Marvelous Designer hands cloth on as per-vertex motion: Alembic (HDF5 or Ogawa) or garment-only caches (Maya .mc/.mcx, Point Cache 2, MDD in two variants). Export options cover weld vs unweld seams (which changes vertex counts and object splitting), thickness, merged vertices, unified 0-1 UVs, optional avatar shape, scale, axis conversion and frame range; strain or stress as vertex colour is documented only for Alembic. Pattern, physical-property and sewing data travel only as an optional XML with the cache export. The pages do not say how fabric materials or simulation settings reach a renderer.

Curator qualifications: Paper and help pages read 2026-10-22; no network trained, no cloth exported. Help pages are dated snapshots (2025-10); the live pages were not compared.

Limitations: Paper and help pages read 2026-10-22; no network trained, no cloth exported.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
