In LW, you could use various tools to link simple geometry, usually 2pt polychains, to more complex geometry, animate/simulate the simple geometry and get equivalent motion out of the more complex meshes.
IIRC, “Hard-Link”, “Meta-Link”, and “Sock Puppet” were examples of this, there may be a couple more.
In Blender, what are the equivalent tools, workflows, and/or processes?
“Hard-Link” is interesting in that it sorta …::searching for words::… does a deformation by “Connection” – all Connected Verts are displaced equally, but the next set in the same Object is not. Good for rigid yet jointed objects.
