Verifying the GLBs in three.js (not just Blender) showed four assets reporting inflated bounds: tramp_01 came back 3.29 x 1.27 m against a true 2.96 x 0.78. Box3.setFromObject expands each mesh's LOCAL box by the world matrix, so a node carrying a rotation over-reports — the same trap Blender's obj.bound_box sets, and what three uses for frustum culling. Joined nodes inherited parts[0]'s rotation, which for an arc is half a segment step off-axis. Applying rotation at join time makes every local box axis-aligned, so the default Box3 path is now correct for consumers and culling is tight. World geometry is unchanged; the exported dims are identical. Adds tools/assetcheck/, the three.js harness that caught this. It's the only check that can: a Blender round-trip exports Z-up->Y-up and imports Y-up->Z-up, so a broken export_yup flips back and passes green.

SHADES — yard asset factory (Lane E)
|
|
====================================
|
|
|
|
ONE deterministic script that regenerates every nature + hardware GLB the game
|
|
needs. Nothing here is hand-edited afterwards: change the script, re-run, commit
|
|
the new GLBs (PLAN3D §0, "asset copies rule").
|
|
|
|
Run:
|
|
blender -b -P tools/blender/build_yard_assets.py
|
|
blender -b -P tools/blender/build_yard_assets.py -- --only tree_gum_01
|
|
blender -b -P tools/blender/build_yard_assets.py -- --no-verify
|
|
blender -b -P tools/blender/build_yard_assets.py -- --no-debris
|
|
|
|
Outputs (resolved from this file, so no absolute home paths):
|
|
web/world/models/*.glb nature, hardware, ref_capsule
|
|
web/world/models/debris/*.glb copied verbatim from the 3D-STORE library
|
|
web/world/models/textures/grass_atlas.png
|
|
tools/blender/contact_sheet.png verification render vs the 1.7 m capsule
|
|
tools/blender/asset_report.json measured dims / tris / node names
|
|
|
|
Idiom follows ~/Documents/Destroyulater/3D-STORE/racks_to_glb.py:
|
|
reset_to_empty() per asset -> build under a root empty AT THE ORIGIN ->
|
|
join by group -> stamp custom props -> export_scene.gltf(export_yup=True,
|
|
export_extras=True, export_apply=True).
|
|
|
|
Gotchas this script respects (all learned the hard way elsewhere in the house):
|
|
- Blender's glTF importer leaves objects at rotation_mode='QUATERNION', and
|
|
assigning .rotation_euler is then SILENTLY IGNORED. That is the bug that hid
|
|
every fix across booth_room v3..v18. import_glb() forces 'XYZ' immediately.
|
|
- Material.blend_method is deprecated under EEVEE Next; prefer
|
|
surface_render_method when it exists.
|
|
- Blender is Z-up, glTF is Y-up. Build Z-up here; export_yup=True flips it.
|
|
A branch_anchor at Blender (0, 0, 3) arrives in three.js at (0, 3, 0).
|
|
- Root empties stay at the world origin so `obj.parent = root` needs no
|
|
parent-inverse juggling.
|
|
|
|
Contract notes for other lanes (see THREADS.md):
|
|
- Trees expose `trunk` + `canopy_01..03` as separate nodes so Lane A can sway
|
|
canopies without moving the trunk, plus `branch_anchor_*` empties for
|
|
world.anchors.
|
|
- house_yardside exposes `fascia_anchor_01..03` — the fascia is a lie
|
|
(DESIGN.md), and these are the anchors that are supposed to betray you.
|
|
- sail_post is exported VERTICAL with a `rake_pivot` empty at the footing and
|
|
a `top_anchor` at the head. Rake is a gameplay decision, so it is a runtime
|
|
rotation about rake_pivot, not baked into the mesh.
|
|
- shackle/carabiner/turnbuckle keep their failure-mode part as its own node
|
|
(`pin`, `gate`, `body`) so the break animation can move just that piece.
