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_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.
