Rigging High Resolution Swimming Suit vs Rigging Low Resolution Swimming Suit

But why can’t we rig a high resolution mesh directly? and what’s the difference between

rigging a high resolution mesh and low resolution mesh?

Take for example this Julie Model with a high resolution swimming suit mesh.

The number of points are so high that when I rig the model with a basic skeletal layout,

The low number of ZSpheres are unable to hold the dense swimming suit mesh.

So more ZSpheres would be required to hold the swiming suit mesh in place.

While this low subdivision mesh with only about 1K active points,

rigged with the same number of ZSpheres and layout,

can hold and move the mesh without affecting the swimming suit.

There are no unwanted artefacts pulled off by the arm ZSpheres at the waist or armpit.

For the dense swimming suit mesh, I had to add 2 sets of ZSpheres.

1 at the waist and 1 at the armpit.

just to hold the swimming suit and straps in place.
