Regarding animation custom armature mesh INFLUENCE

Hi,

is there any way to have a custom bone ? AND by that i DONT mean only the shape, i mean the INFLUENCE.

For example, i want that at the end of a bone, there is a cube (or any custom mesh), and that mesh is parented to the bone and its Volume (Vertexes?) shall influence the animation mesh.

Any idea ?

To parent a mesh to a specific bone in an armature, select the armature and go to pose mode.
Select the mesh, then the bone --> Ctrl P --> Set parent to bone.

If the mesh is supposed to influence another mesh geometry, one option would be adding a Cast modifier to that geometry.
Dynamic paint might also be suitable for that purposeā€¦
