- ue_import_site.py: switch walkable surfaces (terrain, road, sidewalks) from
CTF_USE_COMPLEX_AS_SIMPLE to CTF_USE_SIMPLE_AND_COMPLEX so the capsule
blocks against the auto-generated simple collision as well as triangles.
- Re-imported site meshes, rebuilt DemoMap with the PlayerStart cap at Z300.
Unresolved: packaged plain launch still falls through at spawn in the last
verified run (capsule Z-123 -> -1960, no ground trace hit). User confirms the
site geometry RENDERS (visible in the distance) but the player is not standing
on it. Needs an in-editor/in-window collision verification — headless traces
are unreliable. Continue on this branch; do not merge to main.
- ue_import_site.py: auto_generate_collision=True so FBX static meshes get
real collision geometry (they imported with none -> complex-as-simple had
nothing to use, player fell through).
- ue_build_demo_map.py: PlayerStart cap raised to Z300 so the capsule feet
start above the ~Z99-138 terrain surface there (an embedded spawn point is
rejected -> 'NO PLAYERSTART with positive rating' -> origin fallback).
- Re-imported site meshes + rebuilt DemoMap with the above.
KNOWN-UNRESOLVED: packaged plain launch still spawns the capsule around
Z-123 and falls; downward trace finds no geometry. Map assets are all present
in the pak and referenced; runtime collision behavior needs a visual/interactive
check (headless commandlet traces are unreliable). Investigate on this branch;
do not merge to main.
- street_mesh.py: continental zebra markings (0.5 m bars, 0.5 m gaps, 3 m
band) at all three signalised crossings, triangles not quads (FBX SDK
refuses to triangulate the crown-twisted quads), stripes +6 cm above the
DEM so they stay above the road surface; winding flipped so every street
surface faces up (road/sidewalks/markings were 100% down-facing and
invisible in engine once the terrain stopped covering them).
- terrain_from_dem.py: cut a 10.7 m corridor around the Hollywood Blvd
centreline so road, kerbs and sidewalks are not buried under the terrain;
sidewalks themselves cover the transition band, walk-check stays at 0 holes.
- Blender builders save with a writability guard + fatal failure: *.blend
is LFS-lockable and checks out read-only; a failed save previously left
downstream steps building from stale files.
- ue_import_site.py: Crossing_Markings imports with no collision (paint on
the road); ue_build_demo_map.py stages it and chmods the lockable .umap
before saving (save_map silently returned False on read-only maps).
- ue_build_review_map.py: demo-crossing camera moved to the real crossing
(s=130.1 m -> UE -24291,-1340) and fixed the ensure_writable path (was
missing the .umap suffix, so the chmod never fired).
Tools/ue_build_demo_map.py builds /Game/Hollywood/DemoMap: sun, sky, the hero
facade on the building line, six site meshes imported with collision, and a
player start on the north sidewalk. Tools/ue_import_site.py imports the site
FBXs; terrain, road and sidewalks use complex-as-simple so a simple hull cannot
ramp over the kerbs. Art/blender/site/export_site_fbx.py exports one FBX per
object so each can carry its own collision.
Reset (R) and pause (Escape) join the character and the input context: reset
restores the spawn transform and clears momentum, pause is a real game pause that
releases the cursor. DefaultInput.ini captures the mouse on launch.
Three placement defects found by measuring the imported actors rather than
trusting the plan: the spawn was on the wrong sidewalk because the FBX flip
inverts north, a mirror I added to the exporter double-corrected an already
correct sidewalk, and the street meshes only carry part of the north walk - the
rest is terrain.
