it — no awning, no temporary structure | `0.9.0` → per-building models, hero façade | Open |
| Retail parapet has no moulded profile, and wall lettering built as a plate does not read at 40 m | `0.9.0` → 6800 Lee Drug and 6806–6820, second pass | Open (moved out of `0.1.6`) |
| 6822 Budget is a bare blockout volume — no photograph exists to model it from | `0.9.0` → photography gap | Deferred (moved out of `0.1.6`) |
| Third-person body renders in bind pose: the clip is bound and `PlayAnimation` is called, but the pose does not apply | `0.2.0` → verify animation plays correctly | Open (blocks `0.2.0`) |
| Camera collision is implemented but never exercised against a wall | `0.2.0` → camera collision | Open |
| Between kerb and building line the walkable surface is the terrain mesh, not a modelled pavement | `0.6.0` → model the pavement between kerb and building line | Open |

Accepted by the owner, not a defect:

- Banners hang on the column line rather than flush to the wall — that is how they hang in the photographs.

Resolved and removed from this list on 2026-11-09:

- "The El Capitan Theatre has no marquee or blade sign" — `Tools/ue_stage_theatre_trim.py` stages all six trim actors; verified in `/tmp/gigline/theatre-import.txt`.
- "Materials are not yet created in Blender or fully integrated" — contradicted by the scene conventions above: every surface carries a look-dev material built in `Tools/ue_build_demo_map.py`.
