Built the map-content bisect the task asked for: Tools/ue_vehicle_probe_map.py duplicates ReviewMap, optionally adds one demo mesh and the pawn, and saves it as VehicleProbe. control (no extra mesh) Z 300 -> 297 rests on the review floor + Terrain_DEM Z 300 -> 498 thrown upward So Terrain_DEM alone reproduces the fault in a map that works. Two fixes were tried: - Tools/ue_clear_simple_collision.py cleared the auto-generated convex hulls from all 76 site/street meshes - the terrain had ONE convex element over 279 m - and set them to complex-as-simple. Still rises. - The terrain component set to QueryOnly, so traces hit it and physics ignores it. Still rises. Neither changed the behaviour, so the ejection is neither the convex hull nor the collision channel. The next probe is the complex triangles themselves: give Terrain_DEM no collision at all in the probe map and see whether the pawn falls. If it falls, the triangle winding is pushing bodies out of the ground mesh - the same inverted-winding family that made the sidewalk unstandable earlier. Both tools have README rows; the pawn is parked again.
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.
