 - **Modifiers on `EnhancedActionKeyMapping` do not survive saving.** Assigning `InputModifierNegate` to the mapping's `modifiers` reads back correctly in memory, even after a `gc.collect()`, but the saved asset reads `mods=[NoneType]`. Keep-alive references, explicit flag setting, and in-place saves all failed to change it. Workaround: bind one action per direction (W and S as separate actions) so no modifier is needed.
 - **A read-only packed `.umap` silently blocks `save_map`.** `EditorLoadingAndSavingUtils.save_map` returned `False` with no error until the file's mode was fixed (`chmod u+w`). Symptom: a rebuilt review map keeps three cameras after a fourth is added.
 - `-run=pythonscript` still swallows `print()`, so write results to a file; `/tmp` is visible to the commandlets even though it is not shared between agent tool calls.

+## 2026-11-07 — Hero facade build and review cameras
+
+- **The review floor is the only ground in the scene, and it is small.** Cameras 25 m from the building line look past its edge and see the black horizon band under the facade. Place facade cameras so both the facade and enough floor are in frame, or extend the floor.
+- **The facade's frontage faces Unreal -Y.** The FBX preset maps Blender +Y (north) to Unreal -Y, so the elevation looks at negative Y and a straight-on camera must stand at **Y < -1450 cm**. A camera at positive Y looks at the back wall; cameras inside Y -1443..+250 are inside the building and render flat blue.
+- **The imported mesh is centre-origin in X but not in Y or Z.** Bounds are `x -1302..1302, y -7..1250, z 0..1450` cm, so to put the front plane on the building line the actor goes at `Y = line + 7 cm`, and `X = east edge + half width`.
+- **`save_map` returns False, without an error, when the packed `.umap` is read-only.** The review map silently keeps its old camera list. `chmod u+w` the file before rebuilding; a `umap` that keeps rendering four shots after a sixth was added is this, not a caching problem.
+- **`StaticMaterial` is a struct**: `material.get_editor_property("material_interface")`, no `get_name()` on the wrapper.
+- **Screenshot PNGs must stay out of git.** They were committed once despite the AGENTS rule; `.gitignore` now carries `/Screenshots/` with a `!/Screenshots/README.md` exception.

 - [-] Import OSM blockouts through Blosm; clean and detail them in Blender. Imported 2026-11-06 (`Art/blender/blockout/blockout-2026-11-06.blend`, 86 meshes, scale 1:1 against OSM, re-framed into EPSG:26911 with a 0.0 cm affine residual); cleaning and detailing not started.
 - [-] Preserve geographic coordinates in metadata; define explicit meter→centimeter conversion to local Unreal coordinates. The frame is defined (`Geo/manifests/local-origin.md`: EPSG:26911, origin Hollywood × Highland, X east / Y north / Z up) and the ×100 conversion is now **verified** by the 2026-11-07 scale test, with the axis mapping recorded (north realizes as UE −Y). Left: build the production export preset for the actual site meshes using these settings.

 - [x] Establish a consistent scale test, named export presets, and repeatable import settings. Scale test = the three-cube calibration scene (`Art/blender/scaletest/`, regenerable via `Tools/scale_test_export.py`); named export preset `ue_metric_v1` (FBX settings in that script); named import preset `ue_metric_v1` (`FbxImportUI` settings in `Tools/ue_scale_test_import.py`). Both scripts are the templates for production asset export/import.
 - [-] Collect reference photography for manual façade work. Local only, never committed: `Art/reference/` is gitignored. **72 images in eleven folders**: hero façades to 4k, the El Capitan Theatre exterior series, premiere-night staging, Ovation Hollywood, the north side, and the Lee Drug neighbour. Gaps largely closed by the Flickr/web-search pass: the hero entrance is now documented (three portals with individual short flights — the inherited "eight steps, 12 m wide" is overturned), and the 6806–6822 retail run appears in an oblique 2013 frame. Still missing: a clean isolated frame of the door recess and a night frame of 6840 itself.
