The axis_forward:X / Blender-Z axle fix changed the reference pose but not the drive
(-2737 cm/s), and axis_forward:X also alters the shared character preset. Revert it.
The Chaos solver drives the wheel about the vehicle's Y (not the bone), and the
drive force is positive yet the car moves backward - the inversion is in the engine
torque / drive-force sign. Next: GetEngineTorque() sign or a SetupVehicle override.
Wheel axles were vertical in Unreal (the FBX armature conversion rolled them 90 deg
about X). Fix: axis_forward:X in the character preset and a Blender-Z wheel tail so the
axle lands on Unreal Y. This is correct (reference pose FL roll 180 / FR roll 0) but
does not fix the reverse: -drivetest still -2737 cm/s, and FinalRatio sign is a no-op.
The remaining cause is the Chaos wheel spin-axis convention or engine torque sign.
The motto band and moulded surround had the same burial as the medallions: offset
0.06 left their front face at Y -0.44, inside the 1.2 m-deep parapet, so the
'inset panel with a moulded surround' never rendered. Only the inscription (moved
to 0.40 in the previous commit) read.
- Band recessed at offset 0.34 (Y -0.16), surround proud at 0.43 (Y -0.07),
inscription stays 0.40 (Y -0.10).
- Band is now light stone (was stone_dark): a dark band at the parapet face would
have sat directly behind the dark inscription marks and swallowed them. The
reference is dark incised lettering on a pale band.
- Removed the dead duplicate 'Hero_MottoBand 0.40' entry - the earlier 0.06 match
won, so the 0.40 was silently ignored.
Rendered and judged; the advisory judge no longer flags the band.
The medallions were not just flat - they were buried. seat_on_front put
Hero_Medallion at offset 0.08 (front Y -0.42) while the 1.2 m-deep parapet stands
at Y -0.15, so both discs sat inside the parapet and never rendered. The motto
band and surround have the same burial (offset 0.06) and are a separate follow-up.
- Three stepped layers per medallion with per-layer prefixes so seat_on_front gives
each its own stand-off: Rim (0.55 m, dark, offset 0.36 -> Y -0.14), Field
(0.38 m, light, offset 0.43 -> Y -0.07), Boss (0.15 m, dark, offset 0.50 -> Y 0.00).
A single Hero_Medallion prefix would both flatten the relief and (via startswith)
swallow the specific prefixes, so it is removed.
- Moved from +/-6.2 (inside the inscription text, which spans +/-6.87) to +/-9.8.
- Fixed Tools/review/hero_iterate.sh, which still had the pre-tools-move
'cd dirname/..' and landed in Tools/ instead of the repo root.
Rendered and judged; the advisory two-model judge (no, 0.93) no longer flags the
medallions. Owner review pending.
The reference's most distinctive architectural feature is three lines of incised capitals across the attic.
inscription() lays 112 letter marks in three lines, in the shadow stone so they read as dark incisions at 45 m
rather than disappearing into a same-colour relief - which is exactly what the first attempt did.
Positioning was the lesson: the parapet is 1.2 m deep and stands in FRONT of the wall plane, so marks seated on
FRONT_Y were hidden behind it and rendered invisible. They are now seated on the parapet face (FRONT_Y + 0.40),
which is where the reference puts the lettering too.
Still open in the architectural pass, recorded in TODO.md: medallion relief (the discs are flush and empty),
banner lettering (needs a texture, not geometry), and depth on the capitals and window grilles.
Rows 4-6 re-rendered and pending.
The e2e asset check now completes: PASS on all six steps - empty maps 9 s, demo build 10 s, review build 9 s,
captures 80 s, judge 388 s, review file. Four breakages from the folder move had to be fixed first:
- ue_placement and ue_common are siblings of the scripts that import them, but the rewrite put only the tools
root on sys.path, so every Unreal commandlet died with ModuleNotFoundError. Both paths are inserted now.
- render_screenshots.sh resolved the repository root one level up, so commandlet paths became Tools/Tools/...
and the capture step failed in 0 s.
- the driver treated a result file left by an earlier run as success, which is how a ten-second 'demo build'
passed without building. Result files are unlinked before each step and child output streams to a per-step
log file rather than a pipe.
- two editors on one project hang instead of failing, so the driver refuses to start while one is running.
Also corrects ue_recreate_maps.py: LevelEditorSubsystem.new_level() refuses a path whose package is still in
memory and delete_asset() leaves the file on disk, measured create->delete->create returning False. The step
now loads each map, destroys every actor, saves, and reports the count it left (0), which is the property the
builders actually need.
Open question recorded in TODO.md: the rebuilt map holds 409 actors and 613 KB against 600 and 886 KB before,
and the ~190 missing ones look like the facade-kit and theatre-trim placements that run as separate steps.
One directory with sixty scripts stopped being navigable, and the grouping is also the sandbox boundary:
Tools/unreal/ commandlets and the two map builders, with ue_common.py and ue_placement.py as the
shared imports (they need the engine)
Tools/blender/ builders, exporters, the FBX preset, the MPFB character pipeline, blender_screenshots
(they need the Blender Flatpak)
Tools/review/ the visual loop: render_screenshots.sh, judge_screenshot.py, hero_compare.py,
build_comparison_md.py, e2e_asset_check.py, hero_iterate.sh, visual_loop.py,
visual_targets.json
Tools/gen/ image and texture generation: the ComfyUI driver, deterministic texture writers,
reference fetching
Tools/input/ OS-level input injection
root _common.py, check-lfs.sh, addon_compat_probe.py, sibling_asset_audit.py, tests/
Every moved script now resolves the repository root as ../.. and puts the tools root plus its siblings on
sys.path, so 'import ue_common' still works from unreal/. The test suite bootstrap does the same for the five
folders. render_screenshots.sh takes the folder as a third argument to run_cmdlet, and the e2e driver,
hero_iterate.sh and the comparison generator were repointed.
51 README rows now link to their new location, the README gains a Layout section naming each folder's
sandbox, and the architecture notes and Blender README follow the moves.
Verified: 108 tests pass, prettier is clean, judge_screenshot.py and hero_compare.py run from their new
homes, and the e2e run was aborted mid-way (it had been rebuilding an empty DemoMap for 15 minutes) and is
being rerun against the new layout.
