Fixed daytime lighting and basic ambience for the DemoMap: - Sun pitch -50 / yaw 120 (intensity 4, warm), sky light 2.6 with real-time capture, sky atmosphere, height fog, and an unbound post-process volume with fixed exposure (min = max brightness) so no shot washes out or crushes to black depending on how much sky it frames. - Root cause of the washed-out look was NOT the sun: Blender's flat diffuse colours do not survive the FBX->Unreal import. Every site material arrived white and the terrain arrived with WorldGridMaterial. The demo builder now creates and assigns M_Asphalt / M_Concrete / M_Ground / M_RoadPaint. - Crossing fix: each zebra band was its own object, so Blender renamed the duplicates .001/.002 and site assembly (exact-name append) kept only one. All bands are now a single Crossing_Markings mesh (36 verts, 3 bands). - Terrain gets a Ground_Earth material in the builder so it stops importing as a white grid. - Demo cameras: street-level no longer sits inside the facade body (was rendering its back face), and the crossing camera aims at the designated s=130.1 crossing (UE X -14956) looking along the crosswalk. Screenshots re-rendered; the four demo views are marked needs-review for the owner's approval. MEMORY.md records the material-import, exposure, light_color, band-naming and camera-bounds traps.

# Screenshots — visual review
|
|
|
|
Rendered in-game captures of the current project content, generated by
|
|
[`Tools/render_screenshots.sh`](../Tools/render_screenshots.sh). The PNGs are
|
|
committed alongside this README so a reviewer sees exactly what the build
|
|
rendered.
|
|
|
|
## How to regenerate
|
|
|
|
```bash
|
|
Tools/render_screenshots.sh
|
|
```
|
|
|
|
Rebuilds `Game/GigLine/Content/Test/ReviewMap.umap` from current content, runs
|
|
the game on it (and on the DemoMap for the walkable views), walks the fixed
|
|
camera list via `AGigLineShotActor`, captures each shot, copies the PNGs here
|
|
and exits — about a minute. The camera list lives in
|
|
`Tools/ue_build_review_map.py`; add new shots there, remove retired ones here.
|
|
|
|
## Scene conventions
|
|
|
|
- **Floor**: 160 m square, top face at Z 0. The character measures Z 0..83 cm.
|
|
- **Cubes**: `Cube_ScaleTest_A` rests on the floor, `Cube_ScaleTest_B` floats at
|
|
Z 2 m; both are exactly 1 m — the scale reference.
|
|
- **Lighting (review map)**: one warm key light plus sky fill, neutral exposure.
|
|
- **Lighting (demo map)**: fixed daytime — sun at pitch -50 / yaw 120 (intensity
|
|
4, warm), sky light 2.6, sky atmosphere, height fog, and a manual-exposure
|
|
post-process volume (min = max brightness 1.0) so a shot cannot wash out or
|
|
crush to black depending on how much sky it frames. Surface colours are
|
|
assigned explicitly in `Tools/ue_build_demo_map.py` (`M_Asphalt`, `M_Concrete`,
|
|
`M_Ground`, `M_RoadPaint`) because Blender's flat diffuse colours do not
|
|
survive the FBX → Unreal import.
|
|
|
|
## Review-map shots
|
|
|
|
All ☑ approved 2026-11-07 (re-rendered with the character and cubes restored;
|
|
user visual check passed).
|
|
|
|
> Naming: shots use their stable `Tools/ue_build_review_map.py` camera name (no
|
|
> index prefix), so adding or reordering cameras never renumbers files or
|
|
> orphans the old ones. Click an image for the full-size PNG.

## What to look for
|
|
|
|
- **Ground contact**: feet meet the plane with no gap and no shadow seam.
|
|
- **Scale**: everything checks against the 1 m cubes.
|
|
- **Façade rhythm**: six columns at 4.96 m across 25.75 m should read as the
|
|
photographs in silhouette.
|
|
|
|
## Known cosmetic issues
|
|
|
|
- Floor speckle from the `Constant3Vector` wiring in `Tools/ue_build_review_map.py`.
|
|
- Hero façade renders pale — Blender flat colours with no normal/roughness, so
|
|
it reads as untextured stone (the `0.1.4` façade patch, not a lighting bug).
|
|
- Banners and window panels float detached from the colonnade wall (next
|
|
modelling pass).
|
|
- Between kerb and building line, the walkable surface is the terrain mesh, not
|
|
a modelled pavement. |
