Adds Tools/facade_detail_concepts.py: generates architectural detail plates from a
local reference photograph through OpenRouter's image models. Spec-driven (eight
studies: door recess, entrance, column order, entablature/cornice, parapet/motto,
window rhythm, street wall, banner), never overwrites (writes -vN), writes a
.refgen.json sidecar (model, prompt, source photo, SHA-256) per image, and keeps
all output under the gitignored Art/reference/facade-details/ - local only, never
shipped. Stdlib only; http 429/5xx back-off; refuses to write a sidecar containing
the token. 11 tests cover the study table, prompt assembly, next-free naming,
data-URL decoding (both response shapes plus a refusal) and the local-only rule.
Measurement pass on the plates: the hero window panes were at Y -1.98, i.e. 1.44 m
in FRONT of the wall (Y -0.50) and ahead of the column line, so the glazing floated
in the colonnade instead of reading as openings behind it. Moved to Y -0.56; hero
rebuilt, re-imported, DemoMap rebuilt, full screenshot set re-rendered.
Docs: Tools/README row, Screenshots README known-issues entry now records the fix.
Measured from the built mesh, the colonnade (columns + capitals) was 6.90 m of the
14.50 m elevation = 47.6 %: the entablature (3.40 m) and parapet (2.20 m) were
using 5.60 m of the height. Thinned both to 3.00 m and 1.80 m in
hero_facade_build.py, which lifts the colonnade to 7.70 m = 53.1 % - inside the
50-60 % band - with the envelope, motto band and medallions unchanged relative to
the parapet.
Hero rebuilt, re-imported (bounds 2604 x 1257 x 1450 cm), DemoMap rebuilt and the
screenshot set re-rendered for review. Hero part report updated (columns 7.45 ->
8.25 m, entablature 3.40 -> 3.00 m).
TODO: colonnade item closed. MEMORY records the FBX-vs-blend --out gotcha.
The reported fall-through was a misdiagnosis: the player never fell. The
imported Terrain_DEM had only a bounding-box simple collision proxy, so a
downward trace anywhere in the block hit the terrain at Z 819 (the mesh
bbox max) and the street sat under an invisible 8 m lid. Standing on that
box looked plausible, which is why it read as working.
- add UGigLineAssetTools (C++): force CTF_UseComplexAsSimple on a static
mesh. UE 5.8 dropped bUseComplexAsSimpleCollision and Python cannot set
the flag; the builder also saves the asset, since the flag lives there
and a map-only save silently reverts it.
- spawn (-13336, -1150, 600): inside the carved corridor (the cut is a
10.7 m half-width around the road centreline), lands on the road at 456.
- fix ResetToStart returning to the mid-air PlayerStart captured in
BeginPlay: StartLocation is now captured on the first grounded frame.
- HighResShot 1280x720 instead of "1280 720", which is a multiplier.
- add -qaselftest: scripted walk/reset/pause on a core ticker plus a
swept ground transect. Results: walk 746 cm/2 s with Z steady, reset
0 cm from spawn, pause/unpause 1/0, transect 84 samples 0 holes.
- rebase onto main, keeping the frontage materials and placement fixes.
Adds the five remaining verified south-side buildings to the demo block
(6922, 6902, 6838 El Capitan Theatre, 6822 Budget, 6806-6820, 6800 Lee Drug),
exported in place from the OSM blockout by Tools/export_block_frontage.py,
imported to /Game/Hollywood/Frontage/ and staged by the demo builder with the
look material set (stone for the theatres, stucco for the retail run).
Adding neighbours exposed a pre-existing placement bug that was invisible while
the hero facade stood alone in an empty field:
- UE south is +Y here (south sidewalk Y +718..+1447), but the hero sat at
Y -1450 on the NORTH side of the street.
- It was also at X -12024..-9420, 26 m east of the 6840 footprint; the frontage
gap between 6902 and 6838 is X -14591..-12082.
- The two north-side buildings were on the SOUTH side, because their exporter
mirrored Y.
Fixes: hero moved to X -13336 / Y +1307, inside its frontage gap; the frontage
and north-building exporters no longer apply a Y mirror (the FBX preset already
lands Blender -Y south on UE +Y south); player start and demo cameras moved to
the north sidewalk looking south; sun raised to pitch -62 so both frontages read
instead of the north side silhouetting.
Result: the demo is a street - continuous south frontage with the hero in it,
both sidewalks, the road with the designated crossing, and the north-side
buildings across the road.

Squash of branch frontage-block-0.1.0 (PR #6).
Completes "Materials and look development for all exported assets". Every
exported surface previously carried a flat Constant3Vector fill, which read as
plastic. ensure_material() in Tools/ue_build_demo_map.py now builds a
procedural material per surface:
- base colour blended between two shades by world-space noise
(WorldPosition -> Multiply -> Noise -> Lerp -> BaseColor) for large-scale
variation,
- an explicit roughness and specular so the surface type is readable.
M_Asphalt 0.92, M_Concrete 0.88, M_KerbConcrete 0.85, M_Ground 0.98,
M_RoadPaint 0.62, M_FacadeStone 0.72, M_Stucco 0.86
Site meshes take their material by mesh name; the hero facade and the two
north-side buildings take theirs by actor label, so they are covered even
though other scripts stage them. Materials are deleted and rebuilt on every
run, so a look change cannot be masked by a stale asset.
Result: the facade reads as warm stone with surface variation, asphalt as dark
asphalt with grain, concrete and kerbs lighter and matte, and the north
buildings in stucco instead of flat grey.
Screenshots re-rendered and approved by the owner. The richer texture-based
pass (baked/procedural brick_facade, seamless_concrete, glass, material
instances) stays in the 0.1.4 facade patch.
Squash of branch materials-lookdev-0.1.0 (PR #5).
