site-2026-11-06.blend gathers terrain, street and blockout into categorised collections: 281 objects, ~58k triangles. A downward raycast on a 1 m grid along both sidewalks and the designated crossing finds no holes, so nothing drops the player on either side. Two steps are flagged: 15.8 cm at the sidewalk's outer terrain seam and 10-13 cm ramps at the crossing flush transitions, steeper than a real 8% ramp. Sampling is projected through PROJ: placing points with the OSM spherical approximation put them metres off the UTM meshes and reported 91 phantom holes.
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
Pre-production. Workstation setup and repository scaffolding are in progress; no engine, content, or geographic data is committed yet. Current state is tracked in ROADMAP.md, and the per-task setup state in Docs/setup.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. The full procedure is in Docs/setup.md.
