OverMorpher Mesh Space is the release of what I showed a few years ago: https://hocuspocus-studio.fr/tools/overmorpher/

That’s a new 3dsmax plugin which works like a morpher, but on top of an animated mesh.

It can be placed over a skin modifier, or anything like a point cache or an alembic…etc

Each morph target follows the deformation of a reference vertex, so whatever the animation does before the modifier, the morph will always follow properly.

That’s really handy to add and animate deformations that your rig can’t do, or add different morphologies to copies of the same animated mesh.
