Living roadmap for this project. This file is the single source of truth for current progress.

0.1.0 — Local setup and walkable Hollywood block (weeks 1–6)

Environment setup

Status detail in Docs/setup.md; workstation audit in Docs/environment.md; pins in Docs/toolchain.md.

• Update Bazzite using its supported mechanism; verify NVIDIA driver and Vulkan operation.
• Register an Epic account and accept the Unreal license; obtain a pinned Linux engine build or build from Epic's authorized source repository.
• Validate Unreal runs on Bazzite before asset production (not an officially supported distribution).
• [-] Install the engine-required compiler/SDK, Git, Git LFS, and an editor; use Distrobox for isolated CLI dependencies where useful.
• [-] Pin Blender, MPFB, Blosm, and QGIS versions; confirm add-on compatibility; record in docs/toolchain.md.
• Create repository structure (Game/, Art/, Geo/, Tools/, Docs/) with LFS tracking and ignore rules applied.
• Keep project and Derived Data Cache on SSD storage; reserve several hundred GB for engine, assets, caches, builds.

Project bootstrap

• Create a C++ Unreal project with Blueprint gameplay iteration and Enhanced Input.
• Package and launch a blank Linux build.
• Export one static mesh from Blender and import into Unreal; verify scale and materials.
• Export one MPFB character with baked materials and deform skeleton; verify import.
• Document initial setup in Docs/: engine install, project checkout, fresh-checkout build procedure.

Geographic data

• Save a versioned OSM extract; document date, bounds, and source in Geo/.
• Acquire separately licensed elevation data if needed. Needed and acquired: USGS 3DEP 1 m DEM in EPSG:26911, public domain, NAVD88, 984 KB committed (Geo/manifests/2026-11-06-3dep-dem.md); measured relief 3.94 m.
• Download the 3DEP 1 m DEM for the demo bounds, reproject it to EPSG:26911 with the recorded origin and vertical datum, and record the source, clip bounds, and checksum in Geo/.
• In QGIS, set a suitable local projected CRS (e.g. EPSG:26911) and record a local origin. EPSG:26911, origin and projected easting/northing are recorded in Geo/manifests/local-origin.md with PROJ 9.9.0 control points; QGIS 4.2.3 is installed for the DEM reprojection step.
• Verify the address, building footprints, and demo boundaries for 6840 Hollywood Blvd against source data.
• [-] Import OSM blockouts through Blosm; clean and detail them in Blender. Imported 2026-11-06 (Art/blender/blockout/blockout-2026-11-06.blend, 87 meshes, scale verified 1:1 against OSM); cleaning and detailing not started.
• Preserve geographic coordinates in metadata; define explicit meter→centimeter conversion to local Unreal coordinates.

Asset production

• Establish a consistent scale test, named export presets, and repeatable import settings.
• [-] Collect reference photography for manual façade work. Local only, never committed: Art/reference/ is gitignored, and what each set establishes is written up in Docs/reference-notes-hollywood.md. Still missing: the east retail neighbours 6806–6822, a night frame of the hero façade, and a sidewalk-level view of the hero entry.
• Download reference photography for the two north-side buildings inside the 50 m buffer — TCL Chinese Theatre (OSM way 424105908, 6925 Hollywood Blvd) and Madame Tussaud's (way 424105889, 6933 Hollywood Blvd). Done 2026-11-06 with Tools/commons_fetch.py against the Wikimedia Commons API: eleven frames in the local Art/reference/north-chinese/ and Art/reference/north-tussauds/, provenance in each sidecar.json, nothing committed.
• Model hero façade for the El Capitan Entertainment Centre site.
• Model surrounding block frontage.
• Model simplified background buildings directly across Hollywood Boulevard.
• Build sidewalks, roads, and collision meshes. Ground must follow the DEM: 3.94 m fall along the block, ~2 % crown between the gutters at ±10–11 m from the centreline, north sidewalk higher than south. Kerb height is an unresolved assumption — the DEM does not resolve it (Geo/verification/2026-11-06-cross-sections.md).
• Materials and look development for all exported assets.

Gameplay

• First-person movement, mouse look, and Enhanced Input bindings.
• Collision, reset, and pause functionality.
• Walkable sidewalks and a designated street crossing. Crossing chosen: mid-block signalised crossing, OSM way 385648319, at 130 m along the block (Geo/verification/2026-11-06-street-profile.md).
• Fixed daytime lighting and basic ambience.
• Geographic attribution display ("© OpenStreetMap contributors" + license link).

Release checks

• Player can traverse both sides of the demo without falling through geometry.
• Building placement, street scale, and site identity checked against references.
• No blocking collision or packaging defects.
• 60 FPS at 1440p on the dev workstation (Bazzite, Ryzen 7 7700X, 64 GB RAM, RTX 5070 Ti 16 GB) using a documented quality preset; record upscaling state; report performance without frame generation.
• Fresh project checkout builds with the documented external engine installation.
• Package Linux build with documented controls.
• Tag v0.1.0 and write CHANGELOG.md entry; then remove this section.
