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 and staged by the demo builder.
Adding neighbours exposed a pre-existing placement bug that could not be seen
while the hero stood alone:
- UE south is +Y (south sidewalk Y +718..+1447), but the hero facade sat at
Y -1450 on the NORTH side and at X -12024..-9420, which is 26 m east of the
6840 footprint (the frontage gap 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; frontage and
north buildings export without 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 going to silhouette.
Screenshots re-rendered; the four demo views are marked needs-review because
the whole block changed.
- 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.
