Fix Cloth Animation by converting it to Shape Keys and then sculpting.
How it Works:
The Addon converts your animation to shape keys. in other words, it converts Cloth, Softbody or MeshSequenceCache modifier to shape Keys.
So these 3 modifiers:
-MeshSequenceCache (When Importing Alembic)(Marvelous Designer)
it will DUPLICATE your object, (Hide/Remove the original mesh).
You can edit the shape keys in sculpt mode or edit mode.
Hotkeys: (You can change them)
Mouse Button4 -> previous shape key
Mouse Button5 -> next shape key
-Using the frame step of Frame Range inside the output property tab, you can skip frames (Stepping). (Don't Forget to change it back).
-You can apply the Subdivision Surface modifier to your converted mesh and keep shape keys with the animation. (Note: the more levels of subdivision and number of shape keys, the longer it takes to apply)(also blender might stop responding, SO WAIT).
