The player never fell through - it stood on an invisible 8 m box. The imported Terrain_DEM carried only a bounding-box simple collision proxy, so every downward trace in the block hit Demo_Terrain_DEM at Z 819 (the mesh bbox max) and the road/sidewalk underneath were unreachable. The view from up there looked plausible, which is why it read as working. - add UGigLineAssetTools (C++): set complex-as-simple collision on a static mesh; UE 5.8 exposes ECollisionTraceFlag, not bUseComplexAsSimpleCollision, and Python cannot set it at all. - builder forces + saves the terrain asset as complex-as-simple (the flag lives on the asset, so saving only the .umap loses it). - spawn (-13336, -1150, 600): inside the carved corridor; lands on the road at Z 456 (feet 368 on road top 366). - HighResShot 1280x720, not "1280 720" (that is multiplier 1280). - keep SIM + single ground-probe diagnostics (TEMP QA).
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.
