The bpy.ops.export_scene.fbx argument block was duplicated in six scripts (hero, block frontage, north buildings, site, scale test, MPFB character) and all six carried mesh_smooth_type="OFF", which drops smoothing groups and made every Unreal import warn and every round part faceted. Tools/fbx_export_preset.py now owns the presets: - preset_kwargs(preset, selection, **overrides) is bpy-free and unit-tested; - export_static()/export_character() are thin wrappers that import bpy lazily; - ue_metric_v1 and ue_character_v1 keep the recorded scale contract (FBX_SCALE_NONE, apply_unit_scale, -Y forward / Z up) and use FACE smoothing. Callers switched: hero_facade_build, export_block_frontage, export_north_buildings, scale_test_export, mpfb_character_export, Art/blender/site/export_site_fbx. Verified by re-exporting every asset through the preset and re-importing all of them: 0 smoothing warnings on site, frontage and north buildings; packaging and -qaselftest all PASS (walk, transect 0 holes, wall probe 0/35, facade probe 0/9). 49 tool tests pass (9 new for the preset contract).

"""Tests for Tools/fbx_export_preset.py.

|
|
|
The preset module keeps its argument set in plain dicts and builds it in
|
|
`preset_kwargs()`, so the export contract can be checked without starting
|
|
Blender. Only `export_static`/`export_character` import `bpy`.
