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.

The shot list

Each shot has an expectation in Tools/visual_targets.json — the content the capture must show — and a verification state produced by --verify: it fails if the frame is blank, the wrong size, or has no tonal range.

Approval is per shot, in the table above (owner review of the 0.1.4 set, recorded in Docs/reviews/0.1.4-review.md). Add a row when a shot is added; remove the file in the same change when a shot is retired.

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 42–55° 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

• Hero façade renders pale: the stone material is a graph and a texture set, not a scanned surface (the 0.1.4 façade pass is in progress).
• Banners sit on the column line rather than flush to the wall (they hang on the columns in the photographs, so this is acceptable).
• Between kerb and building line the walkable surface is the terrain mesh, not a modelled pavement.
• The El Capitan Theatre has no marquee or blade sign yet — the feature that makes it read as itself.

0.1.6 retail frontage — what to look at

Shot 5 is the review shot for this pass. Read it against 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 reads as a blank white band. It is modelled as one 2.18 m wall with four 0.10 m reveal strips, and at review distance the strips disappear into the wash.
• The mural row and lettering band barely read. They are shallow plates (0.06–0.08 m) on the same plane as the wall; they need either depth or a decal before they read as the photographs' black-framed panels.
• 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.
