I have a set of armors that are made of separated pieces like belts. All the pieces are joined as one object, but topologically they are separated (because they were made in Zbrush with mask+extract technique). When i parent an armor to armature with automatic weights, here is what happens:

As you can see, belts are moving different and each part has different weighting which causes intersecting and other bad looking things. I've tried manually painting/fixing weights, but it is almost impossible to do it correctly on separate objects like these. How to handle this problem?
