The 0.1.2 blockout regeneration ran without --origin, so Blosm centred on the
extract instead of fitting the project frame. The frontage shifted ~119 m in X and
~2.4 m in Y and the hero fell outside the 6902/6838 gap - the verified placement
was silently undone, while every render still looked like a plausible block.
- Blockout regenerated with --origin 34.101545,-118.338718 (affine residual 0.0 cm);
frontage and north buildings re-exported and re-imported.
- Verified spans restored: 6922 -24276..-17700, 6902 -17749..-14591, hero
-14644..-12028 between them, theatre -12082..-8210, TCL -22889..-18442,
Tussaud's -27071..-22799.
- ue_apply_facade_kit now uses get_actor_bounds() (world space). It had used the
static mesh bounding box, which is building-line-local, so every kit piece was
placed ~12 km east of its building in empty ground.
- ue_import_north_buildings.py was missing 'import sys' (NameError, exit 255,
import silently skipped) - the same trap as the hero importer.
- Kit re-applied: 625 pieces across eight buildings; packaged QA still PASS
(walk, transect 0 holes, wall probe 0/35, facade probe 0/9).
New Tools/generate_facade_textures.py: deterministic, stdlib-only PNG generator for
four facade surface sets (ashlar stone, stucco, asphalt, concrete), each as base
colour (_BC) plus roughness (_R). Pure zlib encoder and hash-based value noise, so
re-running produces byte-identical files (verified by md5sum); ~14 s for eight 512²
maps.
ue_build_demo_map.py imports them into /Game/Hollywood/Textures and samples them
world-aligned: WorldPosition (cm) * 1/tile_cm -> ComponentMask(R,G) -> TextureSample
UVs, with per-material tile sizes (stone 440, stucco 260, asphalt 900, concrete
250 cm). A textured material skips the graph coursing deliberately - overlaying both
would double the course pattern.
Textures imported 8/8, hero 4/4 slots assigned, map saved; screenshots re-rendered.
0.1.4 materials pass plus the camera fix levelling exposed.
Materials (Tools/ue_build_demo_map.py):
- ensure_material() gains optional masonry coursing (world-space course height,
joint band, joint tint) and roughness variation, so facades read as coursed
stone/stucco instead of one flat specular plane.
- WorldPosition is in centimetres: course heights in metres are scaled by 100
(the first attempt divided by 0.55 and the coursing was invisible).
- connect_material_expressions returns False rather than raising, so every link
now goes through a link() helper that logs failures; UE has no
MaterialExpressionLess, so the joint mask is Frac -> Divide -> OneMinus -> Clamp.
- New materials: M_FacadeStoneShadow, M_FacadeGlass (specular 0.62 ~ IOR 1.5),
M_FacadeBanner.
- Material assignment is now per SLOT keyed on the imported slot material name.
It was slot-0 only, which on the hero is the banner, so stone, shadow stone and
glazing still wore flat Blender materials. Hero now 4/4 slots.
Cameras (GigLineShotActor + ue_build_review_map):
- Optional per-shot ShotFieldOfView; the shot tuples take a 4th element.
- Elevations use a 42-55 deg lens from across the street: with the cameras
levelled (0.1.2 follow-up) the building was small in frame, and tilting to fill
it is what breaks the verticals. hero-facade-front sky 39% -> 20%,
demo-spawn-view 23% -> 16%.
Screenshots re-rendered for the whole set.
