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.

"""Empty both Unreal maps before a build, and verify they really are empty.

|
<engine>/UnrealEditor-Cmd <uproject> -run=pythonscript \
|

-script=<repo>/Tools/unreal/ue_recreate_maps.py -nullrhi -unattended -nopause -stdout
|
|
|
|
Why this does not delete the `.umap` files: `LevelEditorSubsystem.new_level()` refuses a path whose
|
|
package is still in memory, and `EditorAssetLibrary.delete_asset()` leaves the file on disk with the package
|
|
still registered, so deleting and recreating in one session always returns False. Measured:
|
|
|
|
new_level fresh -> True
|
|
delete_asset -> True
|
|
disk file still present -> True
|
|
new_level again -> False
|
|
|
|
What does work, and is what the maps actually need, is clearing every actor and saving: the builders stage
|
|
everything they use, so a level with no actors is the blank slate. Anything an experiment left behind - an
|
|
actor from a probe, a duplicated vehicle, a stale shot camera - is gone, which is the failure this step
|
|
exists to prevent.
|
|
|
|
Both maps are emptied and saved, and the script reports the actor count it left behind.
