Fallen Bird Feather

Fallen bird feather, 9m long: a contour feather with a stiff hollow quill, a gently curved shaft and two vanes split by a few soft gaps, fluffy down at the base; a bird knob (pigeon grey with a dark bar / blackbird black / jay blue barred in black and white).

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
