goz problem on hidden part of mesh

I use goz between modo and zbrush while I find one problem:
If you hide some part of mesh in zbrush and goz it to modo, that hidden part will not go with the mesh. Then if you want to goz back to zbrush, zbrush will say the topology has been changed, you have to make a projection. But if you have some layers on original mesh, all of these will be lost when projection.

Is there any way to keep or restore those layers?

Is this only happening when you have hidden geometry when you goZ to modo?

yes, i think zbrush will only goz unhidden parts of mesh to 3rd app but it only recognizes that mesh which is gozed back as a total new mesh just because the geometry is different.

Why zbrush can not just recognizes this gozed back mesh as part of the original mesh? This is not logic.

it is probably changing the point order.
just don’t goZ with hidden geo.
