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.
