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.
Tooling tests
Standard-library unittest tests for the host-side tools in Tools/. They never start Blender, Unreal, or the game; anything that needs those processes is verified by the tool itself and recorded in Docs/release-checks.md instead.
Run from the repository root:
python3 -m pip install -r requirements-tools.txt
python3 -m unittest discover -s Tools/tests -t Tools -p 'test_*.py'
The -t Tools top-level directory is required: the tests import the tool modules by their plain names (import input_emulation), which is why Tools/tests/ carries an __init__.py.
Individual test:
python3 -m unittest Tools.tests.test_input_emulation -v
What belongs here
Test the pure parts — argument parsing, key/coordinate encoding, geometry maths, licence gating, report formatting, decision classification. Network, Blender and Unreal calls stay out: a test that needs a paid API, a display, or an engine process is a manual check, not a unit test.
When a tool's logic is buried in main(), extract it into a function so it can be tested directly. That is a tooling improvement, not test scaffolding.
Geo (Geo/tools/) and Blender (Art/blender/*/) builders are tested the same way once their pure parts are extracted; note the module path in the test.
