The fascia anchors have said collateral:"gutter" since Sprint 6 and nobody
priced one — collateralFor('gutter') returns null, backyard_01's house is a
free failure. Proposal rides in the asset like the carport's did: 90, between
the gnome (25) and the carport (180), with the band reasoning next to the
constant. A rules the number.
house_yardside_wrecked_v1: same origin/footprint/facade (shared _house_facade
helper — intact house BIN chunk byte-identical to the committed GLB, only the
three new price extras differ), fascia torn through the anchored span, left
run hanging by its last bracket, right run kinked ON the grass, downpipe out
of plumb, offcuts flat on the lawn. No fascia_anchor_* empties survive — you
cannot re-tie to a ripped eave.
collateral_key is new and explicit: unlike the carport, the structure and the
thing you take have different names, so the key names which collateral string
the value prices.
All 33 GLBs byte-identical across two full factory runs; the house pair also
byte-identical between --only and full runs.

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
|
||
blender -b -P tools/blender/build_yard_assets.py -- --cards # re-render the end cards
|
||
|
||
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.

"""A kid's 16-inch bike, dropped against the fence (SPRINT11 §Lane E — the
|
||
per-client prop). The Hendersons have a kid; the kid has a bike; the bike is
|
||
against the fence because that is where bikes live. It exists to make the
|
||
job sheet's brief — "the seedlings have to be alive when we get back" — land
|
||
on a yard that visibly belongs to somebody.
|
||
|
||
LEAN IS BAKED IN, and that's deliberate. A bike does not stand up on its own,
|
||
so an upright GLB would be a prop that reads as a bug the moment it's placed.
|
||
The whole thing is built through `_tilt()`, a rotation about X applied to
|
||
every point at author time.
|
||
|
||
The origin is the ground line, and the tilt is about the X axis THROUGH that
|
||
origin — so the tyre contact points (z = 0) map to themselves and the bike
|
||
sits on the ground, not through it or above it. Drop it at ground level like
|
||
the gnome and rotate about the up axis to aim it.
|
||
|
||
** WHICH WAY IT LEANS — read this before you place it, Lane A. **
|
||
In THIS file the bike leans toward +Y, because Blender is Z-up. You do not
|
||
work in Blender. The exporter maps Blender (x, y, z) -> glTF (x, z, -y), so
|
||
in three.js the bike leans toward **-Z**, and -Z is the side the fence goes.
|
||
Put the fence on +Z and the bike will lean away from it into thin air, which
|
||
is a bug that looks exactly like a physics bug and isn't one.
|
||
|
||
I wrote "+Y is the fence side" here first and it would have been a lie by the
|
||
time it reached you — this is the axis trap the header of e.test.js exists to
|
||
catch, and it caught me writing the docstring, not the geometry. There's now
|
||
an assert in that file pinning the lean to -Z in browser coords, so if anyone
|
||
ever un-tilts this or flips the export, the suite says so instead of you
|
||
finding out by eye. Stand it ~0.10 m off the palings — the bars, not the
|
||
tyres, are what touch a fence.
|
||
|
||
Not breakable and not priced: it's juice, not a trap. See my THREADS note if
|
||
you want it to be collateral — that's your call and it has a number in it.
