UE export hygiene (unreal-export skill checklist) plus a gameplay defect the new probe caught: - FBX export now uses mesh_smooth_type="FACE" (was OFF, which is why every import logged "No smoothing group information was found"), and the round parts are shaded with shade_smooth_by_angle(35 deg) before export, so columns and medallions read round instead of faceted. - SM_HeroFacade had complex-only collision, so capsule sweeps and line traces passed through the wall: the player could walk through the hero facade. auto_generate_collision was tried and rejected (coarse hulls bulged into the street; the QA wall probe went 0/35 -> 2/35). It now uses UseComplexAsSimple, saved on the asset, like the terrain. - New -qaselftest facade occlusion probe: 40 m traces sideways from the road centre at walking height, required only where a building is staged (explicit X spans mirroring ue_build_demo_map). Result 0/9 -> PASS, alongside transect 0 holes and wall probe 0/35. Docs: release-checks records the probe and both collision attempts; Tools/README lists the new phase; MEMORY records the smoothing/collision lessons.
Gig Line
A Linux-first Unreal Engine game about walking and driving through a real city. The first release, 0.1.0, is a walkable exterior demo around 6840 Hollywood Blvd / El Capitan Entertainment Centre, covering the south-side frontage between Highland Avenue and Orange Drive plus the north-side frontage within 50 m of the boulevard.
Status
0.1.0 is in progress. The workstation, engine, geo pipeline and project bootstrap are done and verified; a walkable DemoMap exists with terrain, street, sidewalks, kerbs and the hero façade placed from measured coordinates. Façades are still blockouts, and materials are flat colours — both are planned patches.
Current tasks are in TODO.md and the development plan is in ROADMAP.md; what was learned the hard way is in MEMORY.md.

Getting started
git lfs install # required: content, images, audio, and geo files are LFS-tracked
git lfs pull
Tools/check-lfs.sh # verifies the lfs filter is active and files are stored as pointers
The engine is installed outside the repository and pinned in Docs/toolchain.md. Setup is in Docs/setup.md; building and the content pipeline are in Docs/build.md.
