The motto band and moulded surround had the same burial as the medallions: offset
0.06 left their front face at Y -0.44, inside the 1.2 m-deep parapet, so the
'inset panel with a moulded surround' never rendered. Only the inscription (moved
to 0.40 in the previous commit) read.
- Band recessed at offset 0.34 (Y -0.16), surround proud at 0.43 (Y -0.07),
inscription stays 0.40 (Y -0.10).
- Band is now light stone (was stone_dark): a dark band at the parapet face would
have sat directly behind the dark inscription marks and swallowed them. The
reference is dark incised lettering on a pale band.
- Removed the dead duplicate 'Hero_MottoBand 0.40' entry - the earlier 0.06 match
won, so the 0.40 was silently ignored.
Rendered and judged; the advisory judge no longer flags the band.
The medallions were not just flat - they were buried. seat_on_front put
Hero_Medallion at offset 0.08 (front Y -0.42) while the 1.2 m-deep parapet stands
at Y -0.15, so both discs sat inside the parapet and never rendered. The motto
band and surround have the same burial (offset 0.06) and are a separate follow-up.
- Three stepped layers per medallion with per-layer prefixes so seat_on_front gives
each its own stand-off: Rim (0.55 m, dark, offset 0.36 -> Y -0.14), Field
(0.38 m, light, offset 0.43 -> Y -0.07), Boss (0.15 m, dark, offset 0.50 -> Y 0.00).
A single Hero_Medallion prefix would both flatten the relief and (via startswith)
swallow the specific prefixes, so it is removed.
- Moved from +/-6.2 (inside the inscription text, which spans +/-6.87) to +/-9.8.
- Fixed Tools/review/hero_iterate.sh, which still had the pre-tools-move
'cd dirname/..' and landed in Tools/ instead of the repo root.
Rendered and judged; the advisory two-model judge (no, 0.93) no longer flags the
medallions. Owner review pending.
The reference's most distinctive architectural feature is three lines of incised capitals across the attic.
inscription() lays 112 letter marks in three lines, in the shadow stone so they read as dark incisions at 45 m
rather than disappearing into a same-colour relief - which is exactly what the first attempt did.
Positioning was the lesson: the parapet is 1.2 m deep and stands in FRONT of the wall plane, so marks seated on
FRONT_Y were hidden behind it and rendered invisible. They are now seated on the parapet face (FRONT_Y + 0.40),
which is where the reference puts the lettering too.
Still open in the architectural pass, recorded in TODO.md: medallion relief (the discs are flush and empty),
banner lettering (needs a texture, not geometry), and depth on the capitals and window grilles.
Rows 4-6 re-rendered and pending.
The owner rejected the previous pass on three counts - too saturated, too dark, and the albedo was wrong for the
building. All three were true, and the reason the colour work kept missing is that the albedo never reached the
material: import_albedo() resolved the repository root one level short after the tools move, so every 'stone'
render was the flat tint alone. That is fixed first.
Then measured instead of guessed: the reference's sunlit stone samples sRGB ~0.49 (linear ~0.19), attic
highlight ~0.75, shaded recess ~0.43, and it is nearly neutral, not warm. New albedo generated for a pale
low-contrast marble-limestone ashlar (two checkpoints compared, AlbedoBase won) and the tint moved to
(0.47, 0.455, 0.43) with the shadow at (0.30, 0.29, 0.27), which lands lit stone around 0.62 sRGB - brighter
than the last pass and close to the photographs.
The elevation now reads as pale, low-saturation concrete/marble with thin-jointed ashlar. Row 4-6 re-rendered
and pending. The architectural pass the owner also asked for - carved inscription, medallions, banner lettering,
capital and grille depth - is untouched and recorded as the next step.
THIRD_PARTY_NOTICES carries the new seed and prompt.
The generated ashlar albedo never showed for two reasons that had nothing to do with the material graph,
which was verified correct the whole time (TextureSampleParameter2D -> Multiply -> Base Color, colour sampler,
texture set, 6x UV tiling):
1. **The map overrode every hero slot.** The generic per-slot material pass in ue_build_demo_map.py assigned
the facade KIT's flat stone to every actor whose slot names looked like stone, banner, glass - including
Hero_Facade. Whatever the import authored was replaced at map build time. The hero is now excluded and gets
its own materials.
2. **Mesh slot assignment does not persist.** Assigning to mesh.get_editor_property('static_materials') returns a
copy; after a reload the mesh still pointed at the original imported materials (measured twice). Component
level overrides do persist in the saved map, so apply_hero_materials() sets them in both builders.
The elevation now renders as coursed, grainy warm limestone with banners, window bays and recessed portals.
Rows 4-6 re-rendered and pending review; the comparison plate is regenerated. Still missing against the
reference: carved inscription, medallion relief, banner lettering, crimson banner tone. The two-model judge
returns no/no (0.90/0.95) - it wants the text and detail that are still absent, which is at least the right
complaint this time.
Investigated the count difference from the e2e run and it is the opposite of a regression. The rebuilt map
holds 409 actors: 72 site meshes, 310 facade-kit pieces (the kit tool reports 'placed 310 kit pieces'), six
frontage buildings, lights, cameras and the player start. The previous 600 carried the duplicated staging that
the prefix-only clear used to leave behind; ue_audit_scene.py on the new map reports 0 failures and no
duplicate actor labels.
Captures were re-rendered against this map.
The e2e asset check now completes: PASS on all six steps - empty maps 9 s, demo build 10 s, review build 9 s,
captures 80 s, judge 388 s, review file. Four breakages from the folder move had to be fixed first:
- ue_placement and ue_common are siblings of the scripts that import them, but the rewrite put only the tools
root on sys.path, so every Unreal commandlet died with ModuleNotFoundError. Both paths are inserted now.
- render_screenshots.sh resolved the repository root one level up, so commandlet paths became Tools/Tools/...
and the capture step failed in 0 s.
- the driver treated a result file left by an earlier run as success, which is how a ten-second 'demo build'
passed without building. Result files are unlinked before each step and child output streams to a per-step
log file rather than a pipe.
- two editors on one project hang instead of failing, so the driver refuses to start while one is running.
Also corrects ue_recreate_maps.py: LevelEditorSubsystem.new_level() refuses a path whose package is still in
memory and delete_asset() leaves the file on disk, measured create->delete->create returning False. The step
now loads each map, destroys every actor, saves, and reports the count it left (0), which is the property the
builders actually need.
Open question recorded in TODO.md: the rebuilt map holds 409 actors and 613 KB against 600 and 886 KB before,
and the ~190 missing ones look like the facade-kit and theatre-trim placements that run as separate steps.
Used the workflow integration from the previous step for real: generated a warm limestone ashlar albedo
with two profiles compared (AlbedoBase 17.04 vs Krea-2 13.90, AlbedoBase won), saved it as
Art/textures/generated/T_FacadeAshlar_AI.png beside its provenance sidecar, and imported it to
/Game/Hollywood/Textures.
ue_hero_facade_import.py now imports that albedo and, for the two stone slots, builds a material with
TextureSampleParameter2D -> Multiply(tint) -> Base Color, tiling the UVs 6x, so the map carries the coursing
and the tint keeps the value inside the reference's range.
Two real bugs fixed on the way:
- the albedo path was resolved against unreal.Paths.project_dir() (Game/GigLine), not the repository root, so
the import silently skipped;
- the authored materials were never saved - only the mesh was - so after a reload the slots pointed at
nothing and the elevation fell back to one default colour.
Honest status: the nodes are verified present and saved (Constant3Vector, TextureSampleParameter2D,
TextureCoordinate, Multiply) and the source mesh has UVs, but the render still shows the flat tint. Recorded
in TODO.md with the next probe: read the compiled Base Color pin instead of the node list.
THIRD_PARTY_NOTICES.md gains the AlbedoBase row (commercial use, credit required).
Iterated the loop five times against Art/reference/hero-masonic/. What took the iterations was the material,
not the geometry:
- M_FacadeStone in /Game/Hollywood/Site is the KIT stone; the hero does not use it, so warming it changed
nothing.
- The hero's materials come from the FBX and live at /Game/Hollywood/ElCapitan/M_Facade_*. Unreal keeps an
existing material asset when an FBX referencing it is re-imported, so a Blender colour change never
arrived.
- Deleting those materials before the import broke the mesh's slots: one colour, no banners, no windows.
The working step is tint_imported_materials(): import normally, then author one plain Constant3Vector
material per facade slot with the colour sampled from the reference, and assign it to the matching slot. The
elevation is now warm sandstone with ashlar coursing, three red banners, two window bands and three recessed
portals with steps.
Also: the portal's solid stone reveal z-fought with the door leaf and read as stripes, so the recess is
carried by jambs, lintel and shadow; banners are 1.35 x 6.2 m hung from 7.2 m instead of 1.55 x 5.4.
Loop iteration 5 verdict is still 'no': it wants the carved inscription, medallion relief, a crimson banner
tone and visible window grilles - all recorded as the next iteration. Rows 4-6 are pending review with the
new captures and two comparison plates.
Tools/hero_iterate.sh runs the whole chain - chmod the Blender files, build, import, render, judge, plate -
and fails loudly at each step with its log under /tmp/gigline. Tools/hero_compare.py builds the side-by-side
plate (reference | rendered, one height, labelled); two are committed for review.
This pass: the stone is warmer in Blender (0.66/0.60/0.48 against the near-white blockout) and the banners are
1.35 x 6.2 m hung from 7.2 m, matching the reference proportion instead of the 1.55 x 5.4 that sat too low and
too fat.
Iteration 1 judge verdict, confidence 0.9: lacks warm sandstone, lacks fluted column detail, banners wrong,
no doorways, no inscription or medallions. Checked against the plate, two of those are wrong (120 flute
strips exist and cast shadows; three 1.2 m deep doorways with steps exist and read black) and three are real.
The split is recorded in TODO.md with the next action for each - the important one being that the stone colour
must change in the UE material (ue_hero_facade_import.py), not in the Blender material, which the render does
not use.
Every .blend under Art/ was read-only from the checkout, and a Blender save then fails with 'Cannot save
blend file ... is not writable'. In Tools/hero_facade_build.py the save runs BEFORE the FBX export, so the
old FBX was silently reused and a build could look successful while changing nothing. All 20 .blend and
.blend1 files are now writable and 'find Art -name *.blend ! -perm -u+w' returns nothing.
Re-rendered the full capture set afterwards. The pixels are unchanged, which is the expected result and worth
writing down: render_screenshots.sh renders the IMPORTED Unreal assets, so a Blender change needs
build -> import -> render. Chmod alone cannot change an image.
Also commits the asset state today's imports and the collision-hull clearing produced (67 site meshes, 8
textures, 6 theatre meshes, the demo map), after verifying the walkable demo is unaffected: the player still
stands on Sidewalk_North_07 at 158 cm with feet at 161.
Art/reference/hero-masonic/ (15 images, git-ignored) replaces the single Wikimedia photo as the source of
truth. Two front elevations drive this pass: 02-masonictemple01.jpg, a clean street-level frontal, and
06-el-capitan-theater-frontal-fachade.jpg; 05-hollywoodmasonictemple-1922.jpg records the original masonry.
Changes:
- the blank Hero_Stylobate_LintelBand across the portals is removed - the reference has open doorways with
steps, and they now read as three dark openings with banners above them;
- rustication(): five ashlar courses from the pavement to the portal heads, 4 cm joints proud of the wall;
- balustrade(): bottom rail, top rail and 38 balusters along the roof edge, where the reference shows a
cresting and railing.
Still missing against the same references, and recorded: warm sandstone instead of flat pale stone, lattice
grilles in the window bays, the carved inscription, and medallions that do not read at distance.
The blend is read-only after a checkout - chmod u+w first or the save fails silently and the FBX is never
written, which happened once here.
Rows 4-6 re-rendered and pending review.
The three hero captures showed a plain block with six columns because every applied detail sat BEHIND the
wall's front face, inside the solid mass:
Hero_Banner_1 y -1.08..-1.02 (55 cm inside)
Hero_Portal_1 y -2.35..-1.15 (2 m inside)
Hero_Window_1_1 y -0.60..-0.52 (2 cm inside)
The colonnade, cornice and dentils happened to protrude, which is exactly what the shots showed.
The depth is now stated once, in hero_facade_build.py: FRONT_Y is the wall's front face and
seat_on_front() moves every applied part until its street-facing face sits at FRONT_Y + offset - 8 cm for
banners and jambs, 5 cm for entablature and cornice, 3 cm for window panes, 4 cm for mullions, 10 cm for
portal signs. It reports what it moved, 99 parts.
After re-export, re-import and re-render the front elevation now shows the three red banners, the two
window bands, the dentil course and the portals. What is still missing against the reference: rusticated
banding on the stone, lettering on the motto band, grilles in the windows, a balustrade on the parapet, and
the blank lintel band across the portals that the reference does not have.
Rows 4, 5 and 6 are back to pending for review because the images changed.
Instrumented the movement component so the write is caught at its source rather than inferred from the
actor: a UGigLineVehicleMovement subclass is substituted for the stock component through
AWheeledVehiclePawn::VehicleMovementComponentName, and it logs CreateVehicle(), the first UpdateState and
the component tick.
mover tick: Z 661 -> 1143 -> 1443 -> 1718 ..., output null, wheels 0
physics OFF at 3 s: Z 2247, and it does not move for a whole second afterwards
profile: t=0.25 Z=515 vZ=-8 | t=0.75 Z=920 vZ=-22 | t=1.25 Z=1287 vZ=173
Two conclusions:
1. The mesh's physics state IS what moves the actor - switching physics off freezes it at once.
2. It moves WITHOUT VELOCITY: position rises ~700 cm/s while vZ oscillates around zero. That is a
kinematic teleport, not an impulse and not a force - which is exactly why gravity, mass and
penetration all measured clean. The vehicle-state output is null throughout, so the teleport comes
from the Chaos layer driving the body kinematically while the vehicle itself was never created.
Pawn parked, captures regenerated so the demo stays clean.
Owner review: rows 1, 2 and 3 show the mannequin about 2 cm too high; rows 8 and 9 show nothing wrong.
The staging height moves from 8 cm to 6 cm above the floor plane (floor_z on the mannequin's
sit_on_floor call, which now logs +6.0), and rows 8 and 9 are approved. Rows 1, 2 and 3 go back to
pending with the change noted in the table, since the image is what changed.
Captures regenerated.
The pawn was found again after a cleanup removed its staging, and the diagnostic answers the
zero-wheel question with a bigger one: with the pawn present the actor is launched to Z 1993 cm - 18 m
above the ground it stands at 150 - and still reports 0 wheels.
GigLine vehicle diag: mesh=1 simulating=1 physasset=yes setups=4 wheels=0
GigLine vehicle: settled at Z 1993 cm, simulating=1
Wheels are only created inside CreateVehicle() when the physics state produced a vehicle, so the
chassis body is the suspect rather than the wheel setup: PA_Vehicle_Sedan has one box on the root bone,
and a body that starts intersecting geometry is the usual reason a vehicle pawn launches itself.
Parked rather than shipped: the pawn is not staged, the visible car stays as panels, and the physics is
'Vehicle physics - Chaos rig' in TODO.md with the evidence and three concrete steps. The demo no longer
carries an 18 m flying car in its captures.
Owner review of the last set:
1, 2, 8, 9 rejected - 'mannequin still too low'
14 approved, but 'floating, only maybe 2 cm too high'
The mannequin correction had been a no-op: actor bounds on a freshly assigned skeletal mesh read as
zero, so sit_on_floor returned +2 cm while the soles sat level with the floor plane. It is now raised
8 cm, which puts them clearly above it, and the four rows are back to pending for re-review with that
noted.
The player start drops 2 cm (258 -> 256) for row 14.
Also repaired the four table rows: a cell-index mistake in the previous edit had emptied their item
links.
The review notes named the same class of problem in six rows: things sitting a little too low or too
high in the floor. They were all hand-typed staging heights, and every one was wrong by a different
amount - the mannequin's root is not at its soles, the resting cube's origin is not at its base, the
vehicle's wheels are 2 cm below its panel origin.
sit_on_floor() measures the actor's bounds and shifts it so the mesh's lowest point lands 2 cm above
the floor plane, and reports the correction it applied:
MPFB character +2.0 cm
ScaleTest_A -48.0 cm (it was floating)
vehicle wheels +2.0 cm
The DemoMap vehicle shot was rejected as 'no vehicle in the scene': both vehicle cameras were still
aimed at the car's old position, so re-aiming them at Y -1450 brings it back into frame.
Status table notes record each fix; the hero-facade rework and the shadow-compare expectation are
left for the owner's next review.
The road was never mis-modelled: a 279 m strip imports with ONE auto-generated convex hull, and a
convex hull's top is the strip's maximum height. A downward trace therefore landed at 366 cm - a flat
lid about 2 m above the visible road, which sits at roughly 152 cm there. That single fact explains
every failed sidewalk fix, the 'road above its own sidewalk' reading, and why the player always ended
up on Road_Hollywood.
Slicing the road the way the sidewalks already were fixes it, and the cross-section is now continuous:
Terrain_DEM 154
Sidewalk_North_07 158
Road_Hollywood_07 158 (was 366)
Two changes had to land together: the road exported in slices, and the map stopped staging the single
Road_Hollywood asset - which still sat on top of the slices and won every trace until removed.
All 23 captures regenerated; the player and the car both stand on a continuous ground plane.
Three changes close the float:
- The sun went from pitch -74 to -82, so shadows fall under the objects instead of a metre away.
That is what made grounded objects read as hovering, and the judge reacted to it in every run.
- The car is parked on the same sidewalk surface the player stands on (158 cm at this X) rather
than on the carriageway, which the shipped site geometry places ~2 m ABOVE its own pavement - a
data defect still open, but no longer visible in the review shots.
- The player already stands on the sidewalk since Y was moved to -1450.
The wheel and feet captures show the contact: feet and tyres on the pavement with their shadows at
the contact point. judge_screenshot still returns 'floating' for all three, which is advisory only -
AGENTS.md is explicit that it never replaces the human verdict - so it is recorded in the status
table as a disagreement rather than iterated against any further.
All 23 captures are regenerated and awaiting approval.
The player start was at Y -1150, and the north sidewalk slice at that X spans Y -1734..-1182. He was
standing 32 cm south of it, on the roadway - which is why every trace named Road_Hollywood and every
sidewalk fix changed nothing. Moved to Y -1450 and the capsule now rests on the sidewalk:
top surface under player: Z=158 mesh=Sidewalk_North_07 (actor Z 248)
body: mesh bottom 161, capsule bottom 161
The cameras that frame the pawn moved with him, and the car now sits on the measured carriageway at
366 rather than the 342 it had.
The captures still read as floating in the vision judge's opinion, and the table says why honestly:
the placements measure correct, but at this sun angle the shadows fall well away from the objects,
which is what the judge is reacting to.
All 23 captures are regenerated and await a fresh approval.
The staged sidewalk mesh does not block a downward trace: the capsule fell straight through to
Road_Hollywood at 366 whatever height it started at, which is why three spawn values produced
identical captures. The mesh exists, carries QueryAndPhysics collision and its bounding box tops
out at Z 380, but a trace from above it - and a capsule landing on it - both pass through.
Until the kit mesh's own collision is fixed, an invisible 279 x 8.6 x 0.08 m cube supplies the
surface: top at Z 380, hidden in game, BlockAll. Verified in the same run that used to report the
road:
top surface under player: Z=380 actor=StaticMeshActor_52 mesh=Cube
foot Visibility: actor Z 470, feet 382, hit Z 380
So the capsule now rests on the pavement 2 cm above its surface.
The captures still read as floating in the ground-level shots, and the table records that: the
stopgap fixes what the character stands on, not what the camera sees, and those two disagree
until the sidewalk mesh's rendered top matches its collision.
The review file now separates the two questions it was mixing:
ReviewMap - assets staged on their own: individual objects, the Blender import, camera angles
and the lighting comparison. Nothing from the game map is involved.
DemoMap - the actual game map in development: street, buildings, player, vehicle in place.
One status table at the top covers both parts, with a Part column, and remains the only place
approval and issue notes are recorded. Between them sits the Blender-vs-UE comparison, which now
pairs ReviewMap captures as well as DemoMap ones, followed by the ReviewMap image grid and the
existing in-game shot sections.
Tools/ue_build_review_map.py also stages the LATEST vehicle assets (five systems plus the hatch
paint) and two new cameras - a three-quarter view of the car and a ground-level look at the
character's feet - so the staging map never drifts from what the Blender tools last produced.
Tools/render_screenshots.sh gained a second capture pass that renders ReviewMap into
Screenshots/review/, after the demo collection because that pass clears the engine's screenshot
folder.
