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.
