The developers/aurelien sandbox scenes still reference legacy non-LOD
mesh paths (sm_book.mesh, sm_candlestick.mesh, ...) that don't exist
anymore — the production scenes were migrated to *_lod0/1/2.mesh.
Godot's full-project file scanner reads every .tscn at editor open
and emits 'Cannot open file' errors for each broken ext_resource,
even for scenes that the game never loads.
Mark developers/ as out-of-scope for Godot's filesystem walker with
a .gdignore at its root. The .import / .uid sidecars Godot had
generated for files inside (CheckLightmap.exr.import,
CheckLightmap.gd.uid) are auto-removed by the editor since they are
now orphaned metadata — only the source files (.tscn, .gd, .exr,
.lmbake) remain. Re-enabling the sandbox later just means deleting
the .gdignore; Godot will regenerate the sidecars.
The other diffs in this commit are Godot 4 canonicalising whatever
.tscn / .tres files were touched in the editor session that ran the
LightmapGI bake attempt: ext_resource uid= attributes added, format
bumped 2 -> 3, property order normalised. No behavioural change.

Discovered while playtesting the migrated build. Each fix has a
specific Godot-3-to-4 cause that the --convert-3to4 tool did not catch.
Fonts:
- Replace 4 .tres font wrappers (MKX_Base, kirsty_base/medium/title)
with FontVariation pointing at the .otf/.ttf source. Godot 3
DynamicFont with size= and font_data= is invalid in Godot 4 (those
properties don't exist on FontFile).
- Apply size 46 via theme_override_font_sizes/font_size on the 5
Labels that used kirsty_title.tres (LabelLoading + 4 in Summary).
- Drop the broken VisualShader text_outline.material from the 4
Labels in Summary — Index p_from_port errors in Godot 4 meant
COLOR was never written, so text rendered invisible.
- Migrate VisualShader nodes inside text_outline.material (compressed
asset; updated by the inspect/migrate scripts).
Translations:
- Move project.godot section from [locale] (Godot 3) to
[internationalization] with locale/translations=... (Godot 4). The
old section was silently ignored so tr() returned the raw msgid.
- Adjust Setting.translate_int_to_locale to return "en"/"fr" to
match what the .po files declare (was "en_GB"/"fr_FR", which Godot
3 fell back from automatically but Godot 4 does not).
Label alignment (Godot 3 names not auto-renamed):
- align -> horizontal_alignment, valign -> vertical_alignment across
9 .tscn files.
Background / Loading / ChooseScene layout:
- Rewrite Background.tscn from a VisualShader-textured Panel to a
plain TextureRect (the visual shader connection ports went out of
bounds in Godot 4, leaving the panel grey on scene reload).
- Set layout_mode=1 + anchors_preset=15 on BackgroundPicture
instances in Main.tscn and Loading.tscn — Godot 4 inheritance no
longer applies the .tscn-root's anchors to an instanced child
unless layout_mode is set to Anchors mode explicitly.
- Replace scroll_horizontal_enabled (Godot 3) with
horizontal_scroll_mode/vertical_scroll_mode (Godot 4) on
ChooseScene's ScrollContainer.
- Add theme_override_styles/panel = StyleBoxEmpty on the
ScrollContainer (Godot 4 ScrollContainer ships a default dark
panel style that Godot 3 did not).
- Hide BackgroundTile in Template.tscn — it points at
UI-level-btn-shadow.png (228x228, 83% opaque black) which used to
render at natural size in Godot 3 but is stretched to fill the
456px rect in Godot 4, leaving a big black square below each
thumbnail. The proper drop-shadow needs a shader or 9-patch.
- TextureRect.expand=true (Godot 3) -> expand_mode=1 (Godot 4) on
ThumbnailLevel and TopPart's content rects.
Lighting:
- background_mode 3 (which used to mean Sky in Godot 3) -> 2 (Sky in
Godot 4; 3 is now Canvas, producing a black background).
- background_sky -> sky, background_energy -> background_energy_multiplier,
fog_color -> fog_light_color, fog_height_min -> fog_height; drop
fog_height_enabled / fog_height_max / fog_height_curve /
dof_blur_far_distance (no longer exist).
- Add fog_mode = 1 so Godot 4 uses fog_depth_* instead of the new
default fog_density-based exponential fog (which rendered as a
thick white cloud).
- ambient_light_energy 1.55 -> 0.4 — the new pipeline interprets
the value much more strongly so 1.55 produced a saturated pink scene.
- Remove the light_data = ExtResource(41) reference to
WarCraft.lmbake — Godot 3 baked lightmap binary format is
incompatible with Godot 4. Re-bake in editor when ready.
