Clothing

The execution model is in blender-core. The rig and weights are in blender-character-rigging, classic cloth settings in blender-simulation, and Roblox layered clothing cages in blender-export-pipelines (references/roblox.md).

How pros build game clothing

1. Shape: start from the body (extract + offset) for fitted clothes, or from flat patterns sewn by cloth sim (Marvelous Designer or Blender cloth with sewing springs) for loose ones. Simulate on the body in its rest pose (A/T).
2. Game mesh: retopo the high/sim result to clean, even quads with loops at the joints (elbows, knees, shoulders get 3 loops), then UV it. Bake folds into normal maps (blender-texture-baking) so the low mesh stays light.
3. Skin: copy weights from the body (same bones, same influences), clean them (limit 4, normalize, drop < 0.001), then blend toward smoother weights only on loose parts (skirts, coats) and add extra bones for those.
4. Hide what's covered: delete body faces under the garment (save tris, stop poke-through) or mask them per outfit. Keep one ring of skin under cuffs and collars.
5. Verify in motion: stress poses (blender-character-rigging stress_poses.py), then --check in each. Fix by easing (offset), smoothing the body there, weight tweaks, or hiding.
