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.
Completes the stable-name rename: removes the 13 old numbered review/demo
screenshots so Screenshots/ contains exactly the stable-named set, matching
gameplay-crossing-0.1.0.
The stable-named screenshot set (renamed in the NPC/character work) is
review content that does not belong on the gameplay-crossing branch. Bring it
onto main directly:
- renames all 9 numbered review shots to stable camera names
(review-overview, review-character, ... review-hero-facade-oblique)
- adds the download-north-buildings demo shot + review-npc-prefab
- README updated for stable naming and the new NPC shot
- Tools/judge_screenshot.py: judges a screenshot against an expected-scene
description via OpenRouter multimodal image understanding, reading
OPENROUTER_API_KEY from the ignored .env. --image+--expect for one shot,
--shots to run every review shot in Screenshots/README.md. Returns a
{verdict, confidence, reason, missing} JSON.
- Documented in AGENTS.md (Visual review pre-check step) and Tools/README.md;
recorded the OpenRouter payload format gotcha in MEMORY.md.
The skill-pack entry was swept into another session's commit before it could be
committed on its own. Notes that a shared worktree can commit a shared file for
you - or drop the edit if the file is overwritten - and that git log -S is the
way to check before assuming the edit was lost.
- 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).
0.5 m white bars with 0.5 m gaps across a 3 m band per crossing, laid
1 cm above the road surface. Makes the mid-block crossing (OSM way
385648319, s=130.1 m) a designated crossing in game. Metadata audit
passes (1 sidecar, 0 problems).
Split the former ROADMAP.md checklists into TODO.md, which now holds
all actionable work and progress marks. ROADMAP.md keeps milestone
goals, scope, and release gates as prose with no checkboxes.
Update AGENTS.md, Docs/, Geo/README.md, MEMORY.md, and README.md to
point to the new file roles.
- Drop the /Screenshots/* gitignore exclusion so review PNGs are committed
(LFS-tracked) alongside the review README.
- AGENTS.md Visual review: PNGs are now committed, not kept only on disk.
- 13 review/demo screenshots tracked (25 MB LFS).
- Screenshots/README.md: collapsed per-shot blurbs into one approved
review-map table + one demo-map table; removed the duplicate
hero-facade-front/oblique entries (leftovers from an old camera list that
duplicated review-07/08) and the trailing duplicate 'known issues' block.
- Removed the three orphan PNGs (review-03-first-person, review-04/05
hero-facade) that no longer match the camera list.
- ROADMAP.md: fix stale 'review pending' on character and hero-facade items
(now approved), and point facade review refs at review-06/07/08.
- 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.
Coordinator decision 2026-11-07: 0.1.0 is first-person-only (capsule +
camera, no visible body). The MPFB character (idle pose + warm skin, done)
is reframed as the reusable NPC/pedestrian prefab for 0.2.0+ / 0.5.0, not
wired into the AGigLineCharacter pawn. Roadmap character + 0.2.0/0.5.0
sections updated; no engine/asset changes.
- 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.
README rewritten around the actual state (walkable DemoMap, blockout facades,
planned patches); Tools/README now lists all seventeen tools by role; build.md
gains the content pipeline table and the two enforced rules (one unit conversion,
collision decided at import). Setup gains a content-pipeline row, the toolchain
state notes the demo level exercises the engine path, release checks record the
Blender pre-check that backs traversal, PLAN points at ROADMAP/MEMORY/Screenshots,
and THIRD_PARTY_NOTICES gains rows for the hero facade and the candidate props.
Also fixed the last stale reference to Geo/scripts in MEMORY.md - a sweep found
old paths in six documents after the tool move, which the memory entry now warns
about.
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.
All nine review shots approved. Roadmap gains the defects the Blender pre-check
already knows about rather than rediscovering them after release: 0.1.1 now names
the 15.8 cm sidewalk edge step, the ~10% crossing ramps, the missing collision
authoring pass and the unverified kerb height. A new 0.1.4 patch plans proper
building facades explicitly - facade kit, procedural materials, Blosm setupScript
styles, hero detail, El Capitan Theatre - and states that the existing geometry is
kept, so shipped blockouts cannot be mistaken for finished architecture.
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.
Geo/tools/ is now every geographic script, with Geo/README.md documenting each
one; the Blender-side builders moved beside their outputs in Art/blender/*/ and
import their helpers from Geo/tools/osm_common.py.
That module gains to_unreal_local() and to_blender_local(): the only place in the
repository that multiplies metres by 100, so a second silent scale cannot be
introduced. block_height_report.py adds height provenance for the block — 3 of
15 buildings have no height data and render at a placeholder 6.4 m.
asset_metadata.py writes and audits <asset>.geo.json sidecars; four now exist
(hero-facade, terrain, street, blockout) and the audit recomputes each centre from
the origin, failing anything that disagrees.
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.
Memory gains the camera-side, centre-origin, read-only-map and screenshot-tracking
traps this pass cost. The asset production claim is released: the hero facade
first pass exists and awaits screenshot approval, so the section is free for the
next owner.
AGENTS.md requires the PNGs to stay on disk with only Screenshots/README.md
tracked. Four shots had been committed; they are removed from the index and the
ignore rule restored, so the next review run cannot add binaries by accident.
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.
Initial setup is complete: setup.md opens with a per-section status table and
drops the stale blockers, toolchain.md records that every pin has been exercised
on real work (engine compile + package, Blender/MPFB/Blosm assets, PROJ origin),
and MPFB's load-and-export check moves from pending to verified. Records the one
unexercised path — a fresh checkout — as a v0.1.0 release check.
