SwayMend - One-Click Physics for Hair, Tails & Capes
Does it work on models from Meshy, Tripo or Hunyuan3D?
Yes. Those come as glTF/GLB with vertices split at UV seams; SwayMend reads through the seams. If the hair is a separate shell, it builds the strand on that shell.
Do I need a rig?
No. On a bare mesh SwayMend makes a one-bone rig. If the model is already rigged, the strand attaches to the bone it grows from and follows your animation.
Will it change my existing weights?
Only on the strand's own vertices. Everything else is untouched, and Clear All restores the original weights exactly.
Does the motion export to Unity, Unreal or Godot?
Yes. It's baked to bone keyframes, which FBX and glTF export carry.
What's the difference between Lite and Pro?
Lite costs $1: 1 strand per model, Hair and Tail presets, up to 120 baked frames. Pro adds unlimited strands, all five presets, body collision, wind and unlimited bake length.
Will it clash with my other rigging add-ons?
SwayMend only adds its own bones (named SM_…), vertex groups and keys, and touches nothing else. If you hit a clash, message me.
