DrapeFix: Cloth Drape for Fitted Outfits, Keeps Shape Keys and Weights
Yes. Fit the outfit first, in rest pose, then drape it. DrapeFix is the step after fitting.
Yes. Names, count and order stay, and every key moves with the cloth. Keys with a body key of the same name are checked against the body with that key on.
No. DrapeFix does not make clothes. It drapes the outfit you already have and keeps its keys, weights and UVs.
No. The settle runs in memory on a temporary copy. Only a hidden backup of the original stays in the file.
It works on a mesh garment on the same armature as the body. We tested it on the VRoid sample avatar, Seed-san and CC0 MakeHuman bodies. BOOTH outfits are not in our tests yet.
Yes. Restore Original gives back the original exactly, and one Ctrl+Z undoes a drape.
