[1.1.0] - 2026-07-16

PMX.Submesh and Mesh.submeshes — per-material index ranges recovered from the PMX material section’s surfaceCount, so a single part (e.g. a carbody skin) can be isolated from a whole-model PMX. No text is decoded to build the table: every name/memo is stepped over with the existing skipString(). A per-triangle material id is threaded through both degenerate-drop passes (pre-weld index-duplicate, post-weld weld-collapse) so offsets stay correct even when a dropped face sits in the middle of a material’s range. Best-effort: a truncated/malformed material section yields submeshes: [] without affecting positions/indices. (#4)

Initial release: native-Swift PMX 2.0/2.1 geometry reader — vertex positions and the triangle index buffer, with left-handed → right-handed conversion, seam welding, degenerate-face culling, and uniform scale. Dependency-free (no ICU/Unicode needed, since text fields are never decoded).
