- street_mesh.py: continental zebra markings (0.5 m bars, 0.5 m gaps, 3 m band) at all three signalised crossings, triangles not quads (FBX SDK refuses to triangulate the crown-twisted quads), stripes +6 cm above the DEM so they stay above the road surface; winding flipped so every street surface faces up (road/sidewalks/markings were 100% down-facing and invisible in engine once the terrain stopped covering them). - terrain_from_dem.py: cut a 10.7 m corridor around the Hollywood Blvd centreline so road, kerbs and sidewalks are not buried under the terrain; sidewalks themselves cover the transition band, walk-check stays at 0 holes. - Blender builders save with a writability guard + fatal failure: *.blend is LFS-lockable and checks out read-only; a failed save previously left downstream steps building from stale files. - ue_import_site.py: Crossing_Markings imports with no collision (paint on the road); ue_build_demo_map.py stages it and chmods the lockable .umap before saving (save_map silently returned False on read-only maps). - ue_build_review_map.py: demo-crossing camera moved to the real crossing (s=130.1 m -> UE -24291,-1340) and fixed the ensure_writable path (was missing the .umap suffix, so the chmod never fired).

Binaries/, Intermediate/, Saved/, DerivedDataCache/ — all generated. .gitignore covers them; do not add exceptions.
Engine
Installed outside the repository. Its path and exact version are recorded in ../Docs/toolchain.md. Nothing in this directory may assume a machine-specific engine path; the documented build procedure is ../Docs/build.md.
