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; 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

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 --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.

6	Third-person body	☑ 2026-11-09	☐ pending

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 describing the content it must show.

1. Spawn view

• File: demo/review-demo-spawn-view.png
• View: north sidewalk, 14 m back, level horizon
• Expected content: the whole south block — the neoclassical hero façade between its neighbouring buildings, both sidewalks and the road in the foreground
• Verified: ☑ 2026-11-09 · Approved: ☑ 2026-11-09

---

2. Street level

• File: demo/review-demo-street-level.png
• View: eye height, north side
• Expected content: the hero colonnade with the adjacent frontage buildings either side, shopfronts at pavement level
• Verified: ☑ 2026-11-09 · Approved: ☑ 2026-11-09

---

3. Crossing

• 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

---

4. North buildings

• 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

• 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

• 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:

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.
