What the first pass got wrong, and what changed:
- The mural plates were placed 0.20 m INSIDE the solid blockout volume, so they
never rendered. Nothing can be recessed into a solid we do not cut: the inset is
now faked by a proud frame with a near-flush plate, and the row reads.
- Detail sat 0.05 m off the wall, under a pixel of depth at 40 m. Trim planes now
stand 0.10-0.20 m proud, and the parapet became two tiers with deeper reveals.
- 6806's parapet started at 0.62 H and left a 4.6 m blank band; the window storey
and parapet moved up to follow the photograph.
- Security bars on the upper windows, twelve fluted fins on the corner tower.
- The trim's stucco/white/glass slots are mapped onto the demo's look materials, so
the walls sit in the same noise/texture family as the rest of the block; the
colour slots sampled from the photograph stay as authored.
- Review camera pulled back and widened to 66 deg so the east end is in frame.
- The scene audit caught duplicate RetailTrim_ actors: the demo builder's clear list
did not include the new label, so every rebuild stacked another copy.
Still open and not fixable by geometry: wall lettering. A plate at 0.10 m does not
read at 40 m, so it moves to the 0.9.0 decal route (TODO.md, Screenshots/README.md).
Models the two retail buildings beside the hero from their own photograph rather
than the generic kit: bronze cornice, mural row, lettering band, stepped Deco
parapet and rounded corner tower on 6800 Lee Drug; burgundy fascia, pilasters,
white-framed windows and banded parapet on 6806-6820. Reference analysis written
before any geometry (Art/blender/retail/ref-analysis.md), every unmeasured
proportion carried into the part report as an assumption.
6822 Budget is deferred, not guessed: no photograph of it exists and the 6.0 x 5.5 m
sliver cannot be read out of the neighbour shot.
Pipeline fixes found on the way:
- render_screenshots.sh called ./Engine/... for the capture step while every
commandlet used the absolute path; set -e killed the script at 127 *after* the
maps were rebuilt, so screenshots silently stayed a day old.
- the facade kit applies to every Frontage_*/North_* actor, so it pasted its own
language over the new modelled facades; it now skips them, and the trim stages as
RetailTrim_*.
- pure bay arithmetic moved to Tools/_common.py so it is unit-testable without
Blender (4 new tests, 82 total pass).
Known gaps recorded in Screenshots/README.md, not hidden: the parapet reads as a
blank band, murals and lettering do not resolve at review distance, the tower is a
plain cylinder, and the review camera crops the east end.
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.
Screenshots re-rendered and approved by the owner.
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).
Completes "Geographic attribution display" for 0.1.0. The demo is built from
OpenStreetMap data (ODbL 1.0) and needs attribution wherever the derived work
is shown, so the credit now lives in the running game, not just the documents.
- AGigLineHUD (C++): plain AHUD::DrawText in the bottom-left draws
"(c) OpenStreetMap contributors" and "Data (c) OpenStreetMap contributors,
ODbL 1.0 - openstreetmap.org/copyright", with a shadow pass so it stays
legible over bright pavement and sky. No UMG widget asset is involved, so a
cook cannot drop the attribution through a missing widget reference.
- AGigLineGameModeBase: HUDClass = AGigLineHUD, so the credit is on by default
in both the DemoMap and the ReviewMap.
- AGigLineShotActor: screenshots are requested with the UI shown, so the credit
appears in every capture under Screenshots/ - the obligation is provable from
the images rather than only described.
Docs:
- THIRD_PARTY_NOTICES records that the attribution is displayed in-game and
where the code lives.
- Screenshots/README documents the overlay.
- TODO marks the item done and narrows the remaining ODbL question to the
shipped-derivative-database posture.
Squash of branch gameplay-attribution-0.1.0 (PR #4).
Completes "Fixed daytime lighting and basic ambience" for 0.1.0. All 14
screenshots approved by the owner.
Lighting rig (Tools/ue_build_demo_map.py):
- Sun pitch -50 / yaw 120, intensity 4, warm (255/245/230), atmosphere sun light
- Sky light 2.6 with real-time capture, sky atmosphere, height fog (density 0.008)
- Unbound post-process volume with fixed exposure (min == max brightness) so a
shot cannot wash out or crush to black depending on how much sky it frames
- Dynamic-only: r.AllowStaticLighting=False plus MOVABLE lights and mesh
components, so the editor's "LIGHTING NEEDS TO BE REBUILT" warning no longer
fires and nothing needs baking
Bugs found and fixed on the way:
- Blender diffuse colours do not survive the FBX -> Unreal import: every site
material arrived white and the terrain arrived with WorldGridMaterial, which
is what actually made the scene look blown out. The demo builder now creates
and assigns M_Asphalt, M_Concrete, M_Ground and M_RoadPaint.
- Only one of the three crossings reached the game: each zebra band was its own
object, so Blender renamed the duplicates .001/.002 and exact-name site
assembly skipped them. All bands are now one Crossing_Markings mesh.
- Demo cameras: street-level sat inside the facade body (rendering its unlit
back face) and the crossing camera aimed at the s=36.6 crossing instead of
the designated s=130.1 (UE X -14956).
- The terrain had no material and imported as a bright default grid.
- Cleared a committed Android File Server SecurityToken (plugin disabled and
shipping-excluded; the value must stay empty).
Docs:
- Screenshots/README.md: one consolidated table for all 14 shots with map,
camera view and description; all approved.
- MEMORY.md: records the material-import, exposure, light_color struct,
band-naming, camera-bounds and lighting-build traps.
- TODO.md: lighting item marked done.
Squash of branch gameplay-lighting-0.1.0 (PR #3).
Root cause of the empty review frames: EditorLevelLibrary.load_level/new_level
are deprecated no-ops in -nullrhi commandlets, so staged actors landed in the
current world and got saved over the wrong map. Switched both map builders to
the LevelEditorSubsystem and reordered the review builder to save ReviewMap
before the DemoMap section (the switch-back to a map that only exists in
memory silently failed, writing demo content over ReviewMap).
Rebuilt both maps, re-rendered every screenshot; user visual check passed.
Screenshots/README.md cube naming corrected (A grounded, B floating), approval
states updated; TODO.md visual-review notes closed. MEMORY.md records the
deprecated-call and save-order traps.
- street_mesh.py: continental zebra markings (0.5 m bars, 0.5 m gaps, 3 m
band) at all three signalised crossings, triangles not quads (FBX SDK
refuses to triangulate the crown-twisted quads), stripes +6 cm above the
DEM so they stay above the road surface; winding flipped so every street
surface faces up (road/sidewalks/markings were 100% down-facing and
invisible in engine once the terrain stopped covering them).
- terrain_from_dem.py: cut a 10.7 m corridor around the Hollywood Blvd
centreline so road, kerbs and sidewalks are not buried under the terrain;
sidewalks themselves cover the transition band, walk-check stays at 0 holes.
- Blender builders save with a writability guard + fatal failure: *.blend
is LFS-lockable and checks out read-only; a failed save previously left
downstream steps building from stale files.
- ue_import_site.py: Crossing_Markings imports with no collision (paint on
the road); ue_build_demo_map.py stages it and chmods the lockable .umap
before saving (save_map silently returned False on read-only maps).
- ue_build_review_map.py: demo-crossing camera moved to the real crossing
(s=130.1 m -> UE -24291,-1340) and fixed the ensure_writable path (was
missing the .umap suffix, so the chmod never fired).
- New C++ AGigLineNPCPerson: reusable NPC/pedestrian prefab built on the MPFB
human. ACharacter capsule half-height 83 cm (total 1.66 m, head top ~1.66 m
so a 1.60 m camera doesn't clip), the character skeletal mesh on the built-in
mesh as the visible body (feet on Z 0), AutoPossessAI for 0.5.0 pedestrians.
Staged at Z 0 in the review scene; captured as review-npc-prefab.png.
- AGigLineShotActor now names screenshots by stable camera name (no list-index
prefix): inserting or reordering cameras no longer renumbers files or orphans
the old ones. Re-rendered all review/demo shots with stable names.
- ue_build_review_map.py: chmod the target .umap before save_map (git marks maps
444 on checkout, silently making save_map return False and dropping stages).
- Screenshots/README.md, ROADMAP, TODO updated for the prefab + stable names.
- DemoMap.umap rebuilt by the render pipeline (north buildings + demo cameras).
- TCL Chinese Theatre (6925) and Madame Tussaud's (6933) exported from the
verified OSM blockout with ue_metric_v1 (export_north_buildings.py), with a
Y-mirror so they land north of the road, across from the hero facade.
- ue_import_north_buildings.py imports + stages them in the DemoMap as
North_TCL_Chinese / North_Madame_Tussauds (TCL Y 1802..9431, Tussaud's
1888..7586; hero at Y -1450, road centreline ~0).
- render_screenshots.sh now also runs the DemoMap capture pass; added a
demo-north-buildings camera, so the new buildings get a review shot.
- README/roadmap updated; flat facade materials pending the 0.1.4 patch.
- mpfb_character_export.py: new --pose idle folds the A/T-bind arms down to
a relaxed standing rest pose (baked via pose.armature_apply before export);
new make_diffuse synthesizes a warm skin-tone diffuse with a darker
shorts-suggestive band, replacing the Cycles v2-skin bake that came out
black and was slow at 1024^2.
- write_png now encodes from img.pixels via numpy (fast) because img.save()
writes black for an in-memory image.
- Re-exported idle character, re-imported to /Game/Test/Character (138 bones,
warm M_Character_Export/T_Character_Diffuse); removed stale T_Skin_Diffuse.
- Untracked the review PNGs again: the Screenshots/ gitignore rule had been
dropped and the parallel session had committed the PNGs, against the
AGENTS.md 'never commit the PNGs' rule. Restored the ignore rule; only
Screenshots/README.md stays tracked.
- README/roadmap/memory updated; review-01-character re-pended for approval.
Tools/ue_build_demo_map.py builds /Game/Hollywood/DemoMap: sun, sky, the hero
facade on the building line, six site meshes imported with collision, and a
player start on the north sidewalk. Tools/ue_import_site.py imports the site
FBXs; terrain, road and sidewalks use complex-as-simple so a simple hull cannot
ramp over the kerbs. Art/blender/site/export_site_fbx.py exports one FBX per
object so each can carry its own collision.
Reset (R) and pause (Escape) join the character and the input context: reset
restores the spawn transform and clears momentum, pause is a real game pause that
releases the cursor. DefaultInput.ini captures the mouse on launch.
Three placement defects found by measuring the imported actors rather than
trusting the plan: the spawn was on the wrong sidewalk because the FBX flip
inverts north, a mirror I added to the exporter double-corrected an already
correct sidewalk, and the street meshes only carry part of the north walk - the
rest is terrain.
The portal detail shot failed for a modelling reason, not a camera reason: the
doors were 0.1 m panels on a solid plinth, so they read as shading. The plinth is
now four piers plus a lintel band, with a 1.2 m reveal, stone jambs and lintels
standing 0.10 m proud and three mullions per opening. review-06 frames them from
8 m at eye height.
Two defects fixed while doing it: the jamb boxes hung 0.15 m below the pavement,
so the facade imported with min Z -15 cm; and a rebuild run against a read-only
.blend silently skipped the save, which is why screenshots kept showing the old
geometry.
Tools/sibling_asset_audit.py reads the sibling security-game project's prop
library straight from the GLB headers: 20 street props, 11.8k triangles, every
one with a Blender source. The 50 .blend sources are copied to
Art/props/blender_src/ with a manifest; nothing is imported into Unreal yet. Its
building meshes are deliberately not taken - they are Godot GLBs built around a
29.6 m facade that this project measured at 25.75 m.
The facade proportions were wrong against the photograph: 5.7 m of blank wall
above the capitals. Entablature is now 3.4 m, parapet 2.2 m, with architrave and
cornice bands and square pedestals, so the elevation reads as layered stone.
Roadmap gains two sections: 'Review scene and player placement' (this pass) and
'Character development' (follow-on). The camera list is now one table of
(name, location, target) with look-at rotations computed from the pairs, so a
camera cannot drift out of aim when one number changes.
New shots: player-placement (the real pawn, staged in the build script),
ground-contact (knee height, feet on the plane), shadow-compare (floating vs
grounded cube from a low angle), and hero-portals (whole elevation).
The review floor grows to 160 m so the facade stands on ground rather than the
horizon band. Retired: the first-person shot.
Honest gap recorded in the roadmap: the hero portals sit behind the colonnade and
do not resolve from the review floor; that needs a camera on the plinth or a
portal rebuild, not another angle.
The review floor was a 5 cm slab centred 50 cm down, so the character floated
1.8 m above it. The floor is now 90 m x 90 m x 10 cm with its top face at Z 0 and
the character measures Z 0..83 cm - feet on the plane.
Two cubes only: A on the ground as the contact/scale reference, B held at 2 m so
its cast shadow separates from the body for comparison. The scale-cubes camera
was still aimed at the old three-cube row and now looks at both from the south.
Screenshots are committed per the owner's instruction, and .gitignore no longer
excludes them.
Tools/hero_facade_build.py builds the north elevation parametrically and writes
a JSON report naming the evidence behind every part: the 25.75 m frontage and
14.5 m height are measured, the 4.96 m column bay comes from the sibling notes
and matches that frontage, the three portal flights follow the photographs (five
risers, overturning the inherited eight-step, 12 m wide claim), and the rest is
labelled assumption.
Tools/ue_hero_facade_import.py imports it with the ue_metric_v1 preset
(2604 x 1257 x 1450 cm, 1892 tris, 4 materials) and places it on the measured
building line of /Game/Hollywood/DemoMap.
Two new review shots at review-04 and review-05, both pending approval. Camera
placement cost four renders: the first two sat inside the facade body, and the
frontage faces Unreal -Y, so a camera has to stand at Y < -1450 cm, not north of
the building line in project terms.
AGigLineCharacter: 1.75 m capsule, 1.60 m eye camera, 4 m/s walk, mouse look
scaled in degrees per second (no double DeltaTime), jump. Loaded ahead of a
Blueprint so the demo is playable with no assets wired by hand.
Tools/ue_create_input_assets.py builds /Game/Input headlessly: five 1D actions
and an 11-mapping context. One action per direction instead of per-key modifiers,
because modifier objects do not survive the save path here: a mapping's modifier
array serialises None, and dimensioning a 2D move with per-key axis masks would
need exactly those modifiers. The cost is four action assets rather than two.
Also adds a fourth review camera at eye height and documents it; its approval is
pending.
- AGigLineShotActor (dev-only): walks a fixed camera list in -game mode,
captures via FScreenshotRequest, quits. Test content only.
- ue_build_review_map.py builds /Game/Test/ReviewMap from current content
(gray floor, key light, sky, MPFB character, 1 m scale cubes).
- render_screenshots.sh: build map -> run game -> collect PNGs into
gitignored Screenshots/.
- Screenshots/README.md (committed) describes each capture with approval
state; AGENTS.md gains the visual-review instructions.
