Operator: base flora too dense + "the waving/shader doesn't look great".
Diagnosis: EVERY Synty flora prop (both biomes) uses the Synty/Foliage
VERTEX-wind shader — the transform root-tilt sway has been double-animating
all flora since 1.5, and ground-flush carpet props (Flowers_Flat,
Grass_*_Plane) visibly lift their edges when tilted.
- AmbientMotionConfig.SwayEnabled -> false (code default + the serialized
scene value): idle motion = the authored per-vertex shader wind (tips bend,
bases planted). Knob kept for A/B; walk-through RUSTLE stays as the
reactive layer the shader can't provide.
- AmbientMotionSystem: flat carpet props excluded from the flora cache
entirely — no tilt even from rustle.
- Flower density thinned deterministically: Flowers_Flat keep 40%,
Wildflowers/Sunflowers keep 50%, center (r<13) thinned harder (x0.6) —
17/38 drifts off; play/build area reads clear, flowers become ring accents.
Console clean; sway/rustle knobs remain live-tunable in the scene.
