Drops the parcel.png sprite (which baked the parachute and the box
into a single image) for a real 3D model: assets/parachute.glb is
the CC-BY 3.0 « Parachute » by Poly by Google, decompressed from
poly.pizza's static.poly.pizza CDN.
The parcel template now stacks four meshes inside one Group so they
move as a unit:
- the loaded parachute (centered + scaled to ~1.6 world units max)
- a 0.46×0.36×0.46 brown box with metal-low MeshStandardMaterial,
positioned at y = -0.96 — right below the parachute's harness
point — so the model's strings appear to terminate on it
- two thin black straps wrapping the box (0.04-thick boxes, one
horizontal one vertical) for visual reinforcement that the cargo
is tied down
spawnParcel clones the template (deep), per-instance clones every
material so opacity can be modulated independently per parcel, and
adds a slight pendulum sway + slow Y spin. Falling/scale-up/fade
logic adapted from the sprite version. Cleanup disposes the cloned
materials when a parcel exits.
HTML credit comment extended to attribute both the airplane and the
new parachute under CC-BY 3.0.
