Cloth / Wind Sheet
Cloth motion remains readable while the pinned edge and sheet response stay coherent under wind.
What you are seeing
Scene
A pinned-edge cloth sheet with visible anchor points, wind direction cues, and readable collision space for a grounded soft-body proof scene.
Why it matters
Show pinned-edge cloth response, wind-driven motion, and soft-body stability in a visually legible scene.
Pass condition
The sheet should sway, settle, and remain coherent without explosive instability, while the pinned edge stays visually obvious in the reference setup.
Proof views
Use Public proof for the clean buyer-facing read, Event focus for adaptive slowdowns around the key moment, and Debug proof for contact cues, overlays, frame numbers, and proof-lane instrumentation.

Systems exercised
- PBD cloth
- soft-body constraints
- pinned vertices
- wind forcing
Known limitations
- This public scene is a proof pass, not a garment-authoring workflow.
- Large self-collision and production cloth authoring still depend on integration scope.
Recommended context
Useful when a buyer needs visible evidence that UPE reaches beyond rigid stacks and vehicles.
Determinism status
- same build: scene-capable in the reference lane
- cross-run: validate in deterministic config
- cross-platform: not broadly claimed
- snapshot / restore: supported by broader tooling
